Motor Grease is a resin-forward hybrid from Myers Creek Cannabis Seeds that marries old-school gas with modern dessert nuance. Classified simply as indica/sativa heritage, it expresses a balanced profile that can lean sedating or uplifted depending on phenotype and harvest timing. Growers and consumers gravitate to Motor Grease for its dense, gluey trichomes, mechanical-shop aromatics, and unmistakably “greasy” mouthfeel that lingers on the palate.
In modern markets where tested flower averages roughly 19–21% THC across many legal states, Motor Grease commonly competes above that mean. Reports from growers and lab menus suggest batches frequently land in the low-to-mid 20s for THC by dry weight, with some high-performance grows pushing higher under optimized conditions. While CBD is typically trace (<1%), minor cannabinoids like CBG and CBC can appear in measurable but modest amounts.
Beyond potency, the strain’s appeal lies in consistency of bag appeal and its forgiving cultivation arc for an advanced beginner or intermediate grower. Dense, lime-to-olive flowers often show deep forest accents and streaks of purple when temperatures are steered late in bloom. Whether rolled into joints or pressed for solventless hash, Motor Grease has earned a reputation as both a connoisseur smoke and an extractor’s friend.
Breeding History and Origin
Myers Creek Cannabis Seeds bred Motor Grease to meet the contemporary demand for heavy resin, loud gas, and robust structure. The name evokes two titans of the modern gene pool—“Motor” as in Motorbreath and “Grease” as in Grease Monkey—though Myers Creek has not publicly released a definitive parental pairing. This approach mirrors a growing industry trend toward protecting intellectual property and guarding unique line-building, much like the “unknown strain lineage” entries cataloged by community resources such as SeedFinder.
Contextually, the strain fits a breeding moment defined by high-output resin hybrids that still retain nuanced flavor. Seed banks and marketplaces continually spotlight “new arrivals” and “top-performing strains” specifically bred for massive yields and heavy resin production, a trend highlighted by platforms like SeedSupreme. Motor Grease sits squarely in that lane, aiming to satisfy both the heady enthusiast and the production-focused cultivator.
Geographically agnostic but culturally in tune with North American preferences, Myers Creek’s design language suggests the curation of fuel-heavy chem, OG, and glue influences tempered with a creamy, confectionary ribbon. That blending often improves user appeal across daytime and evening windows. While exact percentages and parents remain proprietary, the phenotype outcomes and extract performance are consistent enough to have created a quiet, loyal following.
Genetic Lineage and Phenotype Expectations
Motor Grease’s precise lineage is not publicly disclosed, but its behavior and organoleptics strongly hint at a fusion of gas-heavy and glue-forward families. Expect sturdy branching, medium internodal spacing, and a predictable stretch of roughly 1.5–2.0x after the flip to 12/12. Flowers usually stack into baseball-sized clusters with pronounced calyx development by week 6–7 of bloom, tight enough to weigh heavy but not so tight as to invite chronic botrytis when airflow is strong.
Two broad phenotypes commonly show: a fuel-dominant pheno with solvent-shop fumes, pepper, and rubber; and a dessert-gas pheno that folds in cream soda, vanilla wafer, or faint cocoa. The fuel pheno often leans slightly more uplifting in the head while maintaining strong body weight, whereas the dessert gas expression can feel more cocooning, especially when harvested at high amber trichome ratios. Both phenos typically deliver high trichome density and an oily resin character that makes trimming sticky and extraction rewarding.
From a cultivation standpoint, structure suggests compatibility with topping, low-stress training, and screen-of-green layouts. Stems lignify well by mid-veg, supporting substantial cola formation without excessive staking when fans and trellis are well managed. Finicky phenos are rare; most Motor Grease plants perform predictably under conventional indoor parameters and organic or mineral nutrition regimes.
Visual Appearance and Trichome Density
Bag appeal is a Motor Grease calling card. Mature flowers present as compact, weighty nuggets with pronounced calyx swell and minimal stem. Coloration ranges from lime to deep olive, frequently punctuated by aubergine streaks when night temps are nudged 5–10°F lower than day temps in late bloom.
Pistils start pale and peel from the calyxes in long, expressive arcs before turning rust-orange by harvest. Trichome coverage is heavy, with capitate-stalked gland heads that commonly fall in the 70–110 µm range, a size class favored by ice-water hash makers for intact head separation. Sugar leaves often exhibit a frosted, sandblasted look that underscores the cultivar’s extraction appeal.
Under magnification, expect bulbous gland heads to crowd stems so densely that bud contours blur into a uniform, opalescent sheen. This “greasy” finish is not just an aesthetic, it translates into tactile stickiness when breaking buds by hand. On a scale where modern top-shelf hybrids commonly show 1.5–3.0% total terpene content by weight, Motor Grease frequently sits on the upper half of that range when grown and cured properly.
Aroma Development and Scent Notes
Aromatics are unapologetically loud, evolving from raw fuel in early cure to a layered blend of diesel, hot rubber, and spiced cream by week 3–5 in the jar. Open a container and the immediate hit is shop-floor industrial: solvent, axle grease, and scorched pepper. Secondary strata bring black pepper, cracked coriander, and faint pine, likely underpinned by caryophyllene, humulene, and pinene.
As the cure deepens, a soft sweetness peeks through—vanilla bean, malted milk, or even white chocolate shavings. That dessert ribbon is never cloying; it rides behind the gassy spine like a neutral gear catching torque. This duality mirrors aroma patterns familiar to glue-influenced and chem-driven cultivars, in which diesel-gas dominates the fore-nose while a creamy roundness softens the finish.
The “glue” association aligns with terpene data frequently reported in Original Glue (GG4) products, where caryophyllene, limonene, and myrcene are recurrent leaders. Leafly has emphasized that terpenes not only shape smell and taste but may modulate perceived effects, a dynamic readily noticed with Motor Grease’s diesel-calm character. In practice, users often describe a garage-meets-bakery bouquet—strange on paper, addictive in the jar.
Flavor Profile and Consumption Experience
Motor Grease tastes like its name implies: thick, oily, and gassed-up, but with a satin sweetness that rounds off the edges. On the dry pull, anticipate diesel fumes, pepper, and a hint of citrus rind, suggestive of limonene. Combustion adds toasted vanilla and faint caramelization, while a vaporizer at 360–380°F reveals a cleaner, peppered lemon cream.
The mouthfeel is notable, delivering a lingering, almost waxy coat that holds flavor across multiple draws. Exhale is where the rubbery, shop-grease note crests, followed by a cooling finish akin to pine-mint. That sequence—fuel to spice to cream—makes the strain read like a complete chord rather than a single loud note.
Users who favor water pipes report robust expansion, so dosing conservatively at first is smart, especially for newer consumers. Paired with a convection vaporizer, the profile turns more nuanced and less edgy, highlighting citrus-pepper interplay. Sessions often end with a sweet, pastry-like echo that invites repeat sips rather than rapid, heavy pulls.
Cannabinoid Composition and Potency
While exact potency varies by grower, environment, and lab protocol, Motor Grease generally tests in the 20–26% THC range by dry weight under competent cultivation. In legal markets across the U.S., average retail flower THC often benchmarks around 19–21%, positioning Motor Grease above or at the competitive edge of that distribution when dialed. CBD remains low (<1%), consistent with most modern gas-forward hybrids.
COAs for comparable resin-heavy hybrids often show THCA in the 200–280 mg/g range, which decarboxylates to total THC in the low-to-mid 20s after combustion or vaporization. Minor cannabinoids like CBG can land between 2–10 mg/g, and CBC and THCV typically register in the trace-to-low mg/g band. These minors may subtly shape effect tone without driving the overall potency experience.
For edibles, standard decarboxylation at 230–240°F for 35–45 minutes efficiently converts THCA to THC without excessive terpene loss. Extractors working with Motor Grease report robust cannabinoid recovery via hydrocarbon or ethanol, and a terpene retention program can maintain 25–60% of native volatiles depending on process parameters. As always, real-world potency is as much about post-harvest handling as it is about genetics or lighting wattage.
Terpene Profile and Effect Modulation
Terpene output in Motor Grease reliably trends high, with total terpene content commonly landing between 1.5–3.0% of dry flower mass in quality runs. Caryophyllene frequently leads the pack, with limonene and myrcene often close behind, composing a classic gas-spice-citrus triad. Humulene, linalool, ocimene, and pinene appear as secondary contributors that elaborate the profile.
This distribution mirrors patterns seen in glue-dominant and chem-leaning hybrids. Leafly’s coverage of Original Glue underscores that terpene variance is not cosmetic—these volatiles may alter subjective effects even when THC is constant. Caryophyllene’s unique CB2 receptor affinity has been documented in preclinical literature, a pathway plausibly linked to perceived body comfort and reduced edge.
For consumers who detect a dessert accent, limonene’s bright citrus and myrcene’s smoothing bass line echo the terpene framing reported for Cookies and Cream by resources like CannaConnection. That doesn’t assert genetic identity; rather, it highlights overlapping chemotypes that yield a pepper-citrus-cream signature. The net effect is a strain that smells loud, tastes coherent, and feels rounded rather than jagged at comparable THC levels.
Experiential Effects, Onset, and Duration
Inhaled effects typically arrive in 2–5 minutes, peak by 30–60 minutes, and taper over 2–4 hours. The first wave is heady clarity shot through with diesel-fueled focus, followed by a settling body heft that melts shoulder and jaw tension. At moderate doses, many users report a calm, motivated groove suitable for audio work, long walks, or kitchen projects.
Push the dose higher and Motor Grease leans decidedly heavy—sofa gravity, slowed time perception, and couch-friendly contentment. The fuel-forward phenotype trends a bit more alert in the head, while the cream-gas pheno can feel more sedative, especially with later harvests rich in amber trichomes. Regardless of pheno, the strain’s oily terps can make it feel stronger than lab THC numbers suggest, so titration is key.
For oral consumption, onset extends to 45–120 minutes with a longer 4–8 hour arc, and first-timers should start low at 2.5–5 mg THC to assess sensitivity. Combining Motor Grease with caffeine accentuates the focus and reduces perceived heaviness but may increase racy moments in sensitive users. Hydration and pacing help sustain the pleasant middle of the curve without tipping into overconsumption.
Potential Medical Applications and Evidence Base
The 2017 National Academies report concluded there is substantial evidence cannabis is effective for chronic pain in adults and for chemotherapy-induced nausea and vomiting. Motor Grease, with THC commonly in the 20%+ range and caryophyllene-forward terpenes, aligns with profiles many patients use for evening pain relief. Patients often describe a 20–30% subjective reduction in pain intensity at moderate doses, consistent with effect sizes reported across observational cannabis studies, though individual response varies.
For stress and anxiety, limonene’s citrus brightness and myrcene’s soothing backdrop can be supportive, but high-THC strains can be biphasic—calming at low dose, edgy at high. Preclinical studies suggest caryophyllene’s CB2 activity may contribute anti-inflammatory benefits, while limonene has been explored for mood-elevating potential. Such findings remain complementary, not definitive medical claims, and should be integrated with clinician guidance.
Sleep onset and maintenance can improve when Motor Grease is taken after dusk, particularly with later-harvest flowers showing more amber trichomes. Nausea control and appetite stimulation are commonly cited benefits; THC has well-established antiemetic properties leveraged in clinical contexts. As with all cannabis for medical use, starting with low doses, tracking outcomes, and aligning with a healthcare professional are best practices for safety and efficacy.
Comprehensive Cultivation Guide: Environment and Substrate
Motor Grease responds best to stable indoor parameters: daytime 74–80°F (23–27°C), nighttime 68–72°F (20–22°C), and relative humidity at 60–65% in late veg, 50–55% in early flower, and 45–50% by late flower. Target a VPD between 0.9–1.2 kPa in veg and 1.2–1.5 kPa in bloom to maximize stomatal conductance without inviting stress. Good airflow with 0.3–0.7 m/s canopy wind speed reduces microclimates and mitigates botrytis risk on dense colas.
Lighting intensity in veg should deliver 400–700 µmol/m²/s PPFD for 18 hours, transitioning to 900–1200 µmol/m²/s PPFD on a 12/12 schedule in bloom for photoperiod plants. Under enriched CO2 at 1000–1200 ppm, the canopy can exploit up to 1200–1500 µmol/m²/s PPFD if irrigation and nutrition keep pace. Daily Light Integral (DLI) targets of 35–45 mol/m²/day in veg and 40–55 mol/m²/day in flower are appropriate benchmarks.
Substrate flexibility is a strength—high-quality living soil, coco-perlite blends, and rockwool drains can all produce top-shelf flowers. In soil, aim for pH 6.2–6.8; in coco or hydro, keep pH 5.8–6.2 for optimal nutrient availability. Root-zone oxygen is critical, so maintain 20–30% air-filled porosity in soilless blends and avoid overwatering that collapses pore space.
Cultivation Guide: Propagation, Training, and Canopy Management
Germination rates for fresh, reputable seeds commonly hit 90%+ when temperatures are maintained at 75–80°F and media are kept uniformly moist, not saturated. Soak seeds for 12–18 hours until the shell hydrates, then place into starter plugs or lightly amended soil, ensuring good contact. For cloning, 0.3–0.5% IBA gel, 75–85% humidity domes, and mild light (100–200 PPFD) generate 80–95% success in 10–14 days.
Motor Grease enjoys training. Top once at the 4th–6th node, then employ low-stress training to open the center and even the canopy. A single layer of trellis net set 8–12 inches above the pots holds colas upright post-stretch, and aggressive defoliation is unnecessary—selective leaf removal for airflow at weeks 3 and 6 of flower usually suffices.
Veg times of 21–35 days from rooted clone produce 4–9 tops per plant in a 1–5 gallon container, depending on plant count and target yield. Expect a 1.5–2.0x stretch after the flip, enabling close stacking under consistent PPFD. Keep internodes tight by limiting day-night temperature swings to 5–10°F and supplying steady calcium and silicon to strengthen stems.
Cultivation Guide: Nutrition, Irrigation, and Deficiency Management
In coco or drain-to-waste, run EC 1.2–1.6 mS/cm in late veg and 1.8–2.2 mS/cm through mid flower, tapering slightly in the final two weeks if you prefer a leaner finish. In soil, use amended media targeting 150–200 ppm N early, with P and K escalating during bloom to support flower set and density. Maintain a consistent Ca:Mg ratio near 2:1 and aim for 60–80 ppm elemental Ca and 30–40 ppm Mg in solution for coco and hydro regimes.
Irrigate to 10–20% runoff in soilless media to avoid salt accumulation, and verify runoff EC weekly to keep root-zone chemistry stable. Allow pots to dry back to roughly 50–60% of container capacity between feeds to maximize oxygenation; in coco, this can mean 1–2 fertigations per day under high PPFD. In living soil, water to field capacity, allow for full gas exchange, and supplement with top-dressed organic amendments at key stages.
Common issues include calcium-related tip burn at high light if Ca isn’t maintained, and potassium hunger from week 5–7 in heavy feeders. Interveinal chlorosis late in bloom can be normal senescence; earlier onset suggests Mg deficiency or pH drift. A weekly root-zone check—pH, EC, and temperature—prevents most surprises and keeps Motor Grease operating in its happy window.
Cultivation Guide: Flowering, Ripening, and Harvest Metrics
Photoperiod Motor Grease typically finishes in 8–9.5 weeks of 12/12, with many phenotypes sweet-spotting around day 63–67. Trichome monitoring tells the real story: harvest at ~5–10% amber for a brighter, more functional effect, or 15–25% amber if you want maximum body weight. Pistils alone can mislead; rely on trichome heads at 60–100x and overall calyx swell.
Indoor yields of 450–650 g/m² are achievable under 900–1200 µmol/m²/s PPFD with well-managed canopies, CO2, and attentive fertigation. Single-plant outdoor yields often land between 500–1000 g in favorable climates with full-season veg and trellising. Structure lends itself to a uniform canopy with minimal popcorn if light penetration is maintained.
For extraction, Motor Grease’s bulbous heads are promising. Hydrocarbon extraction often returns 18–25% of input mass in total cannabinoids and terpenes, depending on cut and cure. Ice-water hash makers report 3–5% yields from fresh-frozen material on many resin-forward hybrids, with select phenotypes exceeding those marks under dialed wash parameters.
Post-Harvest: Drying, Curing, and Storage
Dry at 60–65°F (15.5–18°C) and 55–62% RH for 10–14 days with steady, gentle airflow that never contacts the flowers directly. Aim for a slow, even dry that drops moisture content to roughly 11–12% before final trim. Stems should snap rather than bend, and small buds should feel dry on the exterior but not brittle.
Cure in airtight glass or food-safe containers at 58–62% RH for 4–8 weeks, burping daily in week one and tapering to weekly as headspace humidity stabilizes. Water activity in the 0.55–0.62 range preserves terpenes while limiting microbial risk. Overly rapid cure volatilizes the very compounds that make Motor Grease special—patience pays dividends in both flavor and smoothness.
For long-term storage, maintain 60–65°F, keep light exposure near zero, and consider nitrogen flushing or vacuum sealing for batches slated for extended hold. Every 10°F reduction in storage temperature roughly halves the rate of oxidative degradation, so cooler is better within reason. Under ideal storage, terpene loss is minimized and the diesel-cream blend remains intact for months.
Outdoor and Autoflower Considerations
Outdoors, Motor Grease appreciates warm days, cool nights, and ample sun, thriving in USDA zones where late-season rains are predictable but manageable with canopy airflow. Planting after soil temps stabilize above 60°F and finishing before the heaviest autumn storms reduces mold pressure. A single topping early in veg and judicious thinning keeps the canopy airy without sacrificing yield potential.
If you encounter an autoflower version from third-party breeders, plan on a swift 8–11 week seed-to-harvest window typical of autos. As Leafly notes, autoflowering plants are hardy and adaptable across climates, making them a practical backyard choice when photoperiod control isn’t feasible. While Myers Creek’s original release trends photoperiod, autos offer a compact alternative for short seasons and stealth grows.
Outdoor feeding can be lighter than indoor—rich organic soils with slow-release inputs can carry plants most of the way. Mulch to moderate soil temperature, conserve moisture, and support microbial activity that unlocks nutrients. Stake early, trellis before storms, and keep a prophylactic IPM cadence to sail through late summer without surprises.
Integrated Pest Management (IPM) for Motor Grease
Dense, resinous flowers always demand proactive IPM. Begin with clean starts and quarantine new clones for at least 10–14 days, inspecting with a 60–100x scope for mites, thrips, and eggs. Maintain sanitation—wipe-downs, foot baths, and dedicated tools—so problems never gain a foothold.
Use a layered approach: beneficial insects like Neoseiulus californicus and Amblyseius swirskii can suppress mites and thrips, while Beauveria bassiana foliar applications in veg provide biological pressure. Rotate modes of action and avoid spraying beyond week 2–3 of flower to preserve trichomes and avoid residues. Canopy airflow and a tidy understory reduce humidity spikes that trigger bud rot.
Scout weekly and log data. Even a simple record—leaf counts of pests per sample, sticky card tallies, and notes on hotspots—boosts response speed and prevents escalation. Motor Grease’s dense tops reward this discipline with clean, market-ready flowers.
Buying Tips, Market Context, and Authenticity
When hunting Motor Grease, verify the breeder—Myers Creek Cannabis Seeds—and check lot numbers or breeder packs for authenticity. Marketplaces like SeedSupreme regularly showcase new, resin-forward cultivars from multiple banks, reflecting broader demand for strains that deliver both volume and quality. While retailers differ, the common thread is a spotlight on heavy-yielding, terp-saturated genetics designed to maximize harvest value.
Given the partial opacity in modern strain genealogies, resources such as SeedFinder catalogue many entries under “unknown lineage,” reminding buyers that brand reputation and performance data matter as much as family trees. Ask for cultivator notes, harvest dates, and post-harvest parameters; these often predict your experience more reliably than names alone. If phenotype variability is a concern, consider buying multiple small samples to zero in on your preferred nose and effect.
For home growers, prioritize stable packs, seek grow logs or journals, and plan space and environment according to the strain’s known stretch and density. If extraction is your goal, request wash tests or rosin yield reports from prior runs when possible. Authentic Motor Grease should deliver unmistakable gas-first aroma layered with spiced cream, plus a tactile, oily resin feel that sticks to scissors.
Context, Comparators, and Sensory Benchmarks
On the sensory map, Motor Grease triangulates between the industrial-diesel punch of chem/OG lines and the softened sweetness of modern dessert hybrids. If you know Original Glue (GG4), you’ll recognize the peppery, limonene-lifted backbone and the way it can feel weighty yet functional at measured doses. Leafly’s reporting on GG4’s terpene composition and effect modulation offers a helpful analogy for understanding why Motor Grease feels both assertive and rounded.
If you’ve explored Cookies and Cream phenotypes, the cream-sugar accent in some Motor Grease cuts will feel familiar. CannaConnection attributes citrusy lift to limonene, pepper to caryophyllene, and relaxation to myrcene in Cookies and Cream, a trio that appears again here in a gas-first framework. That crossover does not prove lineage, but it provides a practical benchmark for tasters.
For yield and resin, Motor Grease belongs with contemporary “new arrivals” bred to be both commercially sound and connoisseur-worthy. As SeedSupreme’s positioning suggests, the market rewards hybrids that combine heavy resin with notable aroma. Motor Grease meets that brief with a profile that reads loud on the table and performs in the garden.
Final Thoughts and Summary
Motor Grease is a modern hybrid that lives up to its name—oily, dense, and unapologetically gassy—with a velvet cream finish that elevates it beyond simple diesel. Bred by Myers Creek Cannabis Seeds and labeled as indica/sativa heritage, it lands in the sweet spot for consumers who want body comfort without losing functional clarity at modest doses. The cultivar’s consistency in bag appeal and extraction performance cements its reputation across both hobby and professional contexts.
Expect a terpene suite led by caryophyllene, limonene, and myrcene, in line with glue-adjacent chemotypes noted by sources like Leafly, with dessert accents reminiscent of Cookies and Cream’s terpene framing described by CannaConnection. Potency commonly sits in the 20–26% THC range when grown under optimized conditions, above typical market averages. Cultivation is straightforward when environment, airflow, and nutrition are dialed, returning 450–650 g/m² indoors with 8–9.5 week finishes.
In a landscape brimming with “new strain” hype, Motor Grease earns its spot with substance: flavor depth, tactile resin, and reliable morphology. Whether you roll it for the diesel-cream duet or wash it for a loud, peppered-gas concentrate, the strain delivers. Treat it with care from root zone to cure, and Motor Grease will reward you with the kind of jar you reach for on repeat.
