Motorbreath (sometimes called Motorbreath 15) got its name from its intense diesel aroma and flavor. But lyrics from Metallica’s song of the same name referring to “life in the fast lane,” “full speed” and “taking your breath away” are just as apt.

This powerhouse of a strain is a 70/30 indica-dominant hybrid with a THC content that averages 25%, so it’s not for the faint of heart (or inexperienced smokers). That potency isn’t surprising once you learn that Motorbreath’s parents were Chemdawg and SFV OG Kush and that it was named “best recreational hybrid” at the 2015 THC Championship.

This weed combines uplifting euphoria with a numbing, often-sedative body high that leaves users stuck on the couch and likely to doze off. As for the sensory experience? It’s heavily diesel, with elements of earth, garlic, citrus, and herbs — an enticing mix that screams: “I’m weed! Smoke me!”

Effects and Side Effects

Light tingles announce the arrival of Motorbreath’s THC in the brain — and the start of an experience that is likely to, as Metallica said, take your breath away.

The tingling doesn’t last long, as it’s replaced by a wave of cerebral tranquility that washes away stress and negative thoughts in a flash. The head high also provides some uplifting euphoria, but it’s more likely to be gentle than overpowering. The overall effect is one of calm mental relaxation rather than a surge of energy or creativity. In two words: complete comfort.

It’s not just the brain that feels relaxed, of course, since Motorbreath is an indica-dominant strain. Muscles loosen and relax as the full body stone takes effect and urges users to find a comfortable spot to rest. Not everyone finds themselves glued to the couch for the duration, but more than a few tokes will certainly increase the chances.

If there’s something to do (like watching that new show on Netflix), the experience can lead to an incredibly happy and pleasant stoned evening. Otherwise, full sedation and sleep are a distinct possibility. Motorbreath is a strain to be enjoyed in the evening, not earlier in the day when you intend to get something accomplished.

This weed’s sky-high THC level is one of the highest THC strains and is a flashing warning sign for inexperienced users and those who are already dealing with diagnosed anxiety issues. They are at risk of dizziness, increased anxiety, panic attacks, or paranoia and should either start by microdosing Motorbreath — or avoid it until they’ve increased their tolerance and can handle killer strains.

Dry mouth and dry eyes are more common side effects. Oh, and definitely expect the munchies to hit.

Positive Effects:

  • Energy: 2/5
  • Creative: 1/5
  • Pain: 5/5
  • Stress: 5/5
  • Sleep: 4/5

Negative Effects:

  • Paranoid: 3/5
  • Dry Mouth: 4/5
  • Dry Eyes: 4/5
  • Lethargy: 5/5
  • Cough: 3/5

Bottom Line: Motorbreath doesn’t fool around, delivering a calm but euphoric head high followed by an intense body stone that’s fully relaxing, lethargic, and often sedating.

Medical Conditions

MMJ patients in search of all types of relief love the effects of this strain.

They say that Motorbreath’s stress-relieving head high is ideal for helping them deal with commonly-diagnosed mental conditions like stress and depression. Patients with less common issues like OCD and PTSD also like the strain for its ability to prevent recurring negative thoughts or images.

On the physical side of things, patients use the body-numbing effects of Motorbreath to wipe away the chronic or serious pain they feel from conditions like arthritis and fibromyalgia, as well as everyday aches and sore muscles. The strain is also said to help with migraines, and its sedating effects are valued by people dealing with insomnia and sleep difficulties.

Flavor and Aroma

Saying that Motorbreath’s scent and taste are “strong,” “potent” or “intense” isn’t doing this strain justice. The diesel influence is overwhelming — which might be a very good thing since it might scare away inexperienced users who aren’t ready to brave this weed.

Motorbreath isn’t completely fuel-based, of course. Once you spark up, you’ll notice citrus, earth, garlic, and herbs in both the aroma and flavor of the bud, creating a much more interesting experience than the initial diesel blast might promise.

Make no mistake, though. Motorbreath may be the gassiest weed you’ve ever smoked.

Flavor and Aroma Ratings:

  • Earthy: 4/5
  • Citrus: 3/5
  • Fruity: 1/5
  • Spice: 4/5
  • Wood: 3/5

Cannabinoids and Terpenes

All you need to know about Motorbreath’s THC power is one number: 25%. That’s the average level of the cannabinoid in samples that have been tested by one lab; another has found the average THC content to be even higher, at 28%. THC isn’t the only factor in weed’s potency, of course, but you’d be hard-pressed to find a stronger flower at a dispensary.

There are small but measurable amounts of CBD and CBG in this strain as well.

The terpenes that combine to create Motorbreath’s diesel scent and flavor are myrcene, caryophyllene, limonene, and Pinene, all of which are present in high amounts. Camphene, phellandrene, and other terpenes are in the mix as well.


The secretive but prolific breeder Pisces Genetics developed Motorbreath by crossing two venerable strains, Chemdawg and SFV OG Kush. (Some believe one parent was Chem D, an even stronger phenotype than Chemdawg.)

Chemdawg contributes its notorious potency, powerful head high, and pungency to Motorbreath, while SFV OG Kush adds its high potency, strong physical relaxation, and citrus flavor. It’s a marriage made in stoner heaven.

Where to Buy Motorbreath Seeds

Feminized Motorbreath seeds aren’t the easiest to find, but if you poke around, you can find some vendors that sell them. Try checking with Pacific Seed Bank, Sunwest Genetics, or Sonoma Seeds. If you prefer to grow with clones, Homegrown Nursery says they have Motorbreath clones available.

Similar Strains

If you love diesel strains, you might want to try Sour Diesel or Chemdawg for a great daytime high, or Death Star or GG4 (Gorilla Glue) strain if you want a weed that will put you on the couch. Other options to consider instead of Motorbreath include Purple Thai, Billy Kimber OG, or for equivalent THC content, Bonkers.

Motorbreath Strain Review: FAQ

A: Very much so. The average THC content of Motorbreath has been measured at 25%, but other labs have found it to be 28% – and remember, that’s just an average, meaning some samples were noticeably higher. Be careful with this weed.

Q: Does Motorbreath produce large harvests?
A: We’d call them medium-sized. Indoor grows will yield around 14 ounces per square yard of flower, while outdoor plants should give you about 14-16 ounces per plant.
