great oil
Size: 1 Gallon
This oil exceeded my expectations. My engine runs noticeably smoother after switching to it, and it feels like it performs great across different conditions. The quality is solid, and you can tell it’s made for performance. I also really liked the cap design—it made pouring clean and easy with no mess. Definitely a great choice for motorcycles and other small engines. I’ll be buying this again! ... show more

AMAZING OIL..better than Motul 7100 and Maxima Pro plus+ !
Size: 1 Gallon
Running this in my 2026 Honda CB650r..absolutely love it..the best motorcycle oil ive ever used in a street bike, hands down. Previously was using Motul 7100, which was okay but in this hot Alabama summer, seemed to shear off too quickly (lasted less than half of Honda's recommended oil change interval) and rough shifting and high temps, but this much cheaper TRIAX literally improved in every aspect. Highly recommend for anyone needing an oil for an high revving inline 4 street bike. TRIAX has earned itself a new loyal customer!! ... show more

Good Atv oil
Size: 1 Gallon
Seens to be a goid oil in my 2023 Suzuki King Quad 750, and my 2025 CFMOTO Cforce 1000 touring. I don't know this Motors running any quieter but have had no problem with the wet clutch in the Suzuki and oil is doing what it should be doing

Great for wet clutch, good performance!
Size: 1 Gallon
Of the brands of oil I've tried, this one seems to keep my atv engine running cool and it even sounds better. The gears shift smoothly, the clutch engages well and my atv even seems to start more easily. So far I'm pleasantly surprised with the overall performance of this oil.
