Valvoline 4-Stroke Motorcycle Full Synthetic 10W-40 Motor Oil 1 Quart

This oil is great! My motorcycle sounded like it was at wits end when I first bought it, and it was apparent why. The old oil looked like slightly less viscous sludge. The new oil significantly reduced the vibration, noise, and it works amazing on motorcycles that are manual as it doesn’t have any additives causing the clutch to slip. Shifts awesome now. Valvoline has always been my go to for oil I inspected the pistons after running it for 100 miles and I noticed less carbon which is always nice. Overall great protection, and a great fit for my bike.

Inexpensive. Good quality for our 4 wheeler

I trust this oil for my motorcycles and IMO it is the best quality available. I have been using it for years and have never had any oil related issues.

Great choice for the oil, cost lease,

My bike runs smoother, shifts feel cleaner, and it even seems to start easier. The engine sounds quieter too, which says a lot for an older bike like mine. I’ve put a few hundred miles on it so far and it’s holding up great — no burning, no leaks, just solid performance. For the price, you really can’t go wrong. Definitely sticking with this from now on.

Perfect for motorcycles

Used on my DRZ 400 since the OEM oil is not fully synthetic, great quality and price. Make sure you're using fully synthetic oil in 2025.

Works without issue, had to buy 2 of these for my bike.
