Valvoline 4-Stroke Motorcycle Full Synthetic 20W-50 Motor Oil 1 Quart

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,

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.

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.

Very awesome

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

My motorcycles shift better than with Amsoil or Motul 7100. Especially my ninja ZX6. And it's cheaper although not as cheap as it used to be.

Was using an oil that is twice the cost of Valvoline. When I put Valvoline 10w40 in my 2025 Goldwing Anniversary it was noticably quieter and Runs smoother. Will use this oil from now on.
