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

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 for my yamaha fz-07

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.

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.

Great synthetic oil

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

good value

Made my scooter run smooth and the full synthetic will be great for my hot weather conditions.

他社の15-50Wを使用していましたが、オイル漏れやオイル減りが激しく、試しにこちらを使用したらほぼ止まりました。ギアチェンジもスムーズです。

Good quality oil.

ペンズの20-40Wを4L缶で最初買いましたが、ギアチェンジが無茶苦茶硬くなり失敗し、このオイルに変えたところスムーズに動くようになりました。ま、相性でしょうがね。お勧めします。
