Valvoline Motor Oil, 10W-40, 1 QT Pack of 2 | Full Synthetic | 4-Stroke Motorcycle

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 for my yamaha fz-07

I means it’s oil for a 4 Stroke it works just fine for my hawk 250 no issues unless you just don’t get the difference between 4 stroke or 2 stroke the. You might have a problem with this oil but works just fine quality perfect and it last very long

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。
