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。

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。

I bought a pack of 4 for under $20 and can't complain! I wish I would've bought more while they were on sale. Perfect timing for the upcoming oil change on my yamaha virago. I use valavoline on my vehicles and never have issues with oil quality and wear on my motors.
