チューニングカーのオイルって何が良いの？【イシザキの勝手にオイル紹介！】

There are many different opinions about oil, so I've summarized my own. I hope you'll consider this as one opinion. The reason I use Royal Purple is because it protects the engine and has a long life. Gear oil is also good, but there are some aspects that I haven't fully tested yet, so this video focuses on engine oil. ・Find Ishizaki here!! Twitter⇨@0715hashiriya Email⇨[email protected]
