ProHonda oil HP4S

[Sadorphan]

I just run motul 7100 10w40, its cheaper than the 10w30 and runs the same. Motul is known for being the absolute pinnacle of oils in high level racing. It costs just 10 bucks more than any other synthetic. Sure there is any other synthetic but motul has a incredibly long history of performance liquids/maintenance products. Amsoil also has a equal reputation and is what my previous owner was using based on the amsoil badges on my cam covers.
