Engine oil AMSOIL or OEM Honda

0W-20 Amsoil Signature Series 100% synthetic oil changed every 5k miles. Wix 57173XP filter.

As an avid user of AMSOIL, it’s a noticeable difference, amsoil is the king

With Amsoil even if it's not signature series I trust it more than any other 0w8.

I run Amsoil and my oil change interval is 25k so the answer is it depends.

I only use Amsoil Signature Series in my B58.

I changed to that and really happy with it so far, shifting is butter smooth.

Só uso óleo Honda original do meu, e mineral. Depois que li o manual e vi um aviso gigantesco falando pra usar apenas ele, nunca mais cogitei trocar kkkkk

Based on my own tests, I found the AmsOil to be the best at reducing heat a few degrees. It's not cheap, but it's still cheap insurance, all things considered.

Got a call this morning from him and he said that the gasket/seal for the oil filter housing where it connects to block is leaking oil.

personally, I think Amsoil AFL is junk. They ruined a stout oil when they reformulated it to mimick 505.01.
