engine oil to use ?

[geoffinbc]

Yup an standard 5W30 or 10W30 multi grade oil will work fine. No real need to get fancy or anything that is just up to personal preference

I don't care what anyone says, i still use Royal Purple in mine.



the daily driver gets mobil1 though.

Not familiar with that type but castrol should be fine.

Hello everyone who I could say if the MAGNATEC Castrol 5W-30 is good for the performance GM engine ? Thanks best Regards Francesco
