Hi All,
I'm about to do an engine oil change on my EK4 Civic.
I've been reading up a lot on what's the best, etc.
I believe Royal Purple Full Synthetic is one of the best on the market. Does anyone know i can get this stuff?
Oh, and what VISCOSITY do people recommend?
Factory for me is 10-30, i think. but i wanna change to 10-40 at least.
Any advice (especially technical with proof) would be greatly appreciated.
Thanx
Chris
