Got all the parts to service my Coupe Turbo. Just forgot what oil I need and after trying to search, I got even more confused.
Engine was rebuilt 14k miles ago. Z20LET running 240bhp.
I know I need 10w/40 grade Oil. Does it matter if it's Fully Synthetic, Semi-Synthetic or whatever?
Castrol 10/40 is on offer at my local shop, but doesn't say if it's Fully Synthetic or Semi-Synthetic? So not sure what it is?
Oils are confusing for my little head.
