I switched to Castrol Edge 5w40, and what a difference! It loves it. We didn’t lose any fuel mileage, just as Pepe. but much much smoother.

Pros: much smoother, no fuel mileage loss

Any 5w30 that’s c2 or c3 rated will do, that said I’ve heard negative reviews around the quality of castrol so maybe spend just a little bit extra and get something mid range, I use Fuchs Titan GT1 FLEX C23 5w-30.

Cons: negative reviews around quality
