Engine oil Shell or RED LINE

Shell Engine oil

Can’t go wrong with Rotella T6. It’s marketed as a diesel engine oil, but gas engines love the stuff too. It’s just not great for catalytic converters, because it contains a high amount of anti-wear and anti-friction additives.

Pros: gas engines love it
Cons: bad for catalytic converters
Vehicle: BMW

Oil consumption was the biggest issue when running 5w30. Changed to a 5w40, 10w30, and then got recommend 15w40 and oil consumption stopped

Pros: stopped oil consumption
Vehicle: Subaru
Mileage: 363000 km

Shell Engine oil

I think factory recommendation is Rotella but honestly you can go with any high quality oil. I have used Rotella, Castrol, and Valvoline synthetics in my 500 and I honestly don’t think it matters.

Pros: high quality oil
Cons: doesn’t think it matters
