Engine oil Shell or OEM Audi

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

OEM Audi Engine oil

On my 1.8ts I usually change it when the motor blows up and has to be replaced. They used to last perpetually but builds have progressed to the "Yes it absolutely is going to grenade or window the block before 10k miles???? so really I only ever have to FILL oil 1 time???? I wish this was less true than it actually is. On the rest, (2.7tt and 4.2) 10k miles if you use good full synthetic oil and a nice filter

Pros: 10k miles with good oil
Cons: engines blow up before 10k
Mileage: 10000 km

Stay away from rotella conventional. I’ve heard and now as well personally have had a turbo grenade due to their oil quality, that’s the conventional anyways.

Cons: turbo grenade
