Recommended Engine Oil For 1999 A6 2.8 With 90k

I'm Using Synthetic Mobil 1 5w-50 but I think it's making my car mildly overheat, too thin for the mileage that my car has I guess. What do you guys think?

ps if your car is overheating, check out your cooling system. you might need a good flush.

5w-30, 10w-30. I wouldn't bother with a synthetic on an NA engine.

It will tell you in your owner's manual....

I just did my saturday with Castrol 5w-40 (fully synthetic)

That's what the manual recommended and if 5w-40 was not available to use 5w-30.

The owner's manual said it came stock with 5w-40.
