It's about time for changing my oil for my 99 A6 Quattro 2.8L. The car is automatic with the tiptronic. Any suggestions as to what type of oil to use?

Also, I need some power steering fluid. Any suggestions for that?

Thanks for the help!

 

i use 5w40 mobile one syn. i have the same car as you. i also have to change the psf and will be using pentosin from ecstuning when i get around to it.

 

are you just changing the engine oil? If so use a good quality regular motor oil or synthetic blend. I imagine that your car has over 100k since it is a 99. I would use 10-30 or 10-40 in it if it was me.

As for PS fluid, only use audi Pentosin fluid. Get it from the dealer or from ECS.

 

i ran my 99 a6 2.8 to over 188k before i sold it. Always ran mobile 1 15w50 performance oil. It is much better for the engine in my opinion. I ran it in new england winters and never had a problem. Whatever you pick stick with synthetic, it doesnt break down like conventional!
