Hey guys i was looking through the FAQ's and you guys said synthetic oil was ok, however the guy i brought my car off told me the oil injection system isnt ment for synthetic and it makes the car run real choppy is that a common problem? Id like to run the better oil in it but havent been game to try it

 

Big debate issue. But basically synthetic is ok if you use a good one like the ones in the FAQ. Others will leave deposits and shrink your seals. Again, lots of people believe all synthetics are bad for your '7, so you'll hear it a lot. And the owner's manual says no synthetics. But really there are just a lot of bad ones that cause problems, not all synthetics will.

 

Thanks for the info, think i might just stick to the normal oil to be on the safe side anyway

 

huh?
