Hi,

I just purchased a 2004, AUDI A3 with a 2.0L BKD engine, 103kw 140hp, without DFP. 168 000 miles.

The old owner, who had the car for around 8 years, always used 10w40 505.00 oil while the car manual says it needs 505.01 or 507.00.

My question is, should I swipe to 505.01 from now on or it's safer for the engine to keep using 10w40 505.00?

Btw, this case shows a car can run eight years on a non specified oil!

Hi

I would switch to the recommended oil.

It's like driving on a bad alignment....you can do it but it eats up tires ....
I was just using that as an analogy.
