I have a 2006 A3 with 138k on it and would like some advice on what fuel injectors can be used on the A3. I was thinking of using the redline cleaner that is available at crappy tire. Any thoughts ?

 

I used a fuel injector cleaner from the Audi dealer. It was under ten dollars. A couple of people have told me to use fuel injector cleaner only if it is clearly needed. I believe the harsh chemicals in the cleaner may cause damage if used frequently. You can try switching gas. Audi recommends top tier gas (Top Tier Gasoline).

 

Motul.. Thats all I use.. I noticed a huge difference.. After oil change
