I got about 4500 miles on my 02 TLS and got my first oil change done as well. Just wanted to know how often should I put fuel injector cleaner in my TLS. My other cars I used to put a bottle at every oil change but since my car is still new when should I start putting the cleaner in my car.

Well, IMO as we must use premium, and most premium gasses have detergents, I haven't ever done that. I had 28k miles on my CLS and it had the same power if not better than day 1.

When I went to my local dealer to do the 15k checkup they automatically added the fuel injector fluid in. I plan on adding it in every 15k miles just ot be safe.
