fuel cleaner
 

I have 02 bmw x5 with 40,000 miles, what brand of fuel cleaner do u recommend. Thanks guys...

I use something claeed sr1-redline, I am not sure what its called. Its a Autozone, $7. It says its approved by BMW on the back of the bottle. It works really well.

At 40K, I would recommend just dumping a bottle or 2 of Techron Concentrate right before a oil change.

Redline is good stuff as well, just not easily available.

Techron can be found in most auto stores.

BMW sells one at the dealer.
