    Question What fuel injector cleaner to buy?

    Should I buy Redline Si-1 injector & valve cleaner? Lubro-moly injector cleaner? Some Techron stuff at the local store? What kind should I get, and where? Thanks in advance.

    I met with the president of the company last week and I tried the stuff in my 528e. It seems to work great.

    I've heard (and experienced) nothing but good about the Techron and the RedLine.
    I used the RedLine shortly after I bought my 318 (86K mi) and it noticeably smoothed out the idle and throttle response. The previous owner had used "discount" gas. Before, blipping the throttle in neutral produced a little stumble. Now it is perfectly clean.
    Adding the Redline produced no difference in my other vehicles, but I used Chevron gasoline (with Techron already in it) at least 75% of the time in them, so I guess the Techron worked equally well.

    How funny you should post this - I put Chevron Techron FICleaner in my car today! 20 oz bottle was like $12 or something at Advance Auto Parts... It says 20 oz = 20 gallons of fuel, so I went with about half.

    Seems to work great... car seemed to be going smoother as I drove around tonight. Whatever product you choose should do a pretty good job... IMHO at least!
