I can't beieve how well this stuff works! I got it at Wal Mart! It costs $5, which is why I never bought it before. I figured the extra money was for the Chevron name. That STP stuff is crap! There must be a catch, does it ruin spark plugs or something?

No catch.My best friend works at a GM dealership (service dept).He says GM recommends this stuff and that they use it at their shop.The fuel system cleaner is also very good,burns up all the carbon off valves, etc.
He recommends dumping a bottle in my car every month.I have done this, and have had no fuel injection problems in over 225,000 miles in my f-body and 210,000 miles in my S10
Blazer.
