GM Fuel System Treatment Plus

88865595 $13.99

We recommend using this for any car with over 50k miles on the injectors. It restores the original spray pattern increasing fuel economy and brings all the injectors back to their original flow rates. This can eliminate KR if you have a single injector that is weak and increase the safety of a high performance setup.

Add one 12 ounce bottle to a full tank for best results.

MPG INCREASE

I had really bad performance issues after my tu ne. Used a bottle of fuel treatment & started getting better results after running out 1/2 a tank. Blew out small amounts of black smoke from my exhaust. Now my engine idles & runs really smooth. Car runs much stronger now. I was getting a knock code before & now it's gone. Gained +2-3 mpg & it's still going up a little. Overall it's a good product & I differently recommend this it with a smile. :grin:
