I hear alot on this site about various types of fuel additives. I have not heard anyone mention GMs own factory additive. What do you guys think of GM current additive. I own a auto shop, and could get it by the case at a wholesale price. Just wondering if its as good as the others I hear of here. THANKS!!

Waste of $$. Stick with the pro's

Standyne seems to work the best for me. I found out after I started running it that it is, I believe, even GM approved. Now that it is warmer I just add a couple gallons of B100 to each tank. That works even better than additive.

Moved to supplements and additives.

I run Standyne it is the only one approved by GM. I can tell the difference when I am not running it. It just runs quieter and smoother. piece of mind for me
