Scot........I've had great luck with the stuff...........been using it for a LONG time and used LOTS of it........and have never had any problems.........Maybe it's different in different parts of the country???.......I've even run in it in a 15 to 1 572 that ran high 9's, back to back at the race track, against race gas and saw ZERO 60 foot, ET, or MPH difference........
