I, too, have been really impressed with Sidewinder fuel. I used Blue Thunder Sport 20% for the last couple years and then tried a gallon of Sidewinder Backyard basher 20% w/16% oil and what a difference. Truck ran smoother, cooler, with more power. I have now cracked open a gallon of 30% Race (12% oil) for my modded 3.3 and WOW...if you haven't tried 30% fuel your missing some serious fun! I will be buying a gallon of the 20%/12% oil to run in my stock 3.3 very soon. Great fuel and I love that it has ARO already in the mixture.
