I originally bought a gallon of the Wildcat Eliminator 20/14%. Once I ran out of (and got tired of paying high prices for) Top Fuel 20%, I switched over to Wildcat. Richened it slightly, and it seemed to work fine. I ran into engine troubles but it wasn't the fuel's fault (Traxxas verified and replaced the defective piston and sleeve). I switched to Trinity Monster HP just to rule out bad fuel, but the Wildcat was not the cause and it runs just as good on the Trinity as it did on the Wildcat.
Unfortunately, no places local to me have O'Donnell or Byrons, or else Id use them. Wildcat and Trinity Monster HP can both be had within 5 miles of my home, so I use them.
I dont know how long I can let this stuff sit, but if the Wildcat is still "good", I might change back because of the slightly higher oil content than Monster HP (14% vs 12%).
