So when I first started out and never could get my buggy to run I was using byron once I switched to vp powermaster everything turned around now I'm out of fuel run to the store all that's left is byron I figured what the hell got a quart mixed with the little bit that was left in my tank it started 2nd pull like always ran then died after take off now I'm back to a non running buggy thanks to byron fuels I effing hate there fuel I don't care what people say it its junk. I've tuned the hell out of it and nothing I do will make it run with that fuel
