Morgan Fuel Sidewinder RaceBlend 30%(4)HAZ

Ordered this a few years ago and it seemed ok initially. Recently I tried running it again, and the lubrication was very poor and caused some damage to the engines I ran it it. My os.18tz would actually lock up after it cooled down. So I pulled the head and found a sticky film all in the sleeve and on top of the piston. I did more research on this fuel and most people said they also had issues. It’s garbage fuel. I bought 12qts of bones brew recently and it’s much much better. No more problems. The engines all seem well lubricated now and that’s with only 8% oil content in the new fuel
