Default RE: 7.7 running hot

Yea,get some good fuel and let me know.I think that HOMEBREW is overheating your engine.I could be wrong though,but if Im right,lets hope you havent damaged your engine.Is the top of your piston still clean and shinny,or is it dark or black looking.If that piston is the wrong color,then the fuel is crap for sure.Get some good fuel,go back to factory settings and go from there.Good luck
