Since getting my first chainsaw, I have been only using pre-mixed fuel. Usually 40:1 but sometimes 50:1 if they are out of the 40. When I got my first Husky saw, I used Husky fuel, and when I got my first Stihl saw, I used Stihl fuel. Since then, I have basically just been using whatever is on sale. Whether it is VP, Stihl, Husky, TruFuel, or Powercare. Has anybody noticed any big differences in these fuels? Is it basically the same as going to BP vs Shell, and it's all gas, one isn't better than any other? In all honesty, I have not noticed a difference between running any of these. I would be happy to hear other's thoughts on these brands, or which they prefer and why.
