Just found out from my dealer that all the echo redmax shindawa and I'm Sure stihl is to. There brands of oil are now going to come in 2.5 gallon mix instead of 2 gallon. Know going to have to mix all my fuel mix in 5 gallon can then poor into my 2 gallon cans. As if the EPA hasn't done enough stupid things. If it's not broke don't fix it.
