Re: Husqvarna 55 fuel mix
Most decent oils mix at a ratio of 50:1, this is dictated by the oil and not by the equipment as many think. Oil has progressed since the 1970s leading to less oil being needed. One oil called Amasoil mixes at 100:1!
I use Stihl oil in a 40:1 mix, I add the extra oil to add a further degree of protection, I know the damage an air leak or lean mix can cause and a little more oil would help in this situation.
A couple of other facts - only mix enough fuel for a day to a weeks cutting as the oil is degraded byt he petrol and also never mix in the tank, always use an external container and mix well. Always drain the tank if the saw is left for a long time - the fuel has a tendency to destroy fuel lines in time.
