I have a 20 year old Homelite trimmer that won't die! It takes 32:1 gas/oil mix and to simplify my fuels I was thinking of using the Stihl synthetic oil which is a 50:1 mix(I have a couple Stihls in the fleet) in my Homelite. Will this be safe to do? The guy at my local OPE shop said the Stihl 50:1 mix would protect the Homelite better then using other oils mixes at 32:1 as the Stihl oil is such good quality. What do you guys think? I never use up the fuel I mix and end up waisting a lot of it so the less fuel I mix up the better. Many thanks!
