Chainsaw Repair

I talked to Bob he runs all his saws on LL100. So I bought 5 gals of it and mixed it 40 to 1. I tell you my 1990 262 xp I can tell a big diff in it as well as my dolmar.  I was pulling my hair out snice last fall when the shell gas dealer sold out. They had unblended 93 I ran in every saw I own. Check every gas station around for 50 miles all 91 mutiblended not straight blend. Besides anyway LL 100 has a good shelf life vs std pump gas.I know that for a fact. Tell you one thing it smells strange..lol.
