HELLO AGAIN EVERYONE

 

i,ve been mullng over in my head etc the advantage of fully synthetic 2 stroke oil as if it would be the differance of longevity & semi seize or not seize if i had been using semi 2 stroke at £22 for 5lts or £32 for full synthetic as i,am lucky to have a oil refinery on my doorstep so have a choice of many oils to choose etc as they blend all there own oils and have done so for years caldo oils st helens

 

whats your views please as i can pass this knowlage onto my good friend sean who makes his living same as you boys on here etc"" and has an amoury of saws strimmers etc etc so lots of 2 stroke oil used etc

 

ps i will see if they do semi syn chain oil too but not sure if its option and its pro,s n cons costs etc
