Chainsaw Repair

I just buy regular at the gas station.Never had any trouble. Keeps OK over the winter etc.

Amsoil at 100:1 is a no no.

But not at 100:1.

There's not enough oil there to cover the error margin. Amsoil has a lot of antiwear additives besides synthetic oil in the formula.

If you are a prolific chainsaw runner and you keep the bar buried all day, you will soon gall a piston. And the guy that tears the engine down will immediately see the lack of oil on the piston. I have a Dolmar here that a guy ran on Amway 100:1 and I have the galled piston and cylinder to prove what happens.

If you are compelled to use Amsoil, use it with a more realistic oil ratio like 50:1

+1

Is it just me, or do others think that of late it`s become a peeing contest as to who can use the LEAST amount of oil in the premix, in my fairly long motorcycle road racing[ 30+years] career a good part of that time with 2 strokes, the 3 different tuners of my bikes all said the same thing. More oil[within reason]= more power, to quote a point my RS125 Honda at 40-1 produced 44BHP at the rear wheel @ 12800rpm  At 30-1 it worked out @45.6BHP@ 13200rpm this was using Castrol A747 syn oil. Now I know we are talking different type engines [but they have the same basic operating system, requiring oil/fuel mix for lubrication] so in my opinion this holds good in all types of 2 stroke motors, surely saving a few pence/cents on less oil in each fuel mix is not worth losing the piece of mind + maybe the additional cost of piston & cylinder & possibly worse by going less on the lubrication I have chainsaws dating from 1967 /2006 & never run less than 32-1[ Stands back & awaits incoming]
