At 0.225% it will not do that ever.
Some people have experimented with car fuel lines and carby parts and soaked them in pure acetone for weeks with no ill effect.
A fuel hose that has decomposed liquified and glued to the bottom of the tank will dissolve in any other solvent too, including petrol.
I thought the oil ratio was more down to the oil you use than the engine it is used on. I am using stihl oil at 40:1 on all my 2 stroke machinery including 045 and 056 that used to run on 20:1 with the oil available in the eighties. I don't use them often enough to be sure, so someone please let me know if I am on the wrong track before the old stuff gets toasted.
