A couple years ago, epa changed ethanol amounts in certain states. My state of Rhode Island was not listed.
Yesterday, a customer came in with his little used 4 month old Stihl 261 with a hole in the piston. He said it started screaming and then just shut down. The cylinder wall was scored along with the hole in the piston..
So we tested his fuel mix. It came back with 16% ethanol.
Places like 7/11, Safeway, Stop and Shop gas stations have been getting ethanol 15 without notice to the general public.
Shell and Mobil maintain 10%.
If you are mixing your own fuel for 2 cycle engines, check to see if your state is allowing E-15 at second tier gas stations.
Stihl covered the customers saw under warrantee seeing it wasn’t his fault that he didn’t know his purchase was E-15.
I think no one knows in my state.

Logic can see no reason why E15 would hole a piston!

But an air leak will.

The cylinder studs on my husky came loose last fall. It's a good thing I recognize lean running when I hear it.

15 minutes to tighten four studs, and the saw is just fine today!

I just buy the no ethanol 100% gas for mine, in Missouri that's 91 octane.
