I did use the really old n tired 026 to rip a ring in half but that was rather painfully slow by comparison... That got another good sharpen when I got home. Fueling car at Z earlier,I'm looking at the 100 octane petrol,might just have to give it a whirl as the BP 98 always made smaller motors sing. Even a 50/50 mix giving me a 95ish octane might be worth a crack.big pile of rings to be split now that is for sure.

Stick with 91 octane, anything higher won’t make a chainsaw run better unless it’s modified compression ratio demands it.

Stock saws will run better with 91 octane as it contains a gnats willy more energy than higher Octane fuels.


A misconception that high octane fuels contain more energy is common, they don’t, they just ignite and burn slightly slower in high compression situations to protect high comp engines from detonation or “ pinking”


Best thing you can do for a saw is keep it extremely sharp and run the best bar oil you can find, and use it properly with an unrestricted exhaust
