First off, I'm a lifetime Amsoil dealer (full disclosure).
Bought a brand new Stihl KM-110-R engine (for trimmer and edger and more..)
All tests done with a totally emptied and refilled fuel tank, from a fresh, uncontaminated batch of mix according to Stihl directions.
All gas mix was done with Shell Premium Gas, purchased new at the pump and not mixed with other gas.
Mixing Amsoil 2-cycle oil with premium gas, very rough idle and hard to start. Mixing the Stihl 2-cycle oil at same measurement, pretty good, stable idle, does not stall engine.
Using Home Depot purchased Truefuel 50:1 - the absolute best easy start, easy and steady idle.
Wish Trufuel wasn't so expensive, alas, that's the result ;(
