Mine will wear-out before they ever come close to blowing up.

I actually love those 400's. Use them all day and they don't beat you up, fantastic control in use ands little work horse. Not fond of the people in charge at Echo.
Never have blown anything up ever running 40:1. Never... Mfgs like to sell parts and recommend 50:1. Or never blow anything up ever running 40:1. Ill stick with my mixture. Mfg can keep theres.... Ethanol free gas as well.

I remember when all there was just leaded gas and 16:1. Never had any problems with saws going out of course unleaded rolled around and still didn't have any problems, just carbon buildup. Now it's watered down gas, cheap manufactured parts and not real oil.

Not had any blow up because of the mix, straight gassed yes and air leaks sure. I get some extremely high hour saws running 50:1 and the piston looks great. Maintenance is the key.
Never blown up a saw. My old 65 didn't have much compression left though. Run 40:1 in smaller saws and 32:1 in the bigger ones.
Blown up a few snowmobiles. Can buy a nice pro saw for what it costs to repair them.

But you're saving the environment with your sacrifice.

haha you should add year-old fuel to your list of options for why your saw melted down. Probly kills 10x more 2strokes than straight gas/poor mix ratios.

In 6 years of professional work I've only lost 1 saw, a 360 that had a TON of hours (was used as a sawmill with 38" bar before I got it. It cut enough lumber to build a 2 story house). Lost a crank bearing. Race came apart at idle and locked it up.
It still lives, just put a few new parts is all.
Well... and a beautiful ported 460 that I ran over with a ~70,000lb Komastu 220LC3 stroke delimber, but that doesn't count!
I run 50:1 in all my stuff.

I run strictly 40:1. No fancy oil, just tsc store brand stuff and 93 octane. Haven't lost a small 2 stroke yet. Lost plenty of sled motors though. Always due to lean out not to oil.
IMO failures due to oil type or mix ratio are rare. No oil at all definitely happens though.

The wind blows em down and I cut em up
40:1 stihl brand oil out of the little containers at Fleet + Farm. They had just switched and become a Stihl dealer. I figured what could it matter? Saw did not last 5 minutes.

One of those curly ears broke off one of the wrist pin retainers. Had nothing to do with the oil. Kinda weird though.
