I'm not criticizing, but I've never blown up a saw either, and I've never run 32:1.
The metric system makes mixing easier. Only problem is that the U.S. Gallon is different than a metric gallon.
One litre of mix will make 50 litres of gas @ 50:1
One litre of mix will make 40 litres of gas@ 40:1
One litre of mix will make 30 litres of gas @ 30:1
It must be some kinda cult.what the hell is metric
Now I know why all my saws are scored! They have been fibbing to us!Actually would 51, 41, and 31 liters, respectively. Otherwise the mixes would be 49:1, 39:1, and 29:1
32:1 is all I run now.Another vote for 32:1 for everything ive ever ran and tuned correctly, ive NEVER had an issue with killing a saw. Except for an old Poulan that wouldn't stand up to being run over by my dumptruck

There is a trade-off, as you add oil to the mix. No matter what some folks want to believe, oil is not burned off as it departs a 2-stroke Otto-cycle engine. It's vaporized into a nasty mix of POM- polycyclic organic matter, much of which is carcinogenic. (That's not good.)
Take a look at the air-quality you see during broadcast of the Indian Grand Prix. They have huge #s of mopeds, tuk-tuks, and other 2-stroke-powered vehicles in India, and the broiled oil they disperse can be easily seen in the air. Our 2-strokes are not immune from that, and it's got to go somewhere for a while.
The POM concentration is in direct proportion to the percent of oil in the mix. That's one reason I don't go beyond 40:1.
Remember the Good Old Days of 16:1?
