When new Homelite called for a preferred mix of 32 to 1 with the special "Homelite" oil. Also allowed 20 to 1 with standard SAE oil, just like Stihl did at that time.
The reality is - if you've got a good air-cooled rated oil, you can run 20-1, or 25-1, or 32-1 in just about anything and be fine - as long as the saw has an adjustable carb. Many newer saws do not and if you use too much oil, you get a lean mixture. Too much oil can plug up some spart arrestors also.
I've got saws over 50 years old and some only 1 year old. I use 20-1 in all to keep things simple. It's also cheap insurance. Oil lube had not improved as much as some people like to think. Many of the new low-oil mixes have emissions in mind. Not saw durability.
Also beware of the "full synthetic" trap. In the USA, it is legal to call an oil made completely from petro, as "full synthetic." Not done in Europe, however -last I checked.
To me, metal protection and flash point are the key issues. When oil reaches the flash point - it no longer is oil and your engine burns up. Some petro Shell Rotella 30W has a flash point of 428 degrees F, yet some Stihl two-stroke oil has a low flash point of 168 F. Lots of BS floating around. If oil is truly synthetic (tier III) it will have a high flash point.

Today's Featured Article - It Can't Be Done! - A Tractor Story - by Neil Campbell. I'll never forget the time back when I was a boy baling hay on our Farm in Big Rapid, Michigan. The most memorable event that took place was a trip up the steepest incline on the farm pulling an old New-Idea baler with a pony-motor for power and a haywagon. I had just talked my Dad into buying an old John Deere B with 6-speeds ahead and I was real proud of it, except it was a little smaller than the Case tractor that we normally
