Just to add to the confusion, I will post my personal results I have had with 2 stroke oils in my saws. Started with the Stihl HP orange bottle, ran it in my 026 at 50:1 for the last 16 years with no issues.... the piston rings and piston skirt were very clean and shiny, cylinder walls still have cross hatching, may have lost 5 lbs of compression over that time - small amount of black loose carbon in the muffler can, no dampness. Switched to Stihl Ultra a couple years ago, works equally well, smells a little perfumey, did not notice any performance change but it actually pulls over easier and starts easier in very cold weather. In the last few months I have switched to Lucas full synthetic. ( Disclaimer, I hate overpriced boutique products that don't actually work any better than much cheaper alternatives, ie: Lucas and Amsoil) . Incidentily, I tried using a few of the Lucas products just because they were on sale or some last chance miracle fix that was supposed to cure various ailments...... surprisingly, they worked very well).
So the results I have had with the Lucas full synthetic at 40:1 have been equally impressive in my opinion. The saw runs snappier than with the Ultra, virtually no smoke, no stink, the inside of the muffler can is slightly tacky( Not wet) and it has removed a lot of the carbon that used to be in the exhaust port and muffler. This stuff seems to burn super clean with no wetness on the exhaust side at all. As someone else mentioned, the oil on the piston is a very thin layer but is extremely slippery feeling, almost like a super slick coating, but not wet. I think this is due to the oil combusting very clean and seemingly adding power. I am not an expert and think that anyone can use whatever they want for oil at whatever ratio they want.... I have no information on any of the other oils. But I really like the Lucas full synthetic at any price point. (32 bux for a gallon).

Isn't the full synthetic Lucas a snowmobile oil?

No!! BS....i tested Pine Sol 40:1 and everything cleaned faster Muphy's is crap
Yes they call it a snowmobile oil, but is formulated to be run as an injector oil or premix. ( I surmise that it is similar to the semi synthetic but that they have used full synthetic oils instead) It has a very low pour point for that use. So far it doesn't seem to realize that it isn't being put into snowmobiles... Lol.
Yeah... but Murphy's can double as a bar oil‼

Its actually recommended to clean EDPM rubber roofs on RV's by the company that makes them also... good ****!!

36/50 = 0.72 gallons per 2.6oz of oil for a 36:1. Or 3.55 ozs of oil per gallon (128/36 = 3.55).

Enjoyable read so far, for the most part. I have used many gallons of Lusas oil at 32:1 and have not noticed any negitives. At $8.00 a quart it is the best easy choice for me to find. Not brand loyal at all and run lots of different brand's products, the biggest complaint being the smell of some of them. If it costs more than $8.00 a quart I would not bother with it unless the Lucas is unavailible. Having said that I am currently running another batch of Stihls white bottled oil. No complaints about it, when the last 6 pack of 5 gallon mix bottles is opened I will shop around and see what is next.
Do folks still see the volume of stuck rings that they used to see?
Why so hung up on easily visible oil film after the engine has stopped running?

It wasn't so much a matter of how. More so of why?

I agree but thought I'd put it out there if someone ever considered it.

Calumet Oil Refinery in Shreveport LA provides the base oil for the Stihl orange bottle according to the Engineer I had a meeting with today. They also provide products for petroleum jelly, WD-40, 3-1 oil, and several Lucas products.

last year around this time i landed a real nice stihl 08s that had sat forever. i didn't care much about it but before i actually dipped into it i decided to try start it. fired right up even after all those years sitting on the old fuel and puffed smoke like you wouldn't believe. the whole area around my house was just blue nasty burnt smokey oil. no mosquito's for miles LOL i swear you could pore oil down the throat of a large V8 and it wouldn't smoke like that. no one should have to endure that while running their saw. i was never around for the days they used motor oil in their mix so had no idea it was that bad.

128oz in a gallon.......divide by.....40(40:1)....equals 3.5 oz per gallon
Divide how many oz. of fuel you have by the ratio you want (32, 40, 50, etc) and that will tell you have may oz per gallon you need
