Since I rarely fire up my 2-stroke cycle equipment except when I absolutely have to- I've got several brands of oil to choose from if I need it: Stihl, Tanaka (never used it but came with my trusty TBC355 brush cutter) and AMSOIL Saber which I purchased from Pablo when he lived in Lynden.
I don't have any real preference but I have been quite pleased with AMSOIL products in other applications.
Now if there were an easy way to remove gum and varnish from neglected fuel systems in two-cyclers...! This is OT but FWIW I used about 30% toluene and some FP60 in my Echo trimmer which was very "boggy" on the throttle- it definitely helped (but then again, toluene is about 114 (R+M/2) octane!!!)
ow if there were an easy way to remove gum and varnish from neglected fuel systems in two-cyclers.
An ounce or two of prevention--use AMSOIL Stabilizer, or at least PI, or Stabil in the fuel before you put it on the shelf, or in the garage, or in the shed, or wherever else
Using amsoil sabre@64:1 in a 40:1 spec'd Bolens string trimmer.
this trimmer would barely run at 40:1,so with the amsoil she gets more fuel now and starts easier and has far more power than the walmart oil at 40:1
Right now Walmart TCW3 Outboard oil, 32:1
Weed Whacker (only 2 stroke piece of equip) is running like [censored] and the exhaust smells nasty. Gotta use up this gallon which is gonna take a while.
Next gallon will be Echo Semi Syn at the ratio listed on the bottle.
Using QS 40:1 bottles that I got for $.49 @ Menards or a comparable sized bottle from TSC for those items that are 40:1.
For everything else, using Speedway 2 cycle oil out of a quart bottle. Bought a bunch up for $.25 per quart at a Speedway location that was turning into a Pilot. No problems with any of the three.
Amsoil Saber at 85:1 and I use it commercially every day of the week. When we used Echo oil at 50:1 every couple of months the exhaust ports, mufflers and spark arrestor screens would clog up and prevent the machines from making any power. Same applies to other standard 2 cycle we have used such as penz, super tech, stihl. Once we switched to the amsoil saber it has actually cleaned up the ports and keeps the spark plugs clean. It creates no smoke and has a pleasant smell.
I don't mean to criticised Saber and I think it's probably a good oil. But if you have a weed eater or whatever and it says mix synthetic 2-stoke oil 40:1 or maybe even richer, I figure it is jetted for that oil to fuel ratio and I don't want to run an oil 80:1.
Maybe Saber has highly concentrated additives and good lubrication properties but it still seems like the engine would run richer at least. That might not necessary be a bad thing though. Different strokes for different folks I guess.

I didn't change any carb settings and everything runs great with it at 80:1 in equipment spec'd. at 40:1.
I recently did an exhaust port inspection on the saw, and all good there. No carbon buildup, which I hear is typical for Saber Pro. There was an extremely thin coating of varnish on the piston crown, but that was it.
