The fuel in the sealed / closed can will last 2 yrs. Once in the saw, it will last longer than pump fuel, but anything outside of 90 days is pushing it. As some have posted, run it through equipment when winterizing.
The trufuel that I bought says 5 years in unopened can. 2 years after opening.

I don't doubt you, but I've never seen 5 yrs. But I do know, for sure, most advertising claims are 75% horse poop.
But that's just my opinion.
I own a MS290 that had MotoFuel left in it. It would not start after 7 months without a system flush.
Variables are endless I'm assuming.

I'm not sure what went wrong with the motomix. I have a Stihl pole saw that I don't use very often and that's what I use the trufuel in. I left it for 1 1/2 years with the trufuel in the tank and when I finally went to use it, it fired right up and purred like a kitten.

Andy maybe you got it wrong because my old Mac book says 24:1 using 30 wt non detergent. Just maybe 60 and 70 years ago no knew how to measure. I do know that full synthetic does not mix with others. If you like synthetic you may keep it or not. I do agree mosquitoes do not like 30 wt as well as full synthetic.

The SAE 30 is AMSOIL.......
See how I did that?

I use just about anything modern for air cooled engine. No TCW3
 
Oh dear, I've just ordered some HP Ultra - stepping into the future...

If my saws aren't twice as powerful, last twice as long, use half the fuel which lasts twice as long in the tank I'm not happy.... Or shall I run 100:1 then it's the same price as HP red?

If you use Stihl brand saws, they already do. If you run those silly toys from that country better known for cheese, good luck.
Some guys swear by Ultra. Most swear at the price. If you feel it works better than HP, by all means, use it.
In a saw, I think the orange bottle is more than sufficient.
Stihl came out with Ultra, mainly because of their 4 Mix engines.
HP will carbon up a bac pac in 50 hrs.
HP never does it to a saw.
 
Don't worry, all Stihl!

It's funny, I have very old saws that are perfectly healthy and have run mineral all their life, I have a 461 with the cylinder off atm that's had 50:1 mineral from new afaik. There's plenty of oil everywhere, no need to doubt it, but if all the hype is true I like the idea of synthetic. I have more saws than I need, I don't use them very frequently, I can't buy ethanol free where I am the best I can do is 5% in high octane pump fuel. So I like the idea of the fuel stabilisers to help it last a bit longer once mixed, and it working better with ethanol fuel. And if it does lubricate better that's great, I'll give it a try.

I expect the main benefit is the warm self satisfied feeling you get knowing you're feeding your saw the best, or just the most expensive oil available....

The price is outrageous! 20ltrs of full synthetic oil from Mercedes costs me around £50, 1 ltr of Stihl ultra? £23! Mugged off? Oh yes! And I'm not mixing it 32:1!
 
Not really a debate on which is best but I figured I would throw this info in anyway. I saw a post some time back with the poster asking if the Husqvarna synthetic mixing oil gave anybody else a headache besides him. That set me to thinking, for the last several years now Ive lived with an almost constant headache. Since I use my saws to make a living, theres hardly a 3 day span that passes that I don't use a chainsaw. These headaches were so bad that I was basically living on otc pain meds. In those spans that I might go several days without using a saw, the headaches eased up. So I figured I would switch mixing oils just to see. I couldn't find any husky oil that wasn't full synthetic so I tried stihl full synthetic. No change in the headaches. Out of desperation I picked up a 6 pk of the plain old orange bottle stihl oil, enough to mix 15 gal of fuel. Im on my last bottle now and I haven't had one of those headaches since I switched!! Maybe its all in my head but after 15 gallons of gas burned without a headache, Im sticking with plain old stihl oil from now on. If it burns my saws up by not using synthetic then so be it! I can rebuild my saws a lot better than I can deal with the headaches.
 
Do you deal with the general public? If so, that is the root of your headaches.
Idiots and morons at work could also be a source.
 
Husqy XP oil is a synthetic blend I thought = not 100% synthetic? It doesn't create that same weird smell that HP Ultra does - which gets even weirder as part of "MotoMix." That exhaust is so strange I will go back to keeping a can of the Husqy pre-mix instead, for the random once-a-month cutting when I am not on saw work.

Few things create headaches like trying to run a saw for a government agency.
 
Might not be a 2 stroke but put amsoil in my Harley I never check it with a heat probe . But it seemed to run cooler made riding a lot more comfortable . My old 95 neon had like soap under the oil cap in the valve cover the engine light would be on the car would jump like at low speed or town driving . Put Mobile one in a few years back the engine cleaned up engine light went off no more jumping . I run amsoil in the air cooled engines mobile one in water cooled .
 
I have been researching the **** out of 2 stroke oil lately for REAL info, not opinions. After months of doing this I settled on husky XP semi-Synthetic.

No need to worry anymore.

And my new rebuilt 385XP, ported and MM’ed loves it at 32:1.


If you are a stihl guy, run your stihl oil. Great oil too.

True synthetics that contain Esters can cause real troubles in 2 stroke engines. A little research and you can find this.
