Canned premix is alkylate, very stable compared to even non ethanol pump gas.
I've used TruFuel for years with no issues. Chose TruFuel because it's available in 40:1 ratio, uses JADO FD oil, and costs the least.
Actually, I use them both, Tru-Fuel and Echo Red Armor. I don't run my saws a lot and they sit a lot so for me, Syn Fuel is a viable alternative to pump gas, e-gas or not and 'Rec Fuel' regular with no corn alcohol is hard to get here. Nearest station is 20 miles from here and it's expensive too. I don't factor in the cost of syn fuel at all, don't care actually. If it was 50 bucks a can, I'd still buy it and I've had no adverse reactions with Tru-Fuel at all but again, I use both, whatever is available in my travels, I purchase. Presently, there is a full can of Red Armor on the shelf and 3/4 of the gas can I use to fill my saws has TF in it and always 50:1 unless it's a new saw, then 40:1 for the first few tank full's. I'd rather have no issues than an issue when I require them to run. Not a brain fart for me at all, just common sense.
Far as all my gas powered equipment is concerned, Zero Turn mowers, roto tiller, portable genny and the rest, I always use Blue Marine Stabil at the recommended dosage (not cheap like the red, stinky stuff that IMO, does nothing but stink) in everything and the gas tanks are always full over the winter months (now) and they always fire right up after sitting for an extended time in the unheated barn and I disconnect the starting batteries (positive terminal only) when storing them (and I make sure the batteries are fully charged as well),
Never had an issue in the spring so far at least.
My diesel equipment (tractors and pickup truck), which also sleeps all winter in the garage) all get Archoil fuel additive as well as AR 6100 Nano-Borate oil additive in the crankcases and the fuel additive in the fuel tanks and everything farm related (as well as the cars) get a steady diet of 5-40 Rotella T6. I have a big investment in ag tractors and sometimes in the winter I need them to start when it's real cold out (like now it's 18 ambient and 18 in the unheated equipment barn and no electricity in there to plug them in (block heaters) so it's always a stone cold start and the starting batteries on the tractors also get their positive terminals isolated, via a disconnect switch and no matter how cold it is, when I reconnect the positive terminal and give them 10 seconds of pre-heat, they fire right up, no issue.
I use 5-40 T6 simply because it allows the big diesels and car engines to crank easier when it's real cold out and unlike most people, my starting batteries get renewed every 4 years and everything gets 'Alliance' flooded cell batteries I purchase from the local Freightliner dealer because they turn over starting batteries in frequency so I know their storage batteries are fresh and viable. Any storage battery sitting on a shelf idle, is wasting it's life away (sulfation) and I cannot afford to purchase a battery that is half dead anyway.
So yes, I use canned fuel in the saws, always and will continue to. I've had zero issues with either brand despite what I've read on here. It's expensive but I don't really care much. it works and the saws fire right up no matter how long they sit. One thing I always do, is, I keep the full cans of syn fuel tightly capped when on the shelf awaiting to be used and the fuel, as well as my saws and everything else are in my heated and air conditioned shop, not in some unheated space. I keep the shop at a constant 60 degrees in the winter and 70 in the summer. I have to with precision machine tools to maintain their machining tolerances.
Not going to deviate despite what I read on this forum concerning syn-fuel as I've not experienced any of the posted ill's myself.
Finally. from my observance (only), the Red Armor don't produce exhaust carbon at all. USDA spark screens stay clean and no carbon buildup in the exhaust ports either. Not sure about the Tru-Fuel because I use mostly Red Armor 50-1. Back when I used Stihl pre mix bottles in Rec Gas and it produced exhaust carbon in the exhaust ports and well as clogging the USDA spark screens. Not observed with Red Armor.
I'll purchase whatever is available at a store in my travels, not at all biased one way or another so long as the infrequently used saws start up and I have no intake issues from gunked up carbs, hardened diaphragms or mummyfied fuel lines.
