re: Problems with the premix fuel for small 2 stroke engines?

Not possible, it is in a sealed can, residual solids commonly called "varnish" left in a carburetor are the result of evaporation which cant happen without exposure to the atmosphere. Gasoline will also diminish in its available energy by the evaporation of soluble butanes to the atmosphere. Gasoline stored in a sealed container will remain useable almost indefinitely.

When we were kids we used to get 40 W lube oil from a tank battery gas compressor. Would mix it with .28 cents per gallon Billups gasoline to run in my 6 h.p. outboard motor. I still have the motor and it still runs.

It’s funny because most the mfg test with this stuff.
True fuel was the first one to hit the market.
When they test them they actually run hand held products 5 days a week 8 to 10 hours a day in the field. After a few weeks they take random test by bringing in units and tearing them down or sending some to emissions testing. I been to the testing facilities and they exclusively run truefuel for their test.

When I recommended it to customers I rarely if ever see those units come back for fuel related issues. I have seen a few issues people have 4 strokes that someone put 2 stroke premixed fuel in.

99% of the problems I see with hand held product mowers, riders, and zero turns is with ethanol fuel separating even after using a fuel stabilizer or sticking from fuel stabilizer in the fuel. I would rather people use ethanol it has made me rich and I still make a lot of money off my shops fixing these issues.

i have an old echo blower that i've been limping along on gas/oil for several years. it is very cold natured and sometimes just won't run up to full throttle. i switched to trufuel, and it starts every time with little or no choke, and idles immediately. no problems running up to full throttle. it's worth $20 per year not to fight it. chain saw runs much better on it too.

Didn’t even know they sold such stuff. Why would you not mix you own? If someone lacks the ability to do this they probably shouldn’t be operating any type of equipment.

I use TruFuel in all of my small hand tool motors exclusively and never had any problems. But before it came out I mixed my own and never had any problems with that. I have no “season” my gear runs all year long. Take care of your tools and maintain them and it doesn’t matter which one you use, even ethanol if you run all the time. Having said that I do not buy ethanol gas - I have several non ethanol locations close and run all of my 4 wheelers, mixers, equipment on it as they might sit a bit longer.

Everything else, including lawnmowers, tractors etc...is diesel.

Napoleon nailed it again. 93 octane. Higher octane gas.

It doesn't matter on the engine that much being a low compression.one cylinder. I just find that 93 octane seems to sit better.

I've mixed my own 2 stroke gas for 30+ years, and over the last 10 years got tired of killing weed eater after weed eater. Even with non ethanol gas. I started buying the premix stuff, and problem solved. All I'm saying. Apparently others in this thread have seen the same performance difference. Don't know what it is, but the shite burns clean as hell.

Now one thing I would definitely watch out for is using stabilizers in your gas for lawnmowers. I damn near killed mine using that garbage. It had some sort of a chemical reaction and gummed up the fuel system.
