Canned Gasoline?

[Garandman]

We buy MOGAS (no Ethanol) at a local airport. Many of them have self-serve pumps. We pay $4.95 per gallon at Hampton, NH airfield. I use it whenever possible in our small, carbureted motors.

When I worked in a petroleum analysis lab in the 1960's, reciprocating engine aircraft used only AVGAS. All other gasoline motorized equipment and vehicles used MOGAS.

What I have been told, and have proven by trying, is that the proper ratio is not what the equipment calls for, but what the oil is rated for. I have successfully run modern synthetic 50:1 mix in my older equipment that was rated for 16:1 when they wrote the manual (because that is what oils of the day were mixed at). The 50:1 stuff is simply better at lubrication and doesn't need such a high concentration in the fuel.

Exactly!

Additive technology has improved over the years, to the current JASO-FD standard. A FULL
synthetic oil, designed for 2-strokes, with do even better, WRT wear.

Decades ago, a Stihl owner's manual said to mix at 16:1 using motor oil, and 40:1 if you buy
the synthetic pre-mix 40:1 fuel from Stihl. Stihl may have been the first to sell these synthetic
pre-mix fuels. Currently, they sell a 50:1 synthetic fuel, and enhance the warranty if you use
it.

If you use excessive oil in your fuel, you will increase soot build-up in the exhaust port, which
eventually scratches the piston and rings. I have torn down many saws, and I have seen
extreme amounts of soot in the exhaust ports, esp on old and pro saws.

It seems that 2-stroke motocross folks have been using full-synth oils for well over 40y, and they
get around the high ratios by cleaning the exhaust ports every few dozen hours.

They have pumps for AVGAS and MOGAS. MOGAS is ethanol and lead free.

i dont want to use 100LOW LEAD fuel in something like a chainsaw or weedeater where i am stationary in the cloud of exhaust for periods of time

Torco 100UL is UNLEADED that's what "UL" in the name stands for.

I go through about 90 gallons of gas per year. At $10/gallon, that would be $900 VS, say $250 on regular gas(even less this year). I'll never have $650 worth of fuel related problems in a year. Ever, never, ever. It would be fiscally irresponsible of me to spend that kind of money on something with so little return. I just can't understand why anyone would do that? Its crazy.

It's not the cost of repair, it's the cost of the down time while the piece of equipment is being repaired. It would be fiscally irresponsible to not understand the difference between the cost of repair versus the cost of time being wasted through non-productivity.

Do whatever you want to do - but, don't wrap the mantle of fiscal responsibility around your shoulders and pretend you're making a rational choice when you're not looking at the entire cost of a piece of equipment down from bad fuel.

I've needed carburetors rebuilt, and had a number of other problems directly related to gas with ethanol. The last time, it took four weeks to get the mower into the repair queue, and then 3 days to get it fixed - mighty inconvenient - and definitely NOT "fiscally responsible."

I decided not to have those kind of problems since they were within my control.

If I used 90 gallons a year, I'd buy it in 55 gallon drums. The cost goes down significantly when you buy in larger quantities.

For the amount I buy per year, the cost is of no concern as I know everything starts every time no matter how long the gas sits in the equipment.

As for draining the equipment - I've tried that including running the equipment out of fuel. No matter what you do, there's always some residual fuel in the carburetor. It can gum up. When that happens - you're rebuilding the carburetor.

The last piece of equipment I had to have rebuilt was exactly that scenario. Run out of fuel, stored over the winter. Next spring - won't work.

No thanks. I hate wasting my time with repairs. I'll spend the extra money for better fuel and eliminate that problem.

Why not? 100LL smells great!

Seeing how I've had one $1.00 repair bill due to E10 in 30 years, I'm going to be thankful that I saved $19,500.00 in fuel bills. It put my kid through college.

You got away cheap Mossy......

You could get all crazy and buy MOGAS for $5 a gallon at the end of the season and run that through all your equipment as part of fall (or spring) maintenance.

The only equipment that gets E-free all the time is the chainsaw and Stihl brush trimmer. Dirt bike, lawnmowers and snow throwers just get it for the last couple tanks, because It's a bit out of the way to buy the MOGAS.
