I bought a new snow blower and the dealer told me that he put a free fill of synthetic gasoline in it in case there was no snowfall for an extended period. The synthetic gas is not supposed to degrade and therefore not cause starting issues for extended periods. This stuff is expensive at about $30 per gallon. Has any of the forum used this stuff and was it up to the claims? If it is good to go, I may purchase a gallon and use it to do a final run out every year at the end of mowing season to preclude starting issues come Spring.

As best I can tell, the premixed 2-cycle non-ethanol fuel in a can is synthetic.

I don't know anything about synthetic gas.

I do know that alkylate gas is good stuff -- I use it in my chainsaws. Alkylate gas is supposed to be good for a year after the can has been opened -- either in the can or in the machine. Alkylate gas occurs as a natural part of refining crude oil.

It is probably VP or similar. It is high octane and non ethanol. Good stuff.

Hopefully they did not put that in a 4 cycle motor. That’s a pretty good way to foul up the spark plug on a brand new machine.

Ethanol free with Startron fuel additive is what you want to be using.

Even if it does not snow just run it a few times throughout the year.

Could be anything, but 'synthetic' it is not!

We can thank the Allied Powers for defeating the Axis Powers and obtaining the "how to" from the Germans.

Nazi Germany was creating over 90% of their wartime use of Fuel and POL (Petroleum, Oil, Lubricant's) from synthetic production.

Remember this when you trap a person into a corner and force them to rely on wits and nothing but what is available, for he may figure a better way of using the sticks and stones, forgetting name calling and what not...

Yep, generally via coal hydrogenation and coal liquefaction, since Germany has large coal deposits.

It’s good shit. Porsche has been hard at work developing it. My sport, MotoGP, is converting to it in I think 2027, making it part of the rules. It does last longer, doesn’t degrade, etc. The only issue with it is the cost. The cheap route is just fill with Stabil towards the end of the season.

Gasoline has over 400 different hydrocarbon compounds within. ASTM D6733 test identifies the compounds and the relative amount. Degradation and oxidation can occur with some compounds. A purposely synthesized fuel can be less likely to degrade or oxidize.

A fuel can also be formulated (not synthesized) by combining various refinery streams that are primarily one form of a compound. In this formulation, more stable hydrocarbon compounds can be maximized.

You can achieve the same effect at much lower cost by simply using ethanol-free fuel from a gas station.

Natural gas can be cracked onto acetylene, then to ethylene which is processed into "gasoline". A high octane gasoline.
