Ethanol Free Gas
 

Can one safely use ethanol free gas in a car?

OP, it's usually the other way around but the answer would be it depends on the octane of the gas and the octane required for your car. Your car manual will give you that answer.

Yes.

Firstly, I am not a corn farmer nor do I benefit in any way from government subsidies to the corn industry, so I will tell the truth and say that you can absolutely use ethanol free fuel in a gas powered anything. Your carbon footprint will be imperceptibly larger.

I had a problem in my Yamaha golf cart the first time I used ethanol free gas. About a year and half ago right after the Marathon station opened I switched in my 2011 cart. So it had been on regular gas for about 4 years. Put the ethanol free in and went to play 18 holes at Belle Glade. Got to the course, played 18 holes everything went fine, then pulled out on Moyer to leave and the cart died. I had to hold the choke out all the way while driving and the cart wouldn't go over 5 mph. If I sped up or let go of the choke, it would die. I live off St. Charles, so it took over an hour to get home. Next day I called Willie Wilcoxsin, who does my regular servicing. He said that clean gas probably knocked off all that ethanol build up on the carburetor and fuel lines. He flushed everything out and the cart has run great ever since.

Double check the octane rating of the ethanol free gas, if it is the same or higher then what your car requires, you are good to go, if it is lower, you may have 'pinging' problems until the computer changes your cars timing.

Not sure why you are asking
 

Marathon is pushing ethanol free gas. It is possible, but a stretch that you will get better gas mileage the reason is there is more BTUs in gasoline then in ethanol (alcohol). The gasoline you put in your car is MAXIMUM 10% ethanol-look on the pump next time you fill your car. The fuel at Marathon says clearly for small engine use. That is the LAW. If, there would be any better fuel mileage it will not be equal to the extra that they charge per gallon.

Your golf cart was designed to run on the 10% fuel.

If, you have a few gallons of the ethanol free gas and are wondering if it would hurt your car if you wanted to get rid of it-it is fine.

Maybe that is the newer EFI Yamaha cart, but when I purchased my 2011 cart new they instructed me as long as I use ethanol gas to add to the fuel Stabil Outboard Motor Additive available at Walmart for about $10. So I switched to the non-ethanol gas in 2015 so I could eliminate that, and to help the cart run cleaner and smoother and last longer. For almost two years it has been running smoother.

IMO Gas is gas. Anything you buy at the pump your car will burn which includes AVGas. corn gas get the least gas mileage in anything. It has to burn more to produce the same amount of work due to less energy when it exploded in the combustion chamber. Why don't small aircraft piston engines use corn gas? They don't want that junk in engine the keeps in the air.

Back to the OP --- do you use ethanol-free gas in your automobile and why?

You absolutely can and your car will thank you! The real issue is why does the government force us to use gas with ethanol? Let's see, people all over the world are starving, so let's burn corn to run our cars, Hmmm?

Ethanol Free Gas
 

Carbureted vehicles can have ethanol gas issues, electronic fuel injected won't. Carburetor jets need to be up sized to compensate for the decrease in energy value. Typically, intermittent stumbling will occur in older carbureted vehicles. Ethanol also has a nasty habit of absorbing moisture ( H2O) further complicating drivability issues. Rubber hoses used to deliver the fuel were an issue with older vehicles but the newer rubber compounds can now handle the ethanol. I know automobile engines, I don't know golf cart engines so what I've stated applies to the latter.

E-90 is ok but e-85 has to have special seals. I have been using e90 gas with e85 booster. I buy at walmart for $8 dollars. Enough for80 gallons. 1 ounce per 5 gal. of gas. I get more power and economy. It is supposed to dispel the water. Been using it for years in my new iand older card.

I believe it is the other way around the cart is designed to run on ethanol free gas, the reason ethanol free gas is sold at the cart gas stations.
