The higher octane in the gas makes less stain on the engine. Also remember it not a car engine. It’s a four cycle engine. U can get the tv gas at 7/11 in colony or gas station at pinellas

The electric was out all day at Sumter Landing. No electric, no pumps!

We have a 2011 Yamaha EFI, ten years old, the book says regular up to 10% ethanol. We've always used REGULAR GAS and it has been fine.

Like most of the posts, they are OPINION. CLAIMS such a better gas mileage. It is very unlikely that anyone can accurately measure gas mileage. Better wear, it s unlikely that anyone can properly measure comparative life.

Our golf cart is 11 years old. A Yamaha EFI always run on regular gas and it is fine.

Yamaha didn't release the EFI motor until the 2012.5 models as an option.
Starting in 2014 all were EFI, no option to get a carburated motor.

What do you think a car engine is a 4 cycle engine just like your golf cart with more cylinders

My brother is a Kawasaki/Polaris dealer here in SW Indiana. He owns numerous bikes and 2 side by sides. Runs regular gas like me and his bikes sit for months over the winter as well. Neither of us has had any fuel issues. Now as another poster said, if it's an older carb it could be an issue.

They also advise regular gas to their customers on all the brands he sells.

At the most, some fuel stabilzer for the winter can be an option, but I don't even do that.

Besides, if ethanol was a problem the oem's would recommend non ethanol for their products, but they don't.

Me too. I have always used regular gas in three Yamahas, no problem.

Actually the problems with older boats having issues with the E10 gas was not so much with the fuel lines but with boats that had fiberglass fuel tanks. The E10 would leach resins out of the fiberglass and create a gummy-like blobs that would get sucked up in the fuel lines and create havoc on the fuel system. I never had any issues as I had aluminum tanks but I knew two guys who had to have their fiberglass tanks replaced with aluminum and that was expensive!

I put the same gas that goes in the car. In a pinch I have gone the Village Cart shop as in Spanish Springs it is the only gas around.

On the few occasions I use 7-11 gas at colony, the cart will back fire coming to a stop. No idea why, but it’s annoying. Now 7-11 is no longer on my list.

I have been using regular in my 2016 Yamaha for 6 years now. No problems yet.

Ethanol Gas
 

7 Eleven in Colony.

Golf carts are sold all over the country /world. They are designed to use gas with ethanol.

I have a carbureted Yamaha that I run with regular gas when I am in TV. The last tank before I leave for 3-4 months I fill up with ethanol free gas and my neighbor drives my cart around the neighborhood at least once a month. My engine consistently runs smoothly and quietly.
