You should see about 3% better gas mileage with ethanol free gas, but it cost about $1 more per gallon. If your cart will sit for an extended period of time then ethanol free would be an advantage. Otherwise it really doesn't matter.

Is your cart EFI or carburetor? I think he means cleaner by not having alcohol blended in the gas which has small amount of water in it. IMO would still add gas additive if the cart set for more than 4 months.

It was quieter because of better insulation added, not FI. FI is only a different way to get gas to the cylinder.

You might want to consider....
 

where your electricity comes from that you charge your electric cart. You might also want to consider where the dead batteries go, where they are mfr'd, how the products a battery consists of are made and what type of power they use to make them. Surely you don't actually believe everything that brings about your "clean" cart comes from renewable, non-polluting resources...no one is that naive in this super computer age where they have the ability to check all of that and more...should they so decide to get the facts before saying: "just saying"...

I'm sorry....I didn't mean to explode your "I'm saving the planet" mentality with facts. :D

It was noticeably quieter once we began using Ethanol free versus regular gas which we used for the first three fill ups or so. We were even considering taking it in for a pinging/knocking noise which was hard to pinpoint. Nothing to do with insulation.

My 2015 Yamaha averages high 40's with regular gas, low 50's with the recreational 90 ethanol free gas. Anyway, it gets a heck of a lot better mileage than any other runaround vehicle I've ever had.

If there is pinging/knocking with regular gas there is something mechanically wrong with your golf cart. These are low compression engines and 87 octane is plenty of octane. I did try one tankful of ethanol free when we first got our cart and it made no noticeable difference. If you are noticing a difference with ethanol free gas you may want to consider having your cart checked out.

I've check my 2014 Yamaha EFI 4 or 5 times and get 46 to 50 mpg.

Thanks. Pinging was the wrong word to use as it conjures up cars which used to do that from time to time. The noise was hard to describe but after 18 months it's running like a champ and I've used Ethanol free ever since.

You must of got a real special cart . Everyone I know gets anywhere between 45 and 55 mpg.

Consider Occam's Razor. Which is more likely: he is getting much, much better gas mileage than everyone else ( 50% better ), or his odometer calibration is off, or his odometer is set to report kilometers instead of miles?

Wow! Have an ax to grind here? The poster was just making a comment about an electric alternative. I don't think the post mentioned anything about "clean" non-polluting, etc.

I have both gas and electric carts. They both have their advantages and disadvantages. However, this is not the topic of this post... MPG is.

It does make a difference. Plus, no ethanol makes it better for your engine.

Who drives 60 miles a day in a cart? This place is only about 13 miles or so top to bottom and at an average of 16 MPH that's almost 4 hours in a cart. Any new electric can handle that easily but why would you?

My 2013 Yamaha EMI has over 27000 miles on it and I've never put anything but regular gas in it. I've never put any additives or used any special gas and it still runs as if it were new.

Who drives 60 miles in a day.? I have many times. Whatever I'm doing in The Villages I take my golf cart. Doesn't matter what the weather ,how much time it takes, or the fact that my car has AC & heat and it gets me there faster I still take my cart. Everyone talks about the main reason they moved here is the lifestyle. Well to me a big part of that lifestyle is traveling around in my golf cart. I live south of 466a and would never think of driving my car to play Lopez or Orange Blossom and have to use one of their carts when I can drive my own. JMHO
