I could add a little to this discussion. Premium gas has a higher OCTANE rating than regular gas. and therefore costs more. Some high performance engines have a high piston compression ratio and they NEED premium gas to prevent the "pinging" which would occur if regular gas were used. "Pinging" is hard on the pistons and for too long of a time could require a VERY costly ENGINE OVER-HALL. Most non-performance modern car engines use REGULAR gas. Using premium gas in an average engine with a relatively low compression ratio won't harm the engine, but it is just a WASTE of money. The REVERSE is NOT true. Do NOT USE regular gas in a high performance car designed for PREMIUM gas.
..........golf cars use regular OCTANE gas.
...........ethanol-free gas MIGHT (??) be better for someone that drives their cart and then lets it sit for 3 or 4 weeks at a time. The ethanol while sitting can, in some cases, form a glue-like substance with condensation and then that MIGHT clog up a fuel injector.

You can run "pump gas" (i.e. E10) in any 4 stroke (non diesel) motor.
When E10 first came out, there were some "urban legends" that the rubber components would deteriorate quickly. If you have any concerns during storage, just add some stabilzer.

stabilizer.

What us "recreational gas"?

100% spot on! Unfortunately some won't get it.

Well, I do agree with your "opening" sentence. There might even be some (a minute few) addition btus in the fuel. But with this logic, why not run premium? Wont hurt (except in the wallet).
Bottom line E10 is everywhere and all current gas engines are designed to use it.

Where did you get this information.
Octane has nothing to do with the amount of ethanol in the fuel!!!!
87 octane and 93 octane could (would) be 10% ethanol at most gas stations.

Golf Cart Guy recommended any gas of 89 octane or higher.

Golf Cart Guy recommended to me I use gas of 89 octane or higher.

Ethanol vs Non-Ethanol Gas
 

Here is what you need to remember: Ethanol Gas - Bad, Non-Ethanol Gas - Good. However, there is always more. If you buy non-ethanol gas at any regular gas station where it is not dispensed from a stand alone pump, but from one of those pumps where you select you fuel type, because there is always gasoline remaining in the pipes to the pump and the pump hose, the first half gallon or so pumped into your cart will be whatever grade of fuel the last person bought at that pump, which will almost surely be Ethanol gas. The benefit of getting your gas at the Villages Golf Cart store is that you will get 100% non-Ethanol fuel. The downside of buying at the Villages Golf Cart store is that the cost per gallon is substantially higher.

Learned my lessons the hard way. Yes I have had to replace the carburetors on a small generator and Weed Wacker. The problem, regular gas. I now use non Ethanol Gas in the small engines. Since I paid much more for my Golf Cart I think I will use non ethanol Gas.

I use stabilizer when we leave for the summer. 2 2016 gas carts, no problems

I've used regular gas station gas on my Yamaha 2018 Quiet Tech with no problems. When I used to go north for three months at a time I did fill up with the Non ethonol gas. What kind of gas do you think all the landscapers use in this area? I'll bet their NOT using gas that costs almost a gallon more. And their engines get a lot more use than you will ever give your golf cart.

I keep a bottle of Sta-Bil and put the appropriate amount (it comes in a handy bottle for that purpose) in my power equipment tanks if the gas is not going to be used immediately.

If, like them, I used my gas powered equipment daily, I’d use “regular” gas as well. I don’t, so I choose to use ethanol-free, especially in a generator that sits for months and months without being used.
