Yamaha urges against the use of a stabilizer unless you are away for long periods.

I also noticed the difference once i filled up with non-ethanol gas. The engine was noticeably quieter and smoother. I fill up at Marathon.

Second that; Owners manual is the best guide for gas :clap2:especially if in warranty

Unfortunately qualitative results are more in vogue on this subject then quantitative. Do what the owners manual states and the engine will perform as designed, case closed.

How much is the ethanol free gas at Marathon? Last time I was at Lake Sumter station it was 2.99 while regular unleaded gas at Shell was closer to $2. That's a pretty significant price difference.

The golf cart mechanics I have spoken to all recommend using non-ethanol. You can get that at Gordon's Garage in Lake Sumter, near Barnes & Nobles, or the Marathon gas station in Pinellas Plaza. If you can't get to one of these stations, occasionally filling up with regular gas won't hurt the cart.

Personally, I consider the mechanics the experts. Rather listen to them than even the owner's manual. They know what goes wrong in carts and why.

And the people that DESIGN, BUILD, and WARRANTY the carts don't?? :ohdear:

Good response! :bigbow:

Premium at Colony in $2.75 range as is Marathon at Pinnellas Plaza.

If these guys were experts on the internal combustion engine why are they working on golf cart engines ? Seems to me that expert mechanics would be working on equipment more sophisticated than put put engines. Do what the owners manual says ( it was written by real experts ) and save a buck a gallon in the process.

What is the best gas to use in Yamaha gas carts?
 

93 or higher octane gasoline does nothing that 89 octane can't do in an engine designed to run on 89. That is a fact. Doesn't matter if it's a cart engine or a V8. Higher octane allows the fuel to combust slower, nothing more. If an engine is built and tuned to spec for low octane fuel, that's all it needs. Anyone telling you different is blowing smoke, not facts. Also, all modern engines have hoses and components designed to withstand ethanol enhanced fuels. Save $$$ and do what the owners manual states.

When posters address the best gas o use for a Yamaha gas cart does it make a FI engine make a difference? Carts and clubs had given me written instruction suggesting less than 10% ethanol 87 octane was fine and that if I wanted to use a stablizer I could but it wasn't necessary and then provided me with three different brands

My neighbor has had his EI gas cart for well over a year and started with a stablizer than dropped it and hasn't noticed a difference. I suspect it because he is not gone for long periods at a time

Since the dealer is coming by my home on Wednesday I intend to revisit this issue

So true

For some reason people want to spend(waste) money . They have been brain washed by Oil companies and supplement producers. Many mechanics, salesmen and next door neighbors have little or no actual knowledge of the chemical and mechanical effects of fuel. I have two carts, Yamaha EZGO,drive them to death over the past 5 years. Always fill with lowest octane I can find, never put anything else including stabilizer in the tank. For many people the placebo effect is working. Have never experience even one engine issue.

I don, think mine is an isolated case.

...

Owner suggests regular from Colony, is this non ethanol?
Why this particular place?
