I have a 2015 Yamaha cart which has about 3000 miles on it. I have been using 10% ethanol gas since I bought it second hand in 2016. I have seen the comments about Sta-Bil. That product appears to be a fuel stabilizer for long term storage. My question involves the use of Seafoam Gas Treatment which is used to clean gunk build up on the internals of small engine. Does anyone know if Seafoam can be used "safely" in a gas cart engine?

Most gas sold is a blend to include a small amount of ethanol. The blend is either 5% or 10% ethanol mixed in. That is the norm for most gas sold.
The NON ethanol gas, obviously doesnt contain ethanol and will produce slightly more energy when ignited (burned). Not enough for you to notice.

E85 gas is a blend of 85% gasoline and 15% ethanol. This type gas should not be used in cars that are not E85 capable nor golf carts or small engines.
Stainless steel tubing and other ss components are required for E85 gas due to its corrosive nature.

In summary, you are ok with the 5% or 10% blends normally sold when using in your golf cart and basically wasting a little cash if purchasing ethanol free gas.

Actually the reverse is true. E85 is 85% ethanol

I use regular gas in mine and Helene's golf cart. (Actually I don't put it in, my dear husband does) Anyhow this cart is a 2001 Yamaha. Gets us where we're going. Henry uses regular gas in his new Club Car.

What is the issue with your golf cart that you are trying to solve with Seafoam? If you don't have any issues then no remedy is required.

Yamaha salesman told me that as long as the gas is used up within a month, regular gas is fine. Yamaha's manual states regular gas. Have 2019 also.

Read your Manual . Regular(lowest price) 87Oct gas is perfectly ok for your GC. Any make. Sta Bil and gas additives are a marketing ploy and have very little real benefit (except for those in it's sale chain) Go on line and read the research. Paying a 30 per cent premium for no ethanol gas is bizarre . I have owned 4 Golf Carts over 10 years here. Always used regular gas. Never had even a minor engine problem
I average 300/350 miles a month over that time. think PT Barnum.

I’ve talked to a lot of small engine repair people about this and was told the following: Always use it in things that are used less frequently, gas lawn mowers, trimmers etc, most said that even though golf carts are used a lot it takes along time to use up the gas so if you can foot the bill get the ethanol free gas.

Just my experience: 4 carts over 10 years. Left many times unattended for 2/4 months at a time. No additives, regular 87 octane, No-none- engine problems . Instant start on return to use.

Using reg. gas is OK, if not sitting for any length of time! However, I always use a stabilizer in reg. fuel for small engines .

I'm feeling a little gassy.

I have worked on small engines, cars etc. and have seen the benefits of using a fuel stabilizer. You may get away with out using it, but why gamble for the price of a bottle.

Buy it, it’s recommened for our carts

Well, I don’t know if Ethanol is better or not but I bought a brand new 2013 Yamaha in Sept. of 2012 & in Dec. of 2017 I traded it in for a 2018 Yamaha & I had 26,000 miles on it & it still ran like new, no issues as far as gas. Just get it serviced regularly.

yes, I hate paying exorbitant price just for convenience
