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.
