Miles per gallon? It truly does not matter. We put gas in it once a month. The tank if I recall is six gallons and to fill, ONCE A MONTH, takes less than five gallons.

Someone mentioned higher revs and wear. Again, IT IS A GOLF CART. Wear on the engine depends on many things including the load. There is no transmission shift. Going up hill, riding on grass, your weight, carrying two people, four people all put more strain on the engine. Increased load, increased wear. Higher gear with increased load increases wear.

For an economy run, you want over inflated bald tires, you want the wind behind you, you want to get rid of your windshield, roof and sunbrella cover THEN start on the engine and drive train. Heck the body adds ???? 300 lbs.
Manual clutch? Shift-able transmission?

NO THANKS

Oh the yamaha and probably all the others the filler neck is sunk for a reason. Like any liquid gasoline expands as it gets warm. If, you fill right up to the top, trying to do a MOBIL ECONOMY RUN and it gets hot, the gas will expand and it has to go somewhere. It will seep out of the tank.
It might seep into the engine thinning out your oil. Spilled gasoline with a hot engine, electricity-just not a good idea.

When a thread starts out with the word beware, I almost always find out it isn't any really big whoopee-do.

The truth is only idiots over fill the gas tank. Some take the governor out and the engine winds the engine up for for higher illegal speed which eats up MPG. It just glorified lawn mower engine which is not fuel efficient.

So what!!!!!! Not in any hurry to get anywhere. Ours gets 50 mpg as did the 2013 we traded in. Life is good.

Sometimes, quick acceleration is needed and it is very nice to have and my Yamaha electric does have that quick acceleration. Having said that, our electric cart travels only 20 MPH on flat road, up to 21.5 on a downhill run and loses about .2 MPH going up hill. I go way ahead of some carts when starting from a complete stop but they soon catch up with me.

Thanks for the update, just purchased a 2018 and it responds fine when merging into traffic so far.
