I have a 2011 Yamaha Gas Cart I bought new at The Villages LSL store. At that time they didn't have any pumps, they told me to add the product below when I fill-up. It's in stock at Walmart for about $9.00. When the Marathon station opened I believe it was 2015 I stopped using Sta-bil and started buying ethanol free gas. The very first time out, I played 18 holes at Belle Glade and as soon as I pulled out of the parking lot the cart died. It wouldn't go unless I drove no faster than 4 mph. I called Willie's Cart Service, who I had been using for my cart, and he came out and flushed the carburator and fuel lines. He said the good gas has loosen up all the built up ethanol crud and it broke free and blocked all the lines. I've been using the ethanol free gas ever since with no problems.
