So here is what is going on.
In any engine with a metal (aluminum or zinc) carburetor, the Ethanol oxidizes and causes corrosion in the jets of the carburetor. You eventually have to replace them if you use ethanol fuel. This is NOT a problem in Fuel Injected engines like the Yamaha quiet tech engines, but if you have an old gas Yamaha or Robin engine that is not running smoothly, get a new carburetor.
Also - all the new engines use Nitrile or other Ethanol resistant Gaskets so that is not a problem either.
Bottom Line - If you have a carbureted Gas golf cart, use non-ethanol fuel (way cheaper at some of the other gas stations other than the TV one, but heck, they are convenient). If you have a Fuel Injected Golf cart - use any gas you want.
I suspect your salesman wants you to buy from TV because they make a lot of money on selling over priced ethanol free gas.
BTW- When I was there we went from Zinc to Aluminum to Plastic Carburetors on the smallest engine line to solve this. Now all small engines have Plastic Carbs that are WAY BETTER than the metal ones. I don't work there anymore, so I have no skin in the game.
Hope that helps explain it.

I would disagree on what he said about bad gas. When is the last time anyone has seen that? Very rare anymore. Todays gas just doesn't go bad. May lose a little octane but it doesn't go bad.
As I said in a previous post, I have plenty of gas powered toys and equipment that sits idle for many months along with the can of gas. Sometimes I don't start my motocross bike or SxS for 5 or 6 months. I've had no issues and I can't remember the last time I had "bad gas".
Bottom line is, gas is a non issue at all anymore.
