Must be my day for respectfully disagreeing

I worked building/piping gas stations for about 5 years after I got out of the Army. I also set and removed gas pumps and took them in to be re-conditioned and re-sold.
We serviced Mobil/ Texaco/Shell/ among others and also many independent dealers who bought their gas from the big boys wherever they could get their best price.
I can tell you as a fact, that depending on the additives, the internal plumbing of the gas pumps, and in turn your carb/fuel injectors can be significantly affected with buildup that will effect fuel economy/ fuel filter life and overall performance.
I don't know what the " cleanest" fuel is nowadays, but then, Texaco had the best gas period. You open up the vital of a gas pump, and it was a clean as could be, others would have varnish/sludge deposits that we would use a carb/injector type cleaner to clean when we re-conditioned them.
Another thing is that on a 20 thousand gallon underground fuel tank, especially metal, you would easily get 500 gallons of water from condensation from tank and gas lines running to gas islands. We regularly serviced gas stations and pumped the water out keeping it below the suction line that is about 6" or so off the bottom of tank for this reason. If you ever read about or had water in your gas from service station, it's becasue they didn't check and keep the water below that line. Tandem gas delivery trucks especially in cold climates will have significant water in them due to condensation which ends up in the underground storage tanks.
I if you've ever seen guys with the long wooden " ruler" checking the fuel level in the tanks, you might not be aware they put a gel on the end of stick that turns purple ( at least back then), which tell the operator that the water is getting high enouhg it needs to be pumped out.
You also get particulates in the gas from various sources. On your car, the in-line fuel filter deals with it. Ever cut into a old fuel filter? You'd be amazed what you might find. Cleaner the filter, better the quality of gas your using.
Depending on your stove, fuel quality may or may not be a problem. I guess experience will tell you if your stove runs well on the cheap stuff, but why find out the hard way, when a little TLC will eliminate all doubts

I'm guessing on the newer " hi-tech" stoves that wring the most BTU'S out of the smallest amount of fuel, the purity of your fuel choice can make or break your cooking experience.
Adding some carb cleaner as I recommended may not make a difference in your stove of choice, but it won't hurt it either. Stoves are like people who gradually get out of shape. You don't even realize how your performance is affected until you go up against a " fit" model
