I understand
There's a section of major road here with three stations: Mobil, Shell and Speedway. The same guy owns all three, and the gas tanker goes from one to the other to the next. The reason for the three nozzles is the grade of fuel - 87 vs 89 vs 91, not the brand.
I'm very well aware how the trucks work. That's what I was trying to convey. Each truck has dividers carrying different grades of octane. I must have NOT made myself clear??? Ethanol or conventional gas.
In my area there only 2 distribution centers. They both receive fuel off barges on the Cumberland River. I'm well aware, since there only two distribution facilities, that even Kmart will get the same gas a Exxon. Shell does receive its own barges. Shipped to the same two distribution centers. Non Ethanol is also shipped on its own barges. My Brother In Law has worked for one of the distribution centers for the past 25-30 years.
But Non Ethanol tankers only do Non Ethanol stores, Carrying Each grade. Shell only does their stores carrying each grade. But after the Big flood here in Nashville in 2010. It was very hard to get any fuel. The barges couldn't deliver. And allot of the underground tanks at stores and gas stations got flooded. When the rush for fuel lightened up. Our Kroger was one of the few that even had gas being delivered. People would see a tanker going down the road and follow it, hoping it was going to near by store. And if it did, they were texting and putting it on social media! Long lines would form. It was crazy here for about 3 weeks. And I was pumping gas at Kroger and the tanker rolled in, with 5-6 cars following it and I heard a guy working there, yell "what kinda gas you got for us today" the driver said "Exxon".
And I'm VERY shocked no one hasn't mentioned Summer Blend or Winter Blend Gas? I just started hearing about that junk 20 years ago? What kind'a harmful chemicals does it contain??
But I still feel, non ethanol fuel for small engines is the only way to go. I'm not sure If it's the cheap alloy aluminum castings that they now use for carburetors? But I do know It ruins seals and floats, needle valves. Because of the varnish build up of regular fuel. Or maybe it's the chemicals in summer blend or the winter blend gas? But It does harm "most" small engines that get stored or NOT used for any length of time. And even takes a long term toll on small engines even if used frequently.
But if you've never had a carburetors issue in recent years with your small engines. You must be living right! Because I've had to throw away too many weedeaters that still looked BRAND new over the years because of using conventional gas. That would cost more to repair, than a new one costs. If you could even get parts for the Chinese "Craftsman" made junk!
