Thx, Mike. I went there a handful of times, until my wife's SUV experienced hard starts on an almost empty tank. I suspect that water or gunk was in the gas and when it got low enough the fuel pump got some in the lines. I ran the wife's truck down to almost E and then filled up at Shell and try to start but it would only crank and crank. After a couple minutes of cranking she finally started running. I have been putting fuel line antifreeze/water remover in each tank since then. It's been about a month or so. Hopefully the water/gunk is out of the tank. I am leary of going back to that Sinclair. Have you tried running any of your vehicles down to E or on fumes while using that Sinclair gas?
