All the gas comes from the same refineries and traded on the open market to the jobbers that own the station. The same gas as Costco is also at Shell, etc. The only difference is when the marketer takes delivery, they'll add their "special additives" that make it their formula, like one pint in a whole truck. Like previous poster said, most likely equipment failure somewhere.
Nope. In the 1990s refiners sought to mix ethanol into their gasoline blends. From what I've heard, Shell was rather successful with ethanol blends because their gasoline did not lead to vapor lock (water). Although I'm not sure how much of a contributing factor carburetors were. Anyway, I'd stay away from all Citgos: Citgo Said to Plan $2.5 Billion Debt for Venezuela Dividend They could very well default and send Citgo into some kind of bankruptcy to make payments in Venezuela.
No, I'm correct. When you pump gas at Chevron, Shell, etc... There's no way of knowing where that gasoline was actually refined. Citgo's nearest refineries are in Corpus and Lake Charles, do you actually think that they're shipping in fuel from there to their stations in the Houston Area?
I've been filling up my tank with every brand of gasoline out there, and I've never had any problems.
You think all refineries are the same? You think E85 is the same as Regular 87? I think you have some unfounded beliefs.
No I don't think all refineries are the same. But gasoline refined and mixed with 85% ethanol fuel at Refinery A will be the same as gasoline refined and mixed with 85% ethanol fuel at Refinery B. E85 and 87 are mostly Ethanol anyway. When refineries are cracking a barrel of oil there isn't some top secret process that's going on there. You can take a barrel of crude, start a fire in your back yard and produce gasoline, diesel, kerosene, and asphalt if you wanted to. Sure there are different octanes and amounts of ethanol mixed in, but the product leaving the refineries are the same. This is common knowledge.
