I would disagree. I will explain my part why.I'm not sure I'd agree with that. It might be true as the trucks leave the refinery, but any fuel, no matter how good, can degrade if stored too long, or under adverse or contaminated conditions.
I'm not sure if the old adage to not fuel up if the tanker is delivering is correct or not, the theory being the delivery will rile up detritus on the bottom of the tank I guess?
But I assume they have those thingamajigs called "filters"?
In any case I prefer stations that sell a lot of branded fuel to "Joe's Country Store and Gas", even if Joe is cheaper.
Modern engines can burn almost anything without noticeably knock or ping, but that doesn't mean it's best for them in the long term.
(If there actually IS a "Joe's Country Store and Gas" I apologize, the name was fictional and only for illustration)
When one pulls up at a modern gas station in north America, how does one determine if the fuel is degraded..? There is no way to tell. Even when pulling up at Joes Country Store and Gas. The gas is bought wholesale and the margin made is miniscule if any. The money is made from the convenience store. But for that to happen people need to be filling up. So the fuel must have a decent turnaround. Independents are really hard to run long term. Thats why most people go franchise now. The model is easier.
Not only that the gas station has to be strategically located now. For example on a long trip people fill up on the edge of the city as they leave(human nature) and again at the 1.5 or 3 hour mark. This is determined by coffee and pee break. The absolute is the three hour mark for gas. Around those areas places like McDonalds, restaurants, coffee houses spring up. Many old gas stations in between those areas don't exist anymore. Or they have gone bust in the last 30 years as driving habits and car reliability have improved. Anything outside of that (depending on what places are in between) people are not going to stop to fill up.
So a gas station needs a specific volume of traffic to be economically viable. Also modern cars don't break down as much, they have better fuel filters, more refined engine and ECU's that compensate if things are going pear shaped.
So statistically speaking speaking, the likelihood of filling up stale petroleum at Joes gas station(or of them existing) is extremely low. Even if one did. It would not impact the engine as much.
