Gasoline is a relatively homogeneous product, but not completely. And up here, there are differences. I do know a number of people in the industry. In fact, I work very closely with former SOPUS and Imperial Oil (our XOM) distributors and a current Imperial Oil distributor, and used to be in close contact with a Petro-Canada distributor. One of the companies I own provides consulting, installation, and repair services to almost every major retail level gas station (and many independents) between Toronto and Vancouver.
Due to a refinery issue up here, Petro-Canada stations in this city were short on fuel for a time. Their preference was to close one station, then move onto rolling closures, before purchasing fuel from another company. They didn't even bother increasing the price and they pretty much successfully avoided purchasing fuel from other sources.
Other oil companies do share refinery capacity and some transport. However, the Top Tier retailers (and other biggies) seem to do much on their own. By that, I mean, a Flying J truck will fill Shells only with respect to Top Tier/big names, and a few independents. And if you think the Shell gas is identical (at least with respect to additive package) that the independents here get from the Flying J truck, you're mistaken. I've driven enough fuel-sensitive vehicles for enough miles to know there is a significant difference. A new station with new tanks is not always enough. It helps, but it's not the only thing. That's not to say a Top Tier station can't have bad tanks, either. However, I've been stung by the majors only twice in all my years of driving, but several times at the small independents, even though I avoid them unless absolutely necessary.
And up here, where there is an actual refinery in this city, I assure you that direct deliveries do occur. More accurately, they're as direct as is possible, with the distribution office and the tanker filling equipment right on the grounds, and I tankers leave there every day I go by.
I wasn't suggesting that the manager was adding additives at the station, and I do not pretend to know how additives get into the gasoline. I assume there is more than one way this occurs. When a Petro-Canada truck is serving only Petro-Canada station after Petro-Canada station and only those branded stations, it's obvious that the retailer need not do that, at least in that case. I also have enough experience to know that even a small delivery truck has enough compartments for at least three varieties of gasoline and two varieties of diesel, depending upon local taxation regimes. That's completely ignoring avgas and marina blends.
Now, consider the study that was posted here some time ago showing different detergent levels in different Top Tier stations, and other stations, as well. If it's all the same gas in a market, that shouldn't occur. Then we have Costco in the States speaking of providing extra additives on demand for a fee.
Beyond that, up here, our ethanol regulation allows some pretty significant blending differences in premium fuel. Petro-Canada, Shell, and Esso (all Top Tier) claim no ethanol in their premium, as does the Co-op (non Top Tier). Husky/Mohawk (non Top Tier) offers two levels of premium. The 91 octane stuff seems to be ethanol free, whereas their 93 is a blend. Incidentally, that company has been doing their own thing with ethanol content long before the government got involved and long before anyone else up here considered adding it to gasoline. They specifically advertised and offered E-10 when no one else was doing it.
So, oil companies have patents on certain additives. There is a refinery here that does direct deliveries. One company was doing their own ethanol blending before the government even thought of getting involved. Another company virtually refused to buy gasoline from other entities. Some gasoline runs very poorly in my experience, even when it's ostensibly been delivered by the Shell distribution network. That's all pretty remarkable for a completely homogeneous commodity, isn't it?
