This tread to me is very interesting. The same guys that go bonkers over cutting open filters, and sending oil in for lab analysis - do not care what fuel they use?
Seems a little ironic to me lol
Because anyone who understand fuel distribution understands that it's a fungible commodity. I live in the San Francisco Bay Area, where there are 5 major oil refineries, and all make fuel to the same industry standards. That fuel is transported via pipeline and pretty much traded. It's more like bank/ATM transactions than anything else. Shell deposits fuel into the system, and their customers withdraw fuel from fuel depots. The pipeline operators are only required to "transport" X amount of fuel and to allow their customers' customers to withdraw that amount of comparable fuel at points A, B, and C.
If one is buying fuel in Southern California, there hasn't been a Shell refinery there in years. Shell does have a large distribution facility. It's effectively just a horse trading facility where they distribute fuel made by someone else.
The thing that brands fuel is that it will use detergent additives developed or specified by the marketer.
