Anyway, I am always using Shell's V-Power Racing which is (supposed to be) 100 octanes. The normal V-Power is 95-98 octanes, at least here in Greece.
Your octane rating system is different than in the US. 98 in Europe and other parts of the world using the RON system are equivalent to 93 in the U.S.

The best we can get here is 100 octane (RON), nothing goes beyond this in the streets

This posting may also vary from state to state and may not be present everywhere.

The ethanol question is another good argument for buying only Top Tier-certified fuel. One of the standards is no more than 10% ethanol.

I hope no one believes the rather irresponsible posts above about E85 (85% ethanol). Check your BMW owner's manual, which states up to 10% is OK, but anything over is not. Only certain cars, including many GM models have been modified to run on E85. There are no BMW models certified for E85, at least not in the U.S.

It doesn't matter what "off-brand" tanker delivers it to whatever brand station. The only thing that is supposed to happen when the tanker is loaded is that the appropriate detergent additive package is added if it is destined for an Exxon/Mobil, Shell, Chevron, Amoco/BP, or whatever station.
You keep saying that, but I think you have it wrong. I live in Texas and work in the oilfield. The majority of the large refineries in the US are owned by large IOCs (Independent Oil Companies - Exxon, Shell, Chevron, BP, etc). They make refined product available for other vendors. This is where the problem is and why I made my comments about off-brand trucks at "brand name" stations. If I happen to see Joe's Gasoline truck at the Shell or Chevron station, I get concerned (especially since I live so close to the refineries).

Here is a list of refineries for reference.

So what is your point? What do you do in the oilfield?

I said exactly what you said -- that all refineries make product for all brands of fuel sold retail, and it is all the same coming out of the refinery. The only thing that differentiates the brands is what additives are added upon loading for delivery.

That is exactly the point. It doesn't matter what tanker delivers it, and whether it has a Shell logo or that of an independent.

Of course, one must assume that the independents who have contracts with brand stations are being monitored for quality control in their additive mixtures. But, the same can be said of the employees driving tankers with major oil company logos.

How do you know that an employee driving a tanker with a Shell logo is any more diligent than one driving an Acme Oil tanker? They both must be counted upon to properly ensure the right additives are delivered to the appropriate brand.

My point is that there are two seperate petrol products coming from the same refinery. The Shell or BP refinery also further processes (mixes its special additives) the gasoline at their refineries. So "Shell" gasoline is different than the gas sold to others. Shell or BP or Chevron have their own trucks for getting fuel to their retail outlets. Shouldn't be Joe's Gas on the side of the truck delivering to a Shell, Cheveron, BP, etc.

Gasolines for other retail outlets are made availabe (as you describe) through various distribution networks (trucks, pipeline, storage, etc). This gas meets basic standards. Retailers of this petrol are free to add their own additives or use methods to lower the overall cost per gallon (this is cheap gas...the kind you put in your car and notice a lower power output or lower mpg).

I work in the upstream side of the business in formation evaluation. This is where we use tools to determine the petrophysical (where is the oil, gas, or water) and geological properties of a well that has been drilled.

What you say above is far from the norm for most parts of the U.S. I realize there are oil-company tankers that do service some stations, so it may be more convenient for them to mix additives in storage tanks at a particular company-owned refinery.

That may be more common in the Houston area, but there are many parts of the country nowhere close to a refinery, much less likely one owned by a particular oil company. Those areas are served by retailers (franchises purchased from major oil companies) who must contract with independent delivery companies to stay supplied with product. Most fuel in the U.S. flows through a national system of pipelines such as Colonial Pipeline, and fuel for all brands is stored in generic tank farms operated by companies such as Colonial. That fuel must be tanker-mixed, and there are nowhere near enough Shell-owned tankers to supply the number of Shell stations in the U.S.

These franchises are required to meet the specs of the brand, and they are monitored by the oil companies to ensure those specs are being met. It doesn't matter whether the additive packages are mixed in the tanker or in a storage tank at the refinery.

As I suggested in my previous post, you may have a point IF that point is there is reason to be concerned that tanker drivers frequently omit the addition of additive packages. I've never seen or heard of any evidence that this is the case.

I've purchased Shell almost exclusively at the same franchise near my house for the last 12 years. That station is supplied by an independent, and I've never seen a Shell tanker anywhere near it.

How do you go about getting the fuel at a particular station analyzed?

in CA you can call department of weights and measures - and theyll send someone out

in europe I was always taking my gas at Shell .. mostly because I had their rewards card so I got a tiny bit back ... and I always though they are the better quality gas.

I'm torn about the fuel here in SF, was thinking to go with Shell too ... but I've read good stuff about Chevron too.
