Good post dude, ive learned about "toptier gas" in school...Hopefully its read like all the other posts of why not to use the wrong fuel....

Only Run 93 nothin less !!!!

My Father had a VW shop for 30 years and i seen the cars that people ran 87 in and the cars that ran 93

First start with, the cars that ran 87 we replace a lot more senors (knock Senors) and others


Cars that ran 93 we did not see much in the shop just for PM services


Plus how much does it really cost to run the 93 then the 87 mabey 5.00 dollars more at the pump to run the better stuff!

Just my 2cents

When I ran 87 instead of the recommended 91 in my old ls400 I could tell a major difference in horsepower. I run 89 in my hemi, but I have ran 87 in it before and I could barely tell the difference.

I started using 89 octane as recommended by the manual and then after a few fill ups, I switched to 87 octane and didn't notice any difference at all.

There are a few facts about gasoline that make whether you buy it at a name brand station or not almost irrelevant.

First, all gas is generic as it leaves the refinery. There may be differences due to local requirements due to season and pollution control requirements, but all of the refineries are dumping their output into the same pipeline distribution system. The output of a Mobil refinery gets mixed with the output of a Citgo refinery and etc. Here in the Chicago area we have 3 refineries that make the blend required for the local pollution control rules. A Citgo in Lockport, IL, BP in NW Indiana, and Exxon/Mobil in Joliet, IL. All three get the bilk of their crude in via pipelines primarily out of Canada. All three ship their output in the same pipeline distribution system. So up to the point where the big tanker truck picks up their load to deliver to your local fueling station, all gas is exactly the same.

Next, at the point where that tanker trailer is making its pickup, here is where the difference comes in. They put in the proprietary additives unique to each brand. The difference could be as little as a quart of additive in a 10,000 gallon tanker. So that tanker picking up a load for a Mobil station is likely carrying fuel that was refined at a combination of different companies, just that it contains the additives that are specific to Mobil. This is also the point where the ethanol is blended in. Ethanol cannot be transported via pipelines due to its propensity to pick up water. It is usually shipped by rail.

So the next time you think that one brand of fuel is better, just remember it is only the additives poured into that 10,000 gallon tanker that are different between brands. For me, if the Shell is 5 cents more than the Speedway or Sams Club, I'm buying the Speedway or Sams club and won't give it a second thought.
I think you may have some of your facts confused. There is no sharing of refined petroleum products between major oil producers. Some of the refineries you may be referring to may receive their raw materials from the same distribution system but once that raw material is refined into fuels and other products there is no collaboration between petroleum producers. There may be one major producer such as Shell or Exxon/Mobil may refine products for a variety of retail locations such as Seven11 etc, but major oil producers do not share refined products for sale at their retail locations.

One circumstance Shell sold some inferior gasoline which clogged fuel systems in many vehicles in my area, this was only experienced by Shell customers. More recently Petro-Canada, another major producer had some problems with their refinery in town and ran out of 87 octane gasoline was not selling any regular gasoline at their retail outlets and were unable to provide any of their other customers with fuel for a few months.

That may or may not be true, having been in the oil/gas industry myself, even working directly on some of the drilling platforms, there is a lot of collaboration between major oil producers, and in many instances, several companies own oil rights in certain areas of the Gulf of Mexico for example, it is not impossible but rather highly likely that you will see more than one major producer owning partial shares on ONE lease (which may contain several platforms/wells), and even operating off of some of the same platforms. Reason being, there are only so many leases available, land or sea. Same is true for pipelines, there are only so many miles of pipeline available to ship crude oil in and refined product out. Basically, average folks, those that don't work directly in the industry, don't see the combined effort, just the competition between the brands.

By the same token, there are only so many companies that have the capability of refining crude oil into the usable products we pump into our cars and trucks. Despite the fact that it is technically an Exxon/Mobil refinery, there are other oil companies that own a stake in that refinery as well. These are typically your smaller, no-name companies no one has ever heard of that do not have the capacity to drill or refine the crude on their own.

After the refining process, finished product is then shipped off via pipeline, barge, rail/tanker car most often to storage terminals, there again operated by more than one company for later sale at their retail locations.

Basically, I agree with MikeD simply because the crude coming into the refinery is the same no matter which company operates the platform, the refining process is the same, so the end product is the same. At exactly which point in the process the different additives used by different companies for different markets/regulations etc., are added is a good question that I would like to look into further myself, but essentially, there are limited production/refining/storage and distribution systems in place for refined petroleum products which pretty much necessitates some collaboration on the part of oil companies, so the gas you buy from the Shell station could very well have originated from a BP platform, processed at an Exxon/Mobil refinery and so on.....

For the record, I have only run 87 octane Exxon/Mobil products in my vehicles. It was only when I ran the same grade but went to a variety of off-brand stores that I experienced problems, just my experience.
