It was hit upon correctly, that gas is the same, only the additives may be different. When I would load a tanker, I selected who was getting the gas. The system would dose the gas as it was loaded with the additives that the customer wanted. Now, to that end, all the easily recognized name brands are getting just about the very same gasoline and additives. The only differences are between them and the regional convenience store kind of gas stations, which will only request a very basic, minimal additive supplement.

Just go with the best price you can get your fuel for. Forget the silly nonsense about who has the best gas. It is true that maybe the load the Chevron got down the street got yesterday was from a different refinery, since the terminal may have switched suppliers and the load the BP down the street is different today because of that switch. It jumps back and forth all the time.

Brand loyalty is really something. But a simple look behind the scenes can really be an eye opener. But some will continue to where blinders and claim one brand is better than the other. They just know!


Thanks for the insider info. Shell's gas is nitrogen enriched, in which step does Shell do that? after the gas is loaded to the gas station tanks?

It's a nitrogen-based detergent (as is Techron), not nitrogen gas, which is added at the depot with the rest of the additive package.

I generally use either BP or Shell, as they are the most prevalent Top Tier fuels in my area. I can't tell a difference between the two.

We don't have Exxon fuel here however our esso brand is the imperial oil and Exxon equivalent.
From experience I've tried many different fuels and in my vehicles I never really noticed any difference however my Harley is a different story.
It's got an S&S big bore kit,cams,port work on the heads and they were milled for compression(and to flatten them perfectly)dyno tune etc,etc.
My bike is very picky when it comes to fuel. My bike runs great on shell 91 v-power,co-op 91 octane and petro-Canada 91 octane.
The husky/Mohawk 92-94 octane stuff is hit and miss,I think its dependent on how old the fuel is. My bike also looses 5mpg with Mohawk/husky fuel so I don't bother with it anymore.
My bike pings audibly with esso 91,fasgas 91 and basically every station other than the 3 I mentioned above.
Only my bike pings though,my vehicles run fine on any of the above fuels however I use my bike as the standard and if the fuel is no good in it,then I steer clear of the station/brand altogether.
I suggest trying out both stations and run 3 tanks of each brand and track mileage. Then go with the one that gave the best results.
15 cents a gallon isn't a lot of money in the long run however it is better to have in your pocket than an oil companies.

For all practical purposes, zero difference.
