Chevron Techron vs Shell Nitrogen Enriched?

From a "tune" perspective, does the tune account for the fuel type? I suppose that in a technical sense it does but since the fuels are so close to each other prior to additives then it is a moot point.

This is also what I have read from a chemist. He claims alternating additives cleans the engine better and mentioned Shell and Chevron/Texaco specifically. That is what I do.

Fuel is Fuel.
All fuels come from the same pipe lines to the distribution terminals, tank farms. Then loaded on tank trucks and delivered to stations.
Top tier fuels are just additives.
Just buy the lest expensive fuel from a high volume stations to get the freshest fuel.

Ph.D. organic chemist here. Shell certainly does not add molecular nitrogen to the gas. It is the common, casual, and often unfortunate parlance when marketing chemistry, to refer to a chemical compound by its most interesting, expensive, reactive, or sexy element. I think that's what's going on here; it's a molecule that contains nitrogen and performs a certain task.

Sure nitrogen at the elemental level can be combined with other elements to create molecules that will actually do something for us, so I'll give them that credit, if that is what they are doing. But they advertise they are using nitrogen (N2) by itself which can only serve to take up space, therefore less gas for more money...but its a gas at these temperatures so it would simply vaporize away. N2 at liquid is -320 degrees and its obvious they aren't doing that. So sure, I have no clue what they are doing or how they can claim it helps us. Shell openly posts on the pumps they are using ethanol so how it meets the top-tier fuel requirememts is beyond my understanding.
Friend of mine who lives in Fla. told me he had switched to Shell for his 02 vert and after a tank of two his mileage went back up to 25 from 23 average. He keeps meticulous records so I believe him. I tried a few tanks here in Flagstaff and found no big difference.

Same here. I used to only buy Chevron with Techron, but all the stations closed, so I now only buy Texaco.
I think GM used to use only Chevron gasoline when testing the Corvette.
Most people report that besides keeping injectors clean, Techron also does the best job of keeping the fuel gage working.

and remember that the terminal storage facility injects the additive at a pre-determined treat rate thru solenoid activated valves that are not always calebrated regularly. Top Tier is just a higher treat rate. Each tank farm stores propritary additive for each brand of fuel that they thru-put. EXA. BP is invigorate, Shell is Nemo with nitrogen, Phillips is Hitech and so on. So I agree buy the freshest preferrably with out ethanol..

who knows if that still applies or not. i think that wisdom dates back to the leaded fuel days.
