Shell has been advertising it. I think it is marketing bullcrap, like all these "it wipes 'sludge' off your engine!" stuff people advertise. And expensive you should be able to tell if Shell gas costs more than other, conventional gas.

I thought Nitrogen was completely inert, what good would it do in a gasoline engine?

When we tie into a gas line that is NG or propane we run Nitrogen through the line (after shutting the gas off ) as we are welding.....no flare ups.

 

It's supposedly be better than their old formula in cleaning and keeping engine maintained cleaner. The shell gas in my area are the same as Chevron and Mobil 1. I never put in 76 gas for some reason. I change it up though, but I'll stick with Chevron and Mobil 1.

My choice of gasoline pumps:

Chevron
Mobil 1
Costco Gas
Sam's Club Gas
Shell
76
Valero :lol:
Arco (Haven't fill with Arco for 3 years)

 

I never put in 76 gas for some reason.

What's wrong with 76

 

I can't figure out why nitrogen would be used either. Wouldn't added nitrogen add to the level of nitrogen oxides emitted during combustion? Doesn't make sense. I'll have to ask my brother-in-law...he'll know....

Sounds like baloney. As was mentioned, Nitrogen is an inert gas, meaning it doesn't burn. So why would you put it into something that's primary purpose is to be burned? They say it's supposed to clean "gunk" out of the fuel - so why don't they filter their fuel better before it gets pumped into vehicles?

 

Technically nitrogen isn't even inert as a gas (that term refers to things like argon and helium that hardly ever form chemical compounds), but they're not putting N2 gas into their gasoline. They have modified the usual detergent to include some nitrogen atoms in the chemical structure which supposedly makes it a little more effective in the harsh environment inside an engine. The Shell compound has the same function as Chevron's 'Techron', i.e. keeping the engine cylinders as clean as possible - which is not really a function of "gunk" in the fuel, but of the byproducts of the combustion of the fuel. The detergents also reduce deposits from forming in the injectors.

I have no idea if the stuff actually works any better. But a friend of mine was a chemist at Chevron and I know he sometimes tested the Shell product (and others) and did some comparisons with their 'Techron'. They seemed to be in pretty constant competition to keep improving their detergent properties in response to new detergent formulations by other companies.

 

From my brother-in-law the chemical engineer and uninstaller of MTBE in California refineries:

The short answer: "nothing". Nitrogen is an inert gas that does
absolutely nothing to enhance the gasoline's ability to burn. "nitrogen
enhanced" is just a fancy way to say that they upped the amount of
detergents in the gas (many are nitrogen-based) to make engines cleaner
and to prevent build-up. This has been used for years, but some major
oils (like Shell) are increasing the amount (in Shell's case they now have five times the government-mandated amount) in order to work
better in new direct-injected and hybridized engines.

 

I've cut pipes with an Oxy/Acetelyne cutting torch with Nitrogen running through it (cutting into a gas main)...that passes my inert test :lol:

 

I presume you also use that torch in the normal atmosphere which is 78% nitrogen.

If it were inert we wouldn't have a problem with NOx emissions from our cars.
And many nitrogen compounds are very far from inert - Tri-Nitro-Toluene (TNT) comes to mind, as does Nitrogen Tri-Iodide which explodes on contact by just about anything. Makes an interesting fly swatter if you put it near some honey so the flys land on it and set it off.

But the nitrogen in Shell's gas is not being put in there to increase its energy but rather to improve the detergent properties.

 

I can't remember the last time I saw a 76 station. We have, Exxon, Valero, Citgo, BP and Shell around here. Shell is always higher $$$.
It's too bad about the 76. They were full service. A guy actually came out, pumped your gas, cleaned your windsheild , checked your oil and tire pressure. And took your money , of course! Probably the last of it's kind.
Well, I'm disappointed about the Nitrogen Enriched Gas. Thought I was gonna get more boost for my boost.

 

When I'm not buying gas on base I use the 76 station down the highway. They've got the cheapest gas prices for ten miles in any direction.

:thumbsup:

Come on out, Russ, I'll fill your tank up with 76...and I'll clean your windshield for old times sake, buddy....

 

Watch out, I just may take you up on that. We can go out to the clear desert skies,bust out the scopes, eat steak chili and fart all night!

 

Holy s***! Have you been watching me out there?

:lol:

 

NEVER heard of 76. Is that a nickname for something else or is it similar to our Route 66 stations in Texas?

 

Same company different brand.

 

If I'm desperate, Turkey Hill (local convenience store chain), but ideally either the local grocery store or Citgo as they are the only ones that sell normal gas anymore around here. We have a couple Hess and Valero, but most of those are either out of the way or high. Most of the Exxons and Sunoco have closed up shop over the past year or two. If I happen to be down near the Maryland-PA border for some reason I'll top off at Royal Farms due to Maryland gas being a lot cheaper than PA gas.

 

I have a lot of turkey hills around me, where are you from?

 

Union 76, Conoco, Philips 66 are all the same company.
