Shell Nitrogen-enriched Fuel???

[Juhsga]

Does anyone have evidence through Scientific analysis that Shell's nitrogen-enriched fuel does in fact do what it claims.

I have worked with nitrogen in displacing oxidizing Oxygen for the use in electronics and even for filling rubber tires. But from my experience the use of nitrogen dries out tires way more quickly and leaks much more rapidly than oxygen. So with that in mind, what would be the effects of nitrogen-enriched fuel on seals and gaskets?

This is not Nitrogen gas per se. It's Amines (PEA) in gas that contains Nitrogen.

I know this is anecdotal, but I used to fill up with Shell exclusively. I noticed a large drop in my fuel mileage at the same time as the "Nitrogen-enriched" switchover. Whether that is Shell or the provider I do not know. However, I haven't had any kind of seal or gasket problems using it or since discontinuing its use.

We used nitrogen in the brazing of copper tubing and fittings. U run a light flow of nitrogen thru the pipe u are brazing together and the nitrogen prevents scaling of the copper , which means no contaminates are formed inside the pipe to clog the line ............so I guess it prevents junk from forming on valves and head????????? its my guess

 

[ARCOgraphite]

No. Air we breath is mainly nitrogen - plenty of that going into the engine already. Its in the HC chemistry of the detergent - you have to be a chem-E to understand it. Shell have the little booklet in the shell station to explain it in lay terms.

 

[edhackett]

A chem-E is not required. High school chemistry is more than enough.

It's a silly advertising campaign. The nitrogen refers to the nitrogen atoms in the amines, which are used as detergents, such as PEA(poly ether amine) used in the Shell and Chevron gasolines.

http://en.wikipedia.org/wiki/Amine

Many people think of nitrogen gas(N2), the inert gas that makes up 80% of our atmosphere. As pointed out, that's not the case here. Nitrogen when combined with other elements, particularly hydrogen and oxygen is quite reactive. NH3(ammonia), NO2(TNT), and NO3(Ammonium Nitrate, another great explosive).

So does Shell and Chevron fuel additives work on cleaning valves? I have filled up on Chevron before and I noticed a difference from my usual fill up from my local Sunoco. Looks like these Amines are only used to lower the combusted fuels output of GHGs. Doesn't say anything on the wiki about being used to remove carbon buildup in motors.

For the love of god. Have people forgotten what search is??

Has this not been discussed (and answered) 400 times in the last 90 days.

Shell gasoline is the most expensive in my area even over Chevron!!!!!! Wayyyyy more than Chevron that contains "Techron".

For the money I'd use Shell the least compared to Chevron. Besides one can even buy bargain brand gasoline and buy a big bottle of Techron every couple months and keep the gas treated that way. You can save a few pennies but money is money!!

In a nut Shell!! HA HA Shell gas may be good for ones engine but you need money to buy this gas.

Are you talking about the outside of your tires look drier or the inside. If your saying the outside your tires would be schredding off the rims if they are drying bad enough on the inside to be seen on the outside. The nitrogen is actually supposed to leak less than traditionally filled tires. Though its really rather minor in street use. As far as airplane tires, race cars etc.. which have wide and rapid changes in tempature it keeps a more constant pressure.

As for shell gas I had been consistantly using it for over a year and everything stayed the same before and after for me as far as i could tell and see mpg wise. However I am now using sunoco and i did and am experiencing worse mpg in summer and now in winter as well. The shell is top-tier certified and compared to say citgo, sunoco etc.. is more likely to have a lower sulfer content and better/more cleaners. It also is tested more often and held to a higher standard than non top-tier.

I've tried/used Shell gas before they started advertising the special "nitrogen" enriched ingredient. I too didn't see or notice any difference in MPG or any other.

NOW it is considered to be the most expensive gasoline in my neighborhood and will not consider using it until the price is more agreeable.

I'd rather buy ARCO and toss in a big bottle of Techron every other month.

sucks to be you guys down south, here in toronto (and most of canada) prices are the same at all stations, off brand ones are usually a couple cents cheaper per litre but all the major brand ones (shell, sunoco-petro canada, esso, ultra mar, beaver) all are the same prices within the area.

 

[Durango]

Mau,

Your country isn't as greedy as the big shots in California.

So far gas prices has risen but not as much as it should have. IIt's mostly due to the world economy. As long as it doesn't go any higher than eighty buck/barrel of oil then were OK.

Shell however is a whole different story. Greedy to say the least!! I don't care for that fancy "Nitrogen" enriched gas cuz it just isn't cost effective. Shell has Nitrogen. Arco has "CleanTech" so despite the opinion of how lousey Arco gas is my 01' Durango V-8 AND 08' Impala SS has no issues with this gas. Besides that it's an easy twenty cents lower than Shell.

Based on your pocket book which would you use????

It used to be here that Shell was the highest by about .10-.15USD/gal, but latetely they are level with all the other brands including the some of the discount chains.

 

[Durango]

Part of our problem here in California we pay one of the highest taxes anywhere and still we can't pay our bills!!!!! One of the biggest revenuses is the gas tax.

Still though I can't afford that fancy gas. I'll just buy Arco and put in a big bottle of Techron every other month.

[Turk]

Top 1% pay over 40% of the taxes.

Good luck out there.

 

[[RT] ProjUltraZ]

Nitrogen N2 is 78% of the atmosphere, O2 is 21%

guess what CO2 is? it's killing us all!

three hundredths of 1% in other words, the atmosphere is 99.97% not CO2

 

[Mau]

You guys do know that your prices are still cheaper then most of the rest of the world.

A little conversion (got the prices from http://www.californiagasprices.com/)

You guys are paying about $2.85 per Gallon, convert that in to litres its about $0.75 USD per litre. We up north are paying roughly $0.96 CDN per a litre for regular! on a good day Majority of the $$ is going to the crummy Govt!

And you don't want me to get started on Europe, those guys are getting taxed every which way.

 

[Durango]

Mau,

Buddy your figures are off. In the real world here in Los Angeles the current gas price is about $3.15-$3.20/regular of most brands of gas. The local Shell in my hood is $3.30/regular, $3.35/mid-grade and the big whopper $3.49/supreme.

Again even Chevron is not even close to what Shell wants so what do you think I'm buying? My truck gets the Chevron and my daily gets the ARCO.

Either way I won't try Shell because it's just outta my pocket book. Just wait and see what they want when the gas goes up again.

Lol! Thats because of all the poeple that are on the welfare payroll in the southern half of California. Cut the walfare system, and the state coffers would be full.
