    I am not familiar with the nitrogen claim, but addition of nitrogen gas would add nothing to fuel performance. Any nitrogen added to gasoline would eventually equilibrate with air. On the other hand, addition of a nitrogen containing hydrocarbon, such as TNT, could modify the performance of the fuel
    I did a quick search using Google and found that Shell and others claim that the nitrogen (in whatever form it is introduced as an additive) is for the purpose of being a detergent to keep valves, and ports, and pistons, etc free of carbon deposits. They were not at all specific as to what compound of nitrogen they were using or how much.

    But...
    The most revealing reason behind Shell's efforts to push nitrogen-enriched gas might be its decision to suspend research on alternative fuels.
    In March 2009, Shell announced it would hold back indefinitely on funding and research for solar and wind power. Hydrogen power was given the boot, too.
    Analysts cited recent drops in oil prices and an economic downturn as possible reasons for the move.

    Speaking of googling... Here is an interesting overview:

    Negatives regarding Shell's Nitrogen Enriched Gasoline

    Michael Berenis points out there are negative discussions regarding Shell's new Nitrogen Enriched gas. Forum writers point to Shell's skimpy press release as proof that the new gas is mostly marketing hype to increase sales. One science forum goes as far as to say the gas is bad for the environment. But as with most forums, there are positive and negative comments. Until an independent study is released, most discussions are speculation.

    Best Practices regarding Shell's Nitrogen Enriched Gasoline

    Tom Johnson, a self proclaimed Ph.D. Organic chemist with 28 US patents, states that the additives in gas create engine deposits. These deposit are different than deposits left by gasoline. Each brand's gasoline additives are comprised of different chemicals. For best overall engine cleaning, Tom Johnson says you should change your gas brand every 5,000 miles.

    Conclusion to Shell's Nitrogen Enriched Gasoline

    Overall, does the new Shell Nitrogen Enriched gasoline make a difference in the performance or longevity of your automobile's engine? Currently, there is not enough independent evidence to make that conclusion. For now, you can be the judge and see how Shell's Nitrogen Enriched gasoline impacts your car's performance.


    ...and here is everything you ever wanted to know about nitrogen. From fish tanks to filling tires.
