I usually use Hugo Chavez gas, but when I fill up with Shell, it really does seem to make the engine smoother at idle and cruise.
Do you think it makes a difference? Anyone else notice this? |

I'm sure it's just some additive or process all the gasoline brands use, or use something similar. Except they're just advertising on it.
Like in the first season of "Mad Men" when they're struggling with the new rules about tobacco advertising trying to keep the Lucky Strike account happy. And they come up with the idea of saying "It's Toasted". The tobacco magnate is confused, "But everyone does that!". And the ad man says, "Yes, but you'll be the first to say it." My cynical side says it's something like that. |

Quoted: Quoted: idk for sure, but I would think that adding an inert gas to my fuel would decrease it's btu's per gallon, i.e. sounds like a scam to me. Nitrous is mostly nitrogen. This stuff is supposed to clean your engine though. the nitrogen doesnt do anything, its a vehicle for adding oxygen. hence its full name... nitrous oxide. |

Probably bullshit.
Its not gaseous nitrogen –– N2 has a triple bond and is chemically inert. They're probably referring to the nitrogen in "amine" molecules, such as polyether-amine. (Which is the same as Techron, I think). Its just another way of describing high detergent/solvent gasoline. |

Supposedly, it's a detergent that doesn't break down in direct injection engines and reduces soot buildup.
Whatever it is, my truck always gets the best mileage on Shell gas. It doesn't have a knock sensor, so quality differences between brands are pretty obvious since it will ping on shitty blends. |
| I have read this discussion on this same site before, and the conclusion by our local chemists was that Shell was using an additive in the gasoline that had a nitrogen molecule in it. The additive was very far removed from being simply nitrogen, and the marketing department went wild with it. |
