Gasoline additives are molecules, and they all have nitrogen atoms. They are liquids at room temperature. This is not diatomic gas, like you'd find at a welding supply shop. Think nitrogen fertilizer that you'd put in the ground. Just because they contain nitrogen doesn't mean they can't be in solid form.

 

Ya thats what I was thinking, marketing ploy

 

Chevron Techron + Shell V-Power = Vtecron! ftw!

The Only benefit from Shells new formula is to sell more gas!

If it's convenient I go to a local station that has 100% gas.

 

Great article there! It does not say anywhere in it though that Shells new formula is to sell more gas, but it does state what I pretty much alluded to before. His idea of switching gasolines every 5000 miles is completely new to me and sounds interesting.

 

^^I think the article was written Pre-Shell nitrogen gas.

I usually switch brands (Shell - Chevron - Mobil) every 2 or 3 tanks. Hopefully that does trick!

 

About 6 or 7 years ago, Shell introduced a new gas additive in Canada and did a trial rollout in Loisville, KY. Their additive (a friction modifying formula advertising better mileage) damaged cars' fuel systems, and they were sued. They had to rush and pull it from those the markets. Then they rollout V-Power in their premium only that still uses an old technology just at a higher dosage to help keep intake systems clean, but it contributes to combustion chamber deposits. Now they introduce another old technology amine additive modified in a way that has more nitrogen which they advertise ("hydrogen, nitrogen, what's the difference, it's all good green stuff"). In all this time, their additives have never been the equal of Chevron's (who invented the "nitrogen-enriched" amine-based fuel additive), especially in regular and mid-grade. Amoco used to have a proprietary low sulfur premium that really did reduce SOx, but new EPA regulations have reduced everyone's sulfur levels to that level.

I'm not a fan of Shell due to their dishonesty, but using them won't kill your sled.

 

Remember too that "Top Teir" is a club, not a certification. I'm willing to bet BP and Marathon make a quality product with good additives, but they aren't on the list.

 

Ethanol in our gasoline is yet another government scam and really isn't all that great for our cars for those of us who plan on keeping them around awhile... A local mechanic who seems to know what he is talking about is a believer in Amzoil products (I'm sold on their oil)... he advocates the use of adding about an ounce of a synthetic two stroke outboard motor oil to five gallons of gasoline to counteract some of the long term effects of running alcohol in our cars... I've been doing it in my old Toyota pickup truck and, maybe I'm easily hyped, but the milage seems to be up a bit and theoretically, I'm providing some protection to the fuel pump, injectors, and some of the plastic/rubber components. Anyone else heard of this idea?

Shell was once rated as one to the top tier gasolines... I try to stick with Shell or Chevron....
