The reason mpg's are improved is because nitrogen leaks out of the tire more slowly than regular air so it maintains proper pressure longer. However, if you check your tires at least once a month (which no one does, but they should), you can maintain proper air pressure and it only costs 50 cents at the air pump to do all four tires. Nitrogen can run anywhere from $2 to $10 per tire!!!! You gotta save a lot of gas to make that up.

You can improve your gas mileage slightly by increasing the air pressure in your tires. Another way of saying this is that if your tires are under inflated you will not get as good a mileage.
Whether you have nitrogen or air (which is 78% nitrogen) in the tires is of no importance difference at all.

I have heard stories of 1 to 2 mpg. I wonder if the cost justifies the use. Get the cost of filling tires with nitrogen down and we may have another way of stretching gas supplies.

Yes, but theres not a very significant change. The reason it is better MPG, is cause its slightly lighter than outside air, (Air is 70% Nitrogen 20% Oxygen and small percentages of argon and co2) So it lifts up the tires more. If you were to use helium, or hydrogen(this would be dangerous) it would be even more of a change.

I've heard this, but haven't tried it yet.
Supposedly because nitrogen doesn't expand or contract like outside air does because there's no humidity in it, it keeps your tires at a constant inflation rate, thus aiding gas milage.
But the tiny bit it will save you in gas, you'll spend twice as much for refilling your tires because you can only get it at a certified dealer/repair shop.
I just don't think it's worth the added cost.

Very little, Better off keeping track of inflation in tires. Nitrogen leaks out a little slower!

the title article on yahoo says 3% if maintained
but where do you get nitrogen yourself, you'll always be overpaying at tire dealers
just an opinion!

Your car as it was new, is as efficient as it will be. You gotta keep your tires inflated properly, and your car clean (less wind resistance). Dont waste your time with higher octane fuels, as all you'll be doing is throwing away money.

We changed our car over to it and got two more miles to the gallon.
