so i put 11.6 gallons of gas in my car i got about 265 miles out of it so about
22.8 miles to the gallon give or take a couple miles.

 

Tom and Ray think it's BS

It can't really give you better gas mileage, it doesn't make any sense.

So what are you saying,Im talking bout the 22mpgs i get,as to what it rated at which by the way is 20mps in city and 27hwy,then again i caould also be BSin that :censored:

 

Wow. I get 26MPG sometimes, with regular air in my tires. Does that mean my air here in CA is better than your Nitrogen in CO? No. It doesn't matter, it cannot give you better gas mileage.

And by the way, the EPA ratings are BS. They barely ever correlate with actual mileages.

I can get my mileage as low as 17MPG if I floor it all the time and drive only on surface streets. Or I can get 26+MPG if I accelerate slow and drive mostly on freeways. The way you drive and the places you drive matter, what gas is filling your tires does not.

 

I understand that but explain how i drive to work in the same amount of traffic every day but now i have more gas now than i did before,its not like im saying its a huge diffrence but a littel is still alot.I drive the same way also i dont change the way i accelerate.

So if the air does nothing for you why do people say maintaining air pressure helps save you gas.

Im not talking about a huge dirrence here im gas mileage,im talking about a littel.

 

A friend of mine always used to fill his car at the Tahoe City gas station even though they are relatively expensive up there. His reason: the car always got better mileage after filling up in Tahoe. We burst his bubble when we pointed out that the journey from SF to Tahoe involves a 5,000 ft ascent, whereas the return journey is cruising downhill.

 

They say that because having the correct air pressure does matter. Which gas is creating that pressure does not matter. That's why Nitrogen is no better than regular air (as long as your regular air isn't full of water vapor, but that's easily avoidable). If you check your tire pressure once a week or so, or when you fill up your tank, and you always keep it at the appropriate pressure, it does not matter if you use Nitrogen or regular air.
