i keep hearing about people putting nitrogen in their car and how its a million times better than regular air that you get at the gas station. i was wondering is it worth the $20/avg that shops charge to fill up your tires?
Thanks for the article. I was really debating doing this to my car but you just help me save $20. Its not a lot but still thats $20 I can put towards something else. I'd just rather regularly check my tires pressure and refill it for free.
