this is true I do it at work

 

haha maybe you can even fly

 

Replace the helium with hydrogen and valve stems with spark plugs and I'm sure he could.

 

Costco uses nitrogen when you have tires installed there. Doesn't cost extra and I believe better than using air imho. Call first to make sure your Costco does.

 

The nitrogen has so little benefit over air that there will be no noticable difference unless you are pushing the limits of racing the car. And even then, unless you've got a nitrogen tank on hand, being able to increase or decrease the pressures at will is going to be more valuable.

 

We use alot of either CO2 or nitrogen in the off road arena mainly as its a convienent portable source of gas for reinflating tires. We typically need to run at 7-10psi off road and then air up for the road. Neither gas will hurt your tires or put you in harms way and frankly, I'm thinking about changing careers after reading this. $65 bucks for a fil lof 4 small car tires is hugely funny - I can refill my 40lb bottle with CO2 for $8.50 and that will refill all the tires on my Jeep, trailer and Suburban at least twice.

If I were at the track, I would carry a bottle for the car but for regular road use, its a complete waste of money and time IMO....stick to good ol compressed air.

 

I'm mad now. They put synthetic oil into my engine at my 3750 mile/6-month oil change.

The oil change turned out to be 55 bucks instead of 35, because they are using synthetic.

Firstly, I don't want synthetic before 7,500.

Secondly, they didn't tell me about in the beginning. They only called me during the day, when I lost my cell phone and don't have access to my voicemail. Can't really complain (and ask them to take it out) or sue them since they technically called me.

Nevertheless, this dealer is on my $#!+ list.

 

I wouldn't bother with the nitrogen fill unless I was going to do some serious performance driving like autocross or road racing.

The idea is that water vapor expands and contracts so your pressure varies with temperature. Rule of thumb among the local autocrossers is you get 2 PSI increase in pressure with each 10
