Changed the oil today. Previously had Penzoil Ultra. I saved the old filter which was in good shape but the oil was filthy black. Put in Mobil Extended Performance with AC Delco Filter. Rotated the tires, filled them with Nitrogen gas, reset TPM and OLM. Good to go. The earpiece on one of the headphones pulled out with the wire exposed. Dealer replaced under warranty. :thumb:

Caution : With the Nitrogen and Penzoil Ultra, your gas mileage will be so high that you may end up having excess fuel pouring out of the gas filler neck. Don't throw out any lit cigarette butts.

;D

Hope they didn't charge extra (or more than 10 bucks) for the nitrogen..

 

[wbassnp007]

I did pay a little extra for the Nitro Fill. I provided my own oil and filter. They only charged labor. I requested that the mechanic wait until all of the oil dripped out before putting back the drain plug. I also requested that the drain plug, lug nuts, and filter cap be tightened to the correct torque. I actually listed the numbers for them.

I'm glad that you are getting good mpg.

I can understand paying a little for the first nitrogen fill, (because they have to bleed the air out of tires first if they do it right) but for subsequent air-ups I wouldn't pay a thing. After the initial fill they won't have to add more than a pound or two if not less....and every time you take a deep breath you're getting 78% of the magical stuff they put in your tires.

They said that any additional top off would be free over the life of the tire.

Like you said, the air we breathe is about 78% nitrogen. They explained it this way to me: The reason air is such a poor inflation gas is that it contains about 20% oxygen. While oxygen is essential for human survival, it is harmful to just about everything that is not a living organism.

I hate to argue with your "experts", but, as I understand it, the advantage of Nitrogen over Oxygen, is that Nitrogen is a larger molecule, and is slower at escaping through the rubber in the tire.

This is my understanding as well!

Oxygen is a component of water (H2O) and the catalyst of oxidation (rust, corrosion, and rot). Without the presence of oxygen, there is no opportunity for rust or corrosion to occur, or condensation to form. More importantly, as you stated, oxygen has a very small molecular structure. So small in fact, that it is normal for air filled tires to lose approximately 1-3 psi per month from permeation (the process through which the oxygen molecule in compressed air seep through the carcass of a tire). Nitrogen, on the other hand, has a very large molecular structure and the use of nitrogen can eliminate pressure loss from permeation.

So we agree...

If air is escaping through the rubber of your tires...you need new tires. The main reason to use nitrogen in tires is because it is more temperature stable than the mix with oxygen + other trace elements. It is used in racing because it makes adjusting psi in very small increments possible, (to affect handling) but for passenger vehicles that rarely go above 70mph (on a straight highway with no sharp corners) the benefits are less clear. Like I said earlier, nothing wrong with putting nitrogen in your tires, just don't fall into the trap of paying for every air-up.

You are supposed to get a free membership in the NitroFill Auto Club providing free NitroFill top-offs, inflation service reminders, 24 hour emergency road service, emergency delivery, emergency battery service, lost key or lockout, travel benefits, theft and hit and run protection, trip routing, and trip interruption coverage.

I agree that it would be a rip off to fall into the trap of paying for each additional top off of nitrogen gas.

Humph - "Well, just as gases can permeate the membranes of the body, air can and does permeate the rubber in tires. Air molecules literally find their way out of the tire – slowly – resulting in a gradual loss of air pressure."

I guess we all need new tires, then...

So does NITROGEN

 

[MOCHA11NOX]

Well, I've been using CO2 for years...carry a "bottle" of it in our Avalanche

The expansion ratio of Liquid CO2 to gaseous state makes carrying a 10LB
bottle quite economical and extremely long lasting.

Plus I can use air tools if I need to change a flat

and/or

I always have a supply of pressurized "air" at home to check and fill any low tires
at my convenience...not someone else's...

Out of bounds - awesome. You are over the top.

The key is..slowly...as in very slowly. Most of your air loss comes at the rim which has a lot of surface area and never has an absolute perfect seal. There is a legit reason to use nitrogen instead of regular air, but that isn't it..

Would so the tire dealer could make more money be one of them?

 

[grometsc]

That is the biggest reason...its pure profit!

OK, help me out here. Why should I switch to nitrogen? I have never had a tire rust, corrode or rot, the tread wears out..not the sidewall. Will I get a better ride? Will I get better mpg? How much? Seems inconvenient since there are air stations all over and not so many nitrogen fill places? My tires on every car I have owned and a motor home never need more than 1-3 psi over several months...and most often not that.
