re: Nitrogen for tires

quote:When talking "bottled" nitrogen as he mentioned (which half the dealerships do, other half are typically N2 generators), the source is industrial liquid N2 compressed into high pressure cylinders. There is no filtering out CO2 when it comes to bottling N2.
I'm curious why he is wrong. The nitrog3n tire compressors sort of do just that.
ETA: I will also add that him saying "air is 80% N2 and they just filter out the Co2 then bottle it"....if they just filtered out the CO2, then the bottle would basically be normal air due to CO2 making up <0.1% of dry air

Correct I missed that.
I have bottled nitrogen for compressors.
Never even thought to put it in my tires.
And honestly it's expensive for what it is.

A N2 cylinder doesn't cost but what, $5-$7? That contains 300scf. I'm sure you can fill a whole bunch of tires with that

Not pissing it away if manual says 89 91. Id alternate and see if you can tell.
When i was a lad our packard liked leaded 98. I wonder what collectors do.

Don’t listen to the Neanderthals, Rooster. Nitro is what race cars use. It doesn’t expand and contract as much as regular air when the temperature changes.
N2 and air have the same coefficient of expansion
1 psi for 10 degrees
there are only 2 advantages of nitrogen, nitrogen molecules have a more difficult type of seeping thru the rubber to the atmosphere and N2 is helps resist rusting or corrosion at the rim seal

have been using premium since getting my latest ride because the owner's manual says 89 or 91, can't remember. Am I pissing away $0.40/gal on the higher octane fuel?
You should use what is labeled under your cas cap. Too lean or rich a mixture can cause issues.
It depends if the vehicle says premium fuel "recommended", or "required". The vehicles where it is only recommended will run fine on regular, the engine management system controlling the fuel injection will determine the optimum fuel air mixture and ignition timing for the engine to run correctly.

Argon or gtfo
For real do, go to airgas or other local gas company and purchase a regulator. Should be be able to get hoses for cheap at Walmart. Full setup might cost around 50$. Gas company will loan you a container after you put down a deposit.

You can buy leaded 100 octane at airports but it's not good for post war cars.

big reason to use Nitrogen is that it is dry.
This. The moisture in the air is what makes the pressure change with the heat of the tire. Regular air compressor with a good dryer will be comparable.

General rule of thumb. Anything gas with a compression ratio greater than 10.5:1 should get higher octane to prevent engine preignition anything lower compression should be fine.
That said most modern cars can calculate the fuel/air mixture and adjust to prevent preignition knock.
