Green Valve Stem Covers

You really should replace the green valve caps with black ones, it might keep others from asking useless questions.

I quite frankly prefer my OEM black caps.
Nitrogen or air they can fill as they like and I will ignore and top off as needed with regular compressed air.

HAHA, NO!

No, a green cap means nothing.
Slime used to give green aluminum caps with their Slime sealant product. It is green because their slime and their logo is green.
I do not think nitrogen has a color, and am sure if it did that green is not the color.

You can get plastic or anodized aluminum colored caps in almost any color now. What do all those colors mean? Nothing. The pope's red shoes do means something, but unless you want to vomit I would not look into that....

"Helium and hydrogen are way better. They will even make the trailer a few pounds lighter."

How many pounds? lol

I installed an oversized blinker fluid reservoir so I con leave it on for lots of miles.

Be sure to also check your blinker fluid before you hit the road :)

Helium and hydrogen are way better. They will even make the trailer a few pounds lighter. Hydrogen will give the best BANG for your money.

The green stuff is the magic gas!

Sorry I forgot to add the winker to indicate sarcasm ;)

Since O2 and the rest bleed out so quickly virtually all tires have just Nitrogen. Molecules are the same size so it must be some voodoo power of the green cap.

well oxygen molecules are slightly smaller than nitrogen, even though atomic weight is higher. So tires will loose slightly less pressure but not much. And with todays tire construction it would take a LONG time before all the oxygen bleed out.

Really all a dry nitrogen fill does is eliminate water vapor which can go from gas to liquid and have a bigger pressure change effect. For those us where a few PSI is no big deal, no problem. Could do basically the same thing with plain dry air. All gases obay boyles law for pressure vs. temperature.
