It’s all about Nitrogen

It keeps the tyres cool on highways. It escapes the tyres slower than air because its molecules are bigger. So I have been filling the tyres with Nitrogen. I shifted my loyalty to a Bharat Petroleum filling station from my trusted HP fill stations because of Nitrogen filling. Even though it’s no longer convenient to tank up at this station after a change of job last year, I continued to visit this one for the free Nitrogen.

Recently, I found an HP with free Nitrogen in the other direction with less traffic and I thought I could shift there. So if you own a fuel station, provide free Nitrogen filling because customers like it and they will come to you for it.

But…

I started thinking if I really need Nitrogen. Have I seen the benefit of Nitrogen after all these years? Not really, except for a peace of mind and the satisfaction that I seem to know and care about automobiles. After watching these two videos on YouTube, I have a change of heart. I don’t think I will really need Nitrogen anymore.

The air around us is already 78% Nitrogen. Race car tyres are filled with pure Nitrogen to avoid an unpredictable increase in tyre pressure. With Nitrogen or Air, there will be pressure increase with the rise in temperature. With air, there’s a chance of moisture presence which can lead to an unpredictable rise in pressure. Hence, race car tyres are filled with pure Nitrogen. How about the Nitrogen from the fuel station or tyre shops, is it pure? Probably not.

Bottom line: Unless it’s a race car, don’t botter.
