Our local garage , a well respected and long established engineering establishment offer to fill your tyres with Nitrogen. They state that this will give longer tyre wear and improve miles per gallon.
Now two things puzzle me, first air is 78% nitrogen anyway and I am puzzled how taking the oxygen and co2 out makes any difference, secondly if it does make a difference why are the car manufacturers who are wringing every small MPG improvement they can find, not telling us to do this ?
The thing is it`s in black and white on the glossy flyer just posted to me.
