I heard that the only reason they put any "additives" in gasoline is to differentiate it from the competitors; that means, it's all the same basic gas, with drops of this or that in it to make it easier to pick out when pumping it into the trucks.
There's not enough of anything in there to warrant the claims...it's all marketing.
At least, that has been the US perspective.... I can't see the Canadian side being that much different.

As for the nitrogen in the tires,if you spend any time on the track,you will see a benefit there,for street use,its just more useless hot air...

78% of the air you pump into tires is nitrogen, so in theory if the justification is that it's the oxygen that leaks out, after filling up any pressure loss, you will eventually have namely nitrogen inside anyway. It is bunk the way it is marketed.
The true benefit of nitrogen is simply this: it contains almost no water when put into the cylinders at 3000psi. In normal street use tires, you will never get them hot enough to turn any moisture inside your tires into a significant amount of vapor (and hence an increase in vapor pressure). We had to switch to nitrogen on my bias slicks because bias tires like to balloon out when the pressures build, and you lose the nice flat contact patch that you want for grip. This was specifically to make sure that the tires did not contain excess humidity that would have gotten pumped in from an air compressor. I put a big desiccant tube (filled with moisture absorbing pellets) in-line with my home compressor for this and air tools that are sensitive to moisture. (and there is a LOT of moisture in that air, just open the drain valve on the bottom of a compressor!)
