Oil; I'll bite: my m54 just turned 200 and I'm switching to 5-40. Wife's N63 is 85,000 and sticking with 5-30.

There is very little difference in the weight of Nitrogen and air. It's not enough to use it to reduce unsprung weight. The racers that use nitrogen in their tires use it because the pressure does not fluctuate as much. It doesn't take much change in tire pressure to change the handling.
