Should we offer the compressed air oil swap to him?
The air gets expensive, but your car is so much lighter without all the nasty oil; after the first 100 miles on air, you should see water come out of your tailpipe.
This is some of the purist spring water around and works great in your radiator/unless your running compressed air coolant as well, but that's hard to do and involves HVAC training.

 

If you use nitrogen instead of normal air it makes the car lighter too

 

Weak...nitrogen is inert so you won't get that bang you need for performance. You have to go with pure oxygen or hydrogen.

 

+1 FoR HYDROGEN!!!!

 

But seriously, please stop working on your car.
