Yes, nitrogen + oxygen + high temperature. Any air breathing engine produces NOx.

With US refineries running at 95% capacity, if a refinery goes down over the summer, we might get $10/gal in CA...so I try to top up the fuel tanks. E85 is usually uneconomical to run in CA but right now it's cheaper per BTU than gasoline plus it's an octane booster so I am adding a bit to each tank if I drive by the Propel Fuels pump.
