I filled up my Mustang this morning and set a new commuting record of 31.89 MPG. That's only .07 MPG less than my best ever road trip MPG of 31.96. I'll hit 32 one of these days...
This was accomplished with:
Tires @ 32 PSI, filled with a natural 78% Nitrogen blend (from my air compressor)
No P&G
No EOC
No DWL
No drafting
No gadgets
No gimmicks
No "snake oil" additives
