No I didn't read 20 pages, but would like to add that Hypermiling endeavors to keep the rpm low or coast with the engine off. This massively reduces throughput of air. A 4-cycle ICE ingests its nominal discplacement every 2 revolutions at cruising speed. If you take your rpms at 2500 rpm cruising, your ICE ingests its displacement 1,250 times per minute.

My '00 Corolla uses about 16,000 gallons of air for every 1 gallon of fuel. 30 miles round trip to work, 30 mins of driving round trip, average rpm 2200. My truck uses 36,000 gallons of air for the same trip (1,500 rpm avg).

I breathe about 100 gallons of air for the same trip, 30 mins.

Thank you to everyone who does engine off coasting and engine off at lights!

Darrell (OP), you should congratulate yourself for not heating the atmosphere as much as the average person
