I'm a bit of a leadfoot when the green light comes on but, no, the driving wasn't much different from normal. Nor was the mileage. That engine in that truck just sucks gas. It always has. Not quite 10 mpg, usually 12 or 13 but, yeah, it's a gas hog.Was that a 1/4 mile at a time?
How big a factor is this, really? For example, my tires are supposed to be at 35psi. Suppose I aired them down to 20psi. How much mileage change should I expect?Tire air pressure changes with ambient temperature. The rolling resistance would vary.

That had to do with density altitude. Different temperatures In combination with altitude creates denser air. Denser air equals more power. Simple calc, ask any pilot.i had a 96 Chevy 2500 that got and extra 3 mpg and much better performance when the temp was between 40 and 50 degrees, as long as the humidity was low. It had to do with the tuning of the throttle body.
What's not to like. Drive over the edge and you get 32.174 ft/sec [squared].Loved racing in mineshaft air (negative density altitude
Every half ton pickup I've had has gotten in the ballpark of 16mpg (unladen) regardless of engine size. That's just the amount of fuel needed to drive a vehicle of that shape and size. Might as well go for the bigger engine for when you need it.Undersized engine?
Different temperatures will have an effect at the same altitude. Colder air is more dense regardless of altitude. Humidity and barometric pressure also enter the equation.That had to do with density altitude. Different temperatures In combination with altitude creates denser air. Denser air equals more power.

Head wind, and side wind all have a heavy effect on pickups. Try running into the wind with a 4X8 sheet of plywood. A side wind messes with your rear vortex, causing additional drag. Add this to the mechanical and frictional rolling resistance. Most passenger cars are shaped like a lump to reduce the effect.Different temperatures will have an effect at the same altitude.
