I drive a 2000 Chevy S-10 pu, 2.2, auto, air. Great little truck; what makes it great is the gas mileage. My routine on the road pretty much drive the POSTED speed, see the signal change go to neutral/barely touching the brake enough to slow down to a stop. Now if i know the signal is a LONG wait, i'll stay in neutral same time foot on the brake full pressure with parking brake engaged(hopefully to not allow vehicle to move if rear ending occures). Now i do use my a/c, but spareingly; i have dark tint on glass so a/c at low setting does the job. Great little truck in every sense.

Now the best for last-ALL PU OWNERS DROP THAT TAILGATE! It's been shown that air flow over a pu with tail gate up like driving a brick on the road, bad airflow engine has to work harder to push the vehicle forward. By dropping the tailgate, that flow moves nicely around, up & over the body. Experiment it yourself; 1 tank of gas with tailgate closed; 1 tank of gas with tailgate open. BIG difference. Now you may want to invest in a bed cover(kind you lock, functions like a hood)if you need to keep items in rear area. Now, if the idea of burning 2 tanks of gas gives you vapor lock, experiment Hollywood style; 1) find a big enough room/building you can drive you vehicle in/out safely, 2) the use of a large fan(the fan must be able to put out at least 50-60 mph wind to simulate travel), 3) a smoke bomb/grenade(i have a white truck so i used white smoke). I wished i still had the video of the 'wind tunnel' testing. You would be shocked to see the diff when tail gate in up/down positions.
