Toyota Tacoma upgrades

Back to the original question. The one thing that did improve mileage for me in a truck was switching to synthetics for both the engine/diffs and transfer case. My old Dakota that I bought new went from 19 to 21 when I did this in 93.

Anything you can do to get the brick out of the air will help as well. I have thought about switching mine to synthetics for the transfer case and diffs.

I drive an import as well. Built in Mexico and sold in Canada. Then imported to the US a couple of years later. I get 18 in town and 20 driving 60mph with a light load in the bed (1000lbs) I get 14-15 pulling the brick that is our 7000lb camper. 98 Dodge 12V/5 speed with 3.54 gears. I have heard some of the early (98-01) 24V ones can get 23-24 but never seen it first hand.

And if I drive at 65-70 the mileage go's in the flusher. I also have a little taller tire making the effective ratio closer to 3.35-3.40. Got to keep it under 2000rpm.

+1 the cummins reaches max torque at about 1600 RPM, anything over that you are just adding fuel to a fire that is already lit. RPMs are not your friend when it comes to a real diesel engine.

the torque curve on my 05 hits max at 1600 and does not drop off at all until 3200. it cruses with a load at 70 mph just under 2000 rpm. this seems to be its sweet spot for MPG. and quite honestly with my 35 footer and either the boat or trail rig behind it the 70 MPH is plenty fast.

OP: Did you consider chipping the computer? Often these kits come with a small display that lets you select from performance/mileage settings, and display additional system information.

I mentioned it in an earlier post
