Mileage expectation on tuned 7.3??

I am going to see a 2000 7.3 DRW tomorrow with 250k miles. My purpose for this truck is highway towing - mainly to tow a car hauler with cars I've bought at out of state auctions. I've had several 6.0s in the past and experienced decent mileage - 15-18 mpg unloaded and 10 mpg with a loaded 3 car hauler. What kind of mileage should I expect from a 7.3 motor with "tuning" software installed? Thanks!

Hard so give you a real number on either of those... Way to many variables. I will tell you if the motor is taken care of and isn't ran with excessive EGTs it will last for a very long time! I worked with a guy that had almost 600k on his 96 F350 and he tows cattle/farm cr@p every weekend. Maintenance is an important factor, especially them fuel filters.

As I understand it you should see similar MPG out of the 7.3... possibly even a little better loaded. if all stock.






If you want to do a little extra to the truck.

Pick up a good tuner, I recommend DP, and you'll do alright. I've also seen a test where putting all synthetic fluids in the drive train actually made a noticeable MPG difference.

Let the motor breath, 6637 are filter and turbo back exhaust will also give you a bit of a mpg boost. Single shot injectors are supposed to be good for 1-2 mpg as well.

Thanks. I saw the truck this afternoon. Very smooth engine. No oil or even film on the bottom of engine and trans. Interior was rougher than I wanted. Only mechanical concern was the air filter housing only had one clip. The air filter was filthy and looked horrible when I lifted the side of the box and peeked in. I will continue to look and take my time.

Take a look at the turbo right away... pull the intake off and look... that broken air box is a big cause of a dusted turbo you need to check the fins for signs of dirt ingestion.

Thanks. That is what concerned me about the air filter box - turbo concerns. With the interior also needing seats, I passed. If the previous owner did not maintain the air filter, I can only imagine how neglected the fuel filter might be.

With my PHP tunes using the 65hp tow tune I'm getting 11.2mpg towing a Keystone Laredo that weigh's in at just over 8,000lbs. I held a cruising speed around 70mph, a 7.3L stock will not have the power as the 6.0L so don't be looking for a 7.3L too blow down the highway unless you tune it.
