MPG Question?
I am just curious to see if my expy is getting the average MPG that everyone elses gets.
I have a '99 XLT 4x4 5.4 w/ 3.73 rear, with K&N filter in stock air box. I use 5w30 Mobil 1.
The past 3 months I have been driving about 90% city and 10% highway. I have been averaging around 12.2MPG, is this average?
My last tank since it turned colder here in western NY I have droped to 11.65. I am just curious to see if others with the same setup get the same gas mileage.
Thanks
Mark

What's your tire pressures set at? If they are too low that will cause a decrease in mpg. Maybe try resetting your computer by disconnecting either the negative or positive battery cable for approx 15 minutes. This will reset the computer and re-learn your driving habits.
Also, how many miles do you have on your expy? It could be time for a tune-up??
Just some suggestions, good luck.

My wife's 2002 EB 4x4 5.4 w/ 3.73 rear, with Fram stock filter in stock air box and Motorcraft 5W20 gets 12.2 also. She drives 2 miles highway @ 60 and 4 miles stop & go city to work.
If I reset it and drive it to work which is 20 miles of Interstate @ 70 and 20 miles of city expressway @60, I average 18-19 MPG.
12 city / 18 highway

I bought the truck with 73,000 miles and I have been tracking the mileage ever since february when I bought it.
I am not really worried about the mileage I am just curious as to what everyone else gets with their expy's.
Thanks

10.5-11.0 city
14.5-15.0 highway
You think these #'s are bad, my '68 gets about 6 mpg. But then again, I've always got my foot to the floor on it and I've only driven it around 1,000 miles in the 3 years since I restored it.

I have a similar set up: 1999 XLT 4x4 5.4 w/ 3.55 rear, with K&N filter in stock air box. I also use 5w30 Mobil 1. 61K miles.
Drive mostly country back roads. Avg 15mpg. I can get over 17 running 70 on the highway. Around town it drops to 12.

My Expy has the same specs you mentioned for yours, just a little older with 116K miles. 12 mpg is what I get consistentlly while around town. 16 - 17 mpg on the road at legal speed limit or 70 or 75. Next week I'll put on 4K miles of interstate driving with new upstream 02 sensors. I'll let you know if the mileage changes.
