    Gas Mileage comparison, '99 vs '03 Explorer XLT

    I recently traded my '99 Explorer XLT for a '03. Both have 4.0L V6, 2
    wheel drive and 3.55 axle.

    The '99 is rated 16 city, 20 highway, the '03 is rated 15 city, 21
    highway.
    My driving is approximately 35% city, 65% highway.

    I record every gallon used, and enter it into a spreadsheet which
    calculates tank mileage, 10K mile average, and overall average. The
    first thing you notice is a tendency for the tank-to-tank mileage to
    go up and down about 1-3 mpg. I feel that any measurement of just a
    tank or two probably contains significant errors. Here are the totals
    from my two cars:

    '99 Explorer 57362 miles, 3036 gallons 18.89 mpg.
    '03 Explorer 4063 miles, 234 gallons 17.36 mpg

    Bottom line, I'm surprised the new Explorer is getting lower mileage.

    Did your '99 have the SOHC 4.0L V-6 or the
    pushrod 4.0L V-6? My '91 Explorer (pushrod
    4.0L V-6) got about 1.5 to 2.0 MPG than my
    '02 Explorer with SOHC 4.0L V-6. Both had
    the factory tow package with 3.73 axle and
    were 2 wheel drive. Also, the '91 weighed
    about 200 lbs. less than the '02.

    The difference is not THAT great. My guess is that as the new ride
    breaks-in, mileage will improve that 1MPG difference. True, your old vehicle
    included the break-in period, but the total sampling period of almost 60,000
    miles gave a truer picture than just the first 5000. Give it time and, hey,
    it's an Explorer. 17MPG...18MPG...it's not going to compete with PRIUS for
    mileage champ.

    Your '03 with 4000 miles is not broke in yet. See what it does between 4000
    and 6000 miles in the next couple of months. Tire pressure? I run 35rear and
    32 front.

    Hey Chief, what tire pressures are you running? And do you have full-time
    4WD? I run 31 pounds all around, and my gas mileage is a bit lower -- 14-15
    in town. Mine's a '97 XLT V8 with 94K miles and full-time 4WD.

    Right, and my 4 liter '92 got better mileage than my 4 liter '99.
    Obviously, the push is to increase horsepower, not fuel mileage.
    Having said that, gas mileage tends to be low for the first few
    thousand miles.
