Finally got to sit down and figure the numbers for 2010 on the truck.

60,152 miles driven

Gas $15,524.30
Gal 5,988.05
25 cents a mile
10.04 average MPG (I wish I would of recorded the towing miles better and couldn't tell, will keep better record this year.)
$2.59 average a gallon

$42.79 - 1 oil change on the road traveling.
$36.70 - 10 Oil filters @ 3.67 each.
$220.71 - 70 Qts (5w20 Motorcraft $2.62 average.)
$40.37 - 3 fuel filters. (15.99/9.39/14.99)
$15.99 - 1 Air filter.
$110.82 - 10 Spark plugs. (Motorcraft)

Total $430.68

$430.68 + $15,524.30(gas)=$15.954.98
$15,954.98 divided by 60,152(miles)=26 cents per mile.

All maintenance on truck was done by me except for the Trans. flush and the 1 oil change.

Other expense not figured in the amount above are list below, figured it would be a wash seeing that the gas/psd would both have the same to do.

$192.11 Trans. flush
$85.98 Front/rear brake pads
$9.94 wipers
$11.99 windshield repair kit
$1,024.44 6 Tires

$??? Who knows how many cold ones while working on the truck.

Maybe this will help someone Figuring the cost for them to run their truck and make an educated decision on which platform(gas/dsl) works better for them.
