Re: for the ford guys
a major tune up does not happen every 5000 miles but an oil change does...
v-10 = 5 or 6 quarts and a filter
powerstroke t444e = 15 quarts and a filter
a tune up on the other hand.... well both need fuel and air filters, belts, and hoses at about the same time.... coolant flush again about the same time but the 'stroke will use nearly double the coolant.... Trans filter and fluid.... again same time but I just did my 99.5 stroke last week.... 22 quarts (has an aftermarket pan) and wix filter $100
The gas engine needs plugs and wires every 100,000 for what? $50? the stroke needs new injectors at about 200,000 or so for $1000-$5000 depending on if they are reman's, new, done yourself or done by a ford stealership.
A good 4r100 transmission for the 'stroke is $3500-$5000 plus installation
Dad's single rear wheel 2002 v-10 4x4 gets 12-14 mpg empty and my 1999.5 crewcab dually 4x4 gets 12-15 empty, The diesel had a fair amount more power when stock but now I have put about $3500 worth of goodies on it and I can pull a 6% grade grossing 26,000 lbs at 75 mph although I do have to watch my egt's.... If I do lose enough speed to drop out of overdrive they like to climb at the higher rpm's
One thing to consider that is generally lost on the folks who buy new with a warranty.... The diesels require tools and diagnostics that most mechanics don't have and quite often even the dealer's mechanics just guess and throw very expensive parts at them...
There is no doubt that the diesel is a dream to tow with and I love mine (usually) but if you don't need it I would suggest staying with the cheap and easy..... gas
I suggest that you check out powerstrokenation dot com for the level of expense and trouble these older trucks can be so you can make a more informed decision.... I'm gottagofast on there btw
