I have an 2002 F-250 with the PowerStroke diesel and, in addition to being noisy (which I expected), I am disappointed with the gas mileage. I get 10.8 mpg towing a 7000 lb. travel trailer at 55-60 mph. I expected better. Anyone out there with the V-10 or diesel that can share their gas mileage figures?

Comdac: I have the Excursion Diesel and am presently getting 10.6 towing the TT in the signature below at 60/65 mph. My TT weight as loaded is presently 6820 so we are not far apart in loading. Considering the large frontal area of the TT, the fact there are a fair share of hills here in Tennessee, etc. I am very pleaed with my milage....and the noise when towing is a nice quiet hum.

I'm assuming that being a 2002 you don't have a lot of miles on it? Mileage won't increase until the motor breaks in, which is usually at about 10k for the majority.

I'm seeing 13-14mpg pulling 6500lbs with my 2002 with 2k miles on it at the moment

My '00 has 26,000 miles and gets between 11.5 and 13.5 towing the trailer below. My trailer is about 6,000 lbs on average, and up to 6,500 at its heaviest. But the profile is the same. I’ve gone on runs with a friend with the “01 v10 and about the same trailer. He gets 8 to 10 MPG.

My V-10 F250 gets about 9.0-9.5 mpg towing, about 10.5-11 mpg daily driving around town. On long open freeway trips without towing, I have gotten nearly 16 mpg.

I just got back from Texas and got 14-17mpg not pulling the trailer. On my trip to northern Wisc. this past summer I averaged 8-11 mpg depending on my speed.

My previous truck, a 2000 F250 CC V10 with Banks Powerpack consistently got 8-8.5 mpg towing a 7000 lb TT. I typically tow somewhere between 65-70 mph. I didn’t find much difference in mileage with the Banks kit but the added high RPM power was well worth the price of the kit. IMO I really liked the V10 when not towing – it was smooth, low maintenance, sounded and ran great with the Banks kit and was fun to drive. Towing I didn’t like that unless on really flat road with a tail wind it wouldn’t pull my trailer in OD (3.73 gears). Anything more than about 5% grade I had to drop to 2nd gear which was generally 3900-4300 rpm, great power particularly with the Banks kit but noisy at this engine speed.

My current truck is a 2001 F350 SRW CC PSD with Isspro gauges, K&N filter, 4” Dynomax muffler and tailpipe and ATS 70/100 hp flip chip. Towing the same trailer with the cruise set at 70 mph I consistently get 11.5-12 mpg (this is calculated, overhead computer is pretty much useless with the chip). The extra range with the increased MPG of the PSD is nice but increased MPG alone would not sell me on diesel. IMO I love the PSD when towing. On a recent trip I topped about a 3 mile long 6% grade in OD at 70 mph with the cruise control (19 psi boost, 1200 degree EGT pre-turbo) – it almost feels like cheating compared to the V10 truck (same hill with the V10 was 2nd gear and 4000 + RPM rather than 2000 RPM with the PSD). The PSD doesn’t lag every time I hit a small hill, it’s seldom I have to pre-plan a manual downshift, wind just means I run at 12 psi boost in overdrive rather than 8, and my wife actually thinks the PSD is quieter than the V10 while towing.

For me the choice depends on how much I tow. If I seldom towed I’d probably own a V10 and never read a cackle thread again. As it is I’ll probably tow about 7,000 miles this year so I’ll put up with 15 quart oil changes, smell in the garage and potential fuel system modifications.

Hope this helps.

That mileage sounds reasonable, I can get as high as 13mpg towing on flat terrain doing 55. My neighbor has an Excursion with the v-10 and gets 11mpg hwy not towing anything. I find it hard to believe that anyone can get better than 9mpg with an Excursion towing.

So much for the payback formula on a diesel....I get 9 mpg towing with my 8.1.

I know, there is still a longevity advantage, but diesel owners like to cite much better mileage in their calcs.....
