Hi all,

I currently own a 2000 V-10, which I love. I tow an 8,000 pound trailer about 20 weekends per year. I'm trying to figure out what real mileage people are getting with their Excursions. I'm pondering getting an '03 6.0l PSD and have heard various stories about what I can expect. For the V-10, 7.3l and 6.0l PSDs I'd love to hear from other what they are getting for highway, city and towing mileage.

Mine are: hwy - 13/14, city - 10, towing - 7.5/8.5

Thanks all,

steve

I have never been below 11.5 on the ford MPG indicator,

I have been up to 20.5 on the highway, and to more acurately reply to your question I have gotten 730 miles out of a tank of diesel (44 Gallon tank) =16.5 MPG average on that tank.

I have heard good and bad reviews on the 6.0L Diesel from Ford. My recommendations would lean towards the 7.3 liter PSD, they are proven and have been around for years.

Don't step on that gas pedal so hard! I routinely get 12MPG city (calculated, not indicated), 15.5 to 16 highway, and 11.5 towing 5200 pounds ... 2001 V10 4x4. The following is a copy of something I posted on another Excursion site:


The diesels may get better MPG on a one-to-one comparison, but when you factor in the initial extra cost for that diesel engine (around $4K) and the typically higher cost per gallon of diesel fuel, then it takes a very long time ... probably around 200K miles ... for the costs to equal out. My gasoline engines have had no problem going 200K miles, and by that time, I'm tired of the vehicle and ready for a new one.

Just did the calculations. Assuming a diesel gets 18 MPG and the V10 gets 12 MPG (actually, gets more on the hwy), and diesel fuel is $1.50/gal. and gasoline is $1.25/gal. (usually about $0.25 difference between the two in eastern Virginia), the diesel uses $83.33 worth of fuel every 1,000 miles while the V10 uses $104.16 worth of gasoline every 1,000 miles. Thus, it will take 192,000 miles before the diesel sees ANY savings over the gasoline V10 when the initial $4K investment is included. And this comparison doesn't take into account all the remote areas where it's nearly impossible to find diesel fuel ... an intangible. On the other hand, diesels have some intangible benefits of typically being more reliable. My vote still goes to gasoline engines until I get a truck so big that gasoline fuel is no longer an option. They’re more economical, quieter and don’t stink as bad.

And like I said, I'm ready for a newer vehicle by that time.

So, all in all, I think the V10 is a shade more economical. However, diesel fuel prices in your area may tip the scales the other way ... but making up for that initial cost will take thousands of miles.

Just to add to LandYot, doesn't a diesel use more oil?? Thus making oil changes more expensive?? I don't know this first hand, my father-in-law has a dodge diesel and I seem to remember him saying it takes some unbelievable amount of oil. I know it isn't much, but it all adds up. My MPG are almost exactly what you are getting Steve, and I know my brother with his F-250 7.3 doesn't get whole lot better. Overall, I tend to agree with Landyot.

I like my V10. I get 11 mpg or so around town and near 13 highway. Still, I have to admit I have diesel envy. Maybe it's just the sound. I don't know. But I still find myself wishing I had one. Except for when I order fast food. I don't have to kill the engine.

I am looking at getting a used Exc. and am not sure what engine to get or am towards. It will be for mostly city driving. I don't plan on towing anything either at the moment. I know that diesel fuel costs more but is the gas milage better compared to the gas? Can someone add to the mentioning of the oil changes cost more or more frequent on the diesel? is it beacuse of the turbocharger?

If I recall correctly, and someone correct me if I'm wrong, the diesel has about 15 quarts of oil with a filter change. It's a very big sump.

If you go with an oil analysis program and a bypass filter you can avoid changing the oil every 3000 and save some money. Check out http://www.bobistheoilguy.com for anything you need to know about oil. Primarily look for posts about bypass filters and extended drain intervals.

I'm going on 13,000 miles so far with my current oil in a V-10. So far so good!

Does this mean you haven't changed the oil in this long??

Yup!!!

I run Amsoil full synthetic oil, an aftermarket bypass filter and an Amsoil full flow filter. The full flow gets changed every 12,500 and is comparable to most regular filters except this one has a bit more capacity and slightly better filtering media. The bypass filter is changed every 30,000 miles or as needed prior to this if an analysis should indicate that it's not doing it's job. It filters down to 1 micron. I did an analysis on the oil at 5000 and 10,000. When I change the full flow filter I'll do another. This will tell me how well the oil does at each interval and should tell me when to actually change it. In theory, as long as I keep topping it off when necessary I shouldn't ever have to change it.

The bypass filter keeps all of the contaminants out and topping it off keeps the additives in line as well. I don't think I'd keep it in there too long though simply because I feel a fresh fill of oil every now and then is a good thing. However, there are documented cases of small engine trucks (not the big rigs or bulldozers etc) that have run almost 200,000 without changing oil and the engines have shown virtually no wear. The big boys run lots more than that...some as high as 750,000 miles. Freight trains....some have 250 GALLON sumps. They have even better filter systems in those babies and pretty much, from what I have read, they NEVER change the oil! They top em off regularly and change the filters but that's it. Then again, some of em burn about 20 gallons every week so topping em off refreshes the mix quite a bit.

So, it is possible. The initial investment in the setup is a bit expensive and somewhat of a pain in the butt. However, if longevity is what you're after it's the best way.

I get anywhere from 14-15 around town and 17-19 solo on the highway, depending on speed and wind.
Towing, I get between 10.3-11.8, again depending on speed and winds.

Bought the diesel for towing ability (torque) and longevity. The better mileage is a nice benefit that mainly translates into more range between fill-ups, but the real reason I bought a heavier duty rig was that I was tired of burning up half-ton Suburbans towing our travel trailer. If I'm nice to it, this one should last until I am tired of it. That could be awhile because I tend to keep my cars for a LONG time. I like the 7.3 engine. Haven't tried the 6.0 liter yet, but even the service manager at my dealership admits they are having 'teething problems' with the new engine. I figure a mid-production year '04 would be about perfect if one wanted a 6.0 liter before they stop making the X.

At about 11k miles so far, and I love my X. Too bad Ford is so brain-dead on this vehicle. They never really understood the market for this vehicle. A true second-gen X would be incredible, but alas....
