Mpg-help
I Didn't Buy My Excursion For The Gas Mileage, After All, This Is My Second Excursion With A V10 So I Know The Mileage Isn't Great From The First One. However, My Wife Was With Me When I Filled Up The Other Day And It Cost Me $80 For Reg Gas. I Have Added A K&n Fipk, Gibson Exhaust And I Am Running The Tires At 70psi. Whats Next To Save A Few Mpg.
Anyone Know If They Are Running That Winter Additive In The Gas, Mileage Appeared To Drop 2-3mpg In The Last Two Months, Was Getting About 15.4 In October And Now I'm Running About 11 To 12.5. I Had The Same Problem With My First Ex In The Past.

Seriously though, driving technique will make more difference than any accesory! One of the truck mags did a test with several trucks, with various loads and with a trailer and it was amazing the differences they documented. Bottom line: accelerate SLOWLY and coast, not brake. This requires paying close attention to how you drive (i.e. don't stomp on the accelerator and anticipating red lights so you can coast early and maybe you get lucky and it changes before you get there) and watching the tach and vacum (if you have it).

Mostly in the throttle!
Mine will only get 14-15 around town if I don't drive careful! As high as 19 in town driving deliberately...as high as 24 cruising almost constant 65mph for 300 miles! I get between 12-14 towing a 34 ft/8,000 lb trailer.
Stock, and sometimes hypertech level 1 (safe-tow) program. no other mods yet.
Its almost entirely driving styles...I'm probably the guy switch lanes to pass at the red light!

no additive, I've tried several and will probably try some more but I could only get 1-2 mpg difference (less than the variation I have gotten from tank to tank because of diesel quality, seasonal blends, etc.)
While I still think much of it is driving style, there is quite a difference from truck to truck from what I've seen...the same drivers switching trucks on a long trip and getting ~5mpg difference in the other. I've seen several people here getting in the 20's hwy & empty. There was a thread in the archives comparing 7.3 mileage...seemed like there was two camps, about 50/50: getting high teens-low twenties and getting mid-low teens
6.0 was supposed to get better mileage...I had several (at least 2) friends that traded high mile 7.3 in, were so disapointed they went back and got a used 7.3 only to find that there original 7.3 was a good mileage truck and the "new" 7.3 was greedy. Most went to a Cummins after that.

I drove my X with 7.3 PSD to Kentucky the other day. Got 18.5 mpg on the way down and 20.2 on the way back (400 miles round trip). I believe the difference was fuel quality. I bought Speedway fuel before heading out and got truck stop (Love's) fuel on the way back.
I drive an F-250 v10 for work and have driven about 105,000 miles in 2 different trucks. The old one had 80,000 miles when I got it, it got 11-12 mpg everywhere. Had a tune-up done, which just consists of new plugs, and got 12-14. This was fully loaded all the time with a steel cap. I believe it weighed in at close to 8000 lbs. The second truck is getting 11 mpg and I will probably get plugs put in it soon since it has 118,000 on it now. It is also not fully loaded like the last truck, so hopefully I will see a larger improvement.
One other thing to note, it does not take a lot of idling to affect fuel mileage. I notice if there was anytime I idled the engine for 15 minutes or so, it could decrease the mileage on that tank by 1-2 mpg. That is my observation anyway, maybe someone else has had the same experience.

I see the same thing Scott. I idle my truck a lot for various reasons. Hard to get an accurate, real-world MPG figure when the truck has been idling for an unknown amount of time each tank.
I'm sure I can dig up the info on fuel consumption at idle somehwere and plug that into my "equation" but MPG doesn't really affect me. Guess I've got past it with this being my second V10 also. Until it drops in the single digits I'll continue to feed it when it asks for it....no questions asked.

What is needed is cost per gallon & miles driven.

You really cannot do much more than that. use high quality oils in it and keep it properly tuned. Anything else added (ie. Gear Vendor O/U) will never get you any payback.
Some will argue that that FIPK is gonna kill your engine in the long run so you may want to reconsider it. Paper flows equally as well within the operating RPMs and filter much better.

I've noticed about .5-1 mpg/per tank loss for the last few tanks - I attribute it, mostly, to idle time (morning warm up) and cold weather. But I've also found that I have a small leak in my right front tire - when it drops below 40 psi, I see a noticable drop in mpg - so now everytime I fill up, I check the psi in all tires.
I'm also due for an oil change, so that could be eating a little mpg's as well.

I just finished a trip to FL and back. About 2000 mi of 70-75 mph interstate (including 2 half-hour traffic jams), and approximately 200 miles of city-type driving. I drive very conservatively-slow starts and gradual stops with my 2000 7.3 PSD. The mpg for the whole trip was 20.2.
