fuel economy - 1999 - 7.3L Power Stroke Diesel

I have just purchased a 1999, F350, 7.3L Power Stroke Diesel. I get 9.2 mpg pulling 20,000 pounds, 12 mpg pulling 6000 pounds and 15.9 mpg just driving around. I'd like to here from someone who has improved thier mileage.

I've heard that adding transmission fluid to the fuel will clean injectors and improve mpg. Any experience with this. How much/often/type/results.

Thanks

When pulling my concrete form trailers on the hiway at 2000 rpm's i get 14.5, the weigh in at 6500 to 8000 lb's. When I am running empty I get 17.5, truck with tools and me weigh 8500 lb's. Best I have gotten is 18.64 traveling through oregon without the cruise set and going the posted speed which was mostly 55-60.
I run Diesel kleen to help with the ulsd fuel and have modest results with added milage.
You don't mention if you have a hand shaker or auto. Manuals tend to get higher fuel milage than auto's

i agree with using diesel kleen i was getting about 14 after they switched fuel before i started to use the diesel kleen now i'm probably close to were i was switch was 18 just driving. i don't pull a trailer long enough to burn a full tank to get a milage reading

Stay away from the trans fluid in the fuel deal, TOO much additives that were not meant to be burned..

Use a fuel additive that was meant to be burnt.

We used to use the AT in the old style diesels, about one quart per 250 gallon fill up.
I've been told more than once that mixing in AT in these modern diesels will ruin the injectors.
Stick to DK or one of the other quality additives.

My manual for a 2001 shows you have a 38 gallon tank with a long box regardless of the cab size. I bet your 00 is the same. Surely you have pumped well above 30 gallons in there being a dead giveaway.

I am assuming you have a dulley, 410 gears, I had one, thats about as good as I got? Remember, 410 gears are for pulling, suck it up!! Just kidding If you keep your RPMs below 2 k you will yeald your best milage, but get there slower!

Yeah your MPG actually sound pretty good I do agree with trying to keep it below 2k it seems that there is a huge differece in fuel usage between 1900 and 2100
