Ford F350 - Better Diesel Mileage

Hi,

Just bought a 2008 Ford F350 Diesel Dually...and we're wondering if there's anything we can do to improve the fuel economy...seems to drink an awful lot of diesel.

I would imagine it will only get worse once we start towing a 5th Wheel.

Any help appreciated.

Thanks
Barbara

On my F350 [7.3] I installed a cold air intake, as well as 4" banks exhaust. It did help but two different engines. Good luck.

We get 8.5 +- .5 towing, 10/12 around town. There are several chip sets etc. and ways to remove/replace the exhaust cleaning stuff but then your messing with warranty issues and / or running afoul of the laws re: catalytic converters. Now if the warranty has run out and your not worried about being the first to have a LEO crawling under to check the exhaust system, you can spend a few hundred and gain a couple of mpg's. Good luck.

First thing, get a Ford dealer to run an OASIS check on the history of the truck (should have been done before purchase??) and see what Ford has on record for the truck--and get one that covers back to original purchase, not just last 6 months. As to mileage, you can't do much about it if you want to keep what warranty is left intact--if you aren't concerned about warranty, go to this internet Ford diesel forum Diesel Forum - TheDieselStop.com and read all about what you can do to help improve mileage.

Some items about 2008 6.4L diesels: 1) lots of early (before Jan 1 '08) build dates have radiator leak issues; 2) keep an eye on crankcase oil levels to see if there is any gain in volume between oil changes; 3) stick with 5000mile oil changes religiously; 4) drain the water out of the fuel/water separator no less than each oil change, and use only Motorcraft fuel/oil filters.

I haven't had but a few minor issues with my '09 450 that has over 90k on it now.

Good luck,

Joe

I did the same thing and bought a Superchips tuner to program it for heavy tow. I have the 6.0 and get 10-12 mpg towing a 13,700 5th. I also got rid of the EGR and changed the coolant to Cat coolant as not to plug up your oil cooler.

Saw one at the Fort Worth RV show--lots of glitz, but it is still a Forest River product. I believe the one we looked at had a $102000 list and was priced around $72000? Was very nice looking with the full-body paint. They are pretty new to the market, might take a while to have some owner feedback.

Check out the owners forums... http://www.forestriverforums.com/forums/

You didnt buy a Prius. Drinking fuel is what F350's do.

Just curious, Barbara....do you know what the axle ratio is on your truck? Since you bought it used (I gather), it might be worth checking. Any Ford Dealer can decode the certification label info and tell you....OASIS will also. Ford, like other manufacturers, usually offers optional ratios on their HD trucks for different situations where more pulling or hauling power might be necessary. If you have one of these lower axle ratios (higher numerically than standard), there isn't much you can do about it that is cost effective. But it might answer a few questions....just a thought here late at night!
