Ok guys i DECIDED TO PUT A NEW TWIST ON THE SITUATION. Instead off a thread about poor mileage an what mileage you get on these ttrucks. This is a thread about people getting good mileage. Tell me the truck you,the cab configuration. rear wheel ratio. Your ttype off driving. Highway or city. Lets keep the responses to 15MPG or better. Maybe a tallorder but will see. If you get less then 15 MPG dont respond if you get 15 plus MPG tell me about it.

 

Hello everyone

2008 F350 6.4L Manual Tranny Long box supercab w/ canopy. Only got 2000KMs on my truck....so far I have made 2 highway trips and recorded mileage and got 18mpg on one and 17 on the other....no wind and mostly flat roads travelling about 120Kph on cruise.

 

I'm getting 15+

:-)

 

Snooky, are those us or imperial gallons, or doing a conversion from metric to "standard"? I'm wondering how you're measuring since you mention metric/kilometers.

 

2008 F250 FX4 SC 3.73 6 speed manual. 15.2 city 19.1 highway. 2800 miles on the meter.

 

2008 F-350 Crew Cab Dually, 4x4, Manual tranny, 3.73's.

Just got back from a 250 mile trip and averaged 18.5 mpg @ 65 mph with a 700 lb ATV in the back and another 500+ lbs of gear.

I average between 17-20 mpg empty on the highway, and 15-16 city.

 

jeez how the crap are you getting that good of mileage. My dad has a 1-ton dually and hes lucky to see 12 and thats with major babying.

 

13,000 Miles. 3.73 axle. 6 speed manual. Truck in signature. Avg towing 10,000 lbs: 11mpg, avg empty in town 15-16 mpg, avg empty highway 18-20 mpg. (Once got 23 mpg on a 400 mile trip following a friend at 60-65 mph)

 

Ive got 6600 pure NYC traffic commuting miles. My shortbed club cab 3.73 auto just pushed up to 12.7 and because of the low expections I am actually happy.I have had very similar mileage with lesser trucks. My only issue is at least a daily regeneration but that has to be expected. Peter

 

Manual tranny, keeping the boost below 10 psi, and 3.73 gears. That's all it takes to get good mileage in a big truck. That's even running a SCT 80 hp tune all the time.

 

. Daily regen is killing me too most of my fuel is used in regen-daily. Ford says that's normal-they don't know How did once in a while get to daily?

 

Off topic, but if you drive a lot of city miles, my SD stays in regen mode I can count on one hand the times it ran at full power,hard accellreating and snappy. The rest of the time I feel like I'm driving a six cyl.in a 8K lb truck.

 

Normal highway, tnpk, interstate driving at 63/65 mpg we get 15/18+ on a regular basis. City driving or daily driving is to varied to mean anything as we all drive in different conditions. Daily driving today we did 15 tomorrow maybe 12 or less if we get into heaver traffic or get a regen. Note that at 70MPG and over the MPG plunges. Considering this truck set up for towing a 5th wheel Rv , Full fuel and wife and myself aboard weighs in at over 9100K.we feel the mpg on these new motors is acceptable.

 

Ace!,
actually, that is converted in standard....imperial would be about 15.1 or so being the same as 18mpg, if i am calculating correctly.....
I still believe that is great mileage considering that was for an average speed of 75mph...maybe?

I agree with the keeping <10psi boost w/ the 6spd.....major benefit for mileage...

 

I have a reg cab long box,6 speed manual, 3.73 rear gears. 16.9 I drive both city and highway. Some things I've noticed: I keep the boost below 10 when I can. I shift at 2000 rpm when ever possible,I have been using the Ford anti-gel-performnance additive since the first tank. I also reset the mpg meter whenever it starts to stay at the same number for a couple of days in a row or starts to drop for no reason. I may be way off base here, But I am also starting to think that the ULSD may be like the oxyagenated vs.non oxyagenated gas. You use more oxyagenated then non oxyagenated gas. But again thats just a feeling on my part.
