I'am going to be getting a new truck this week I was think about a diesel I was wondering what kind of mileage to expect I know its a big truck so its not going to be great

 

It really can vary depending on what kind of truck, big tires/lifts, how you drive and where you live.

I had a 2003 and now a 2006 F350 CC SRW and get around 13 in town and 17-18 on the freeway at 70-75mph. My trucks are stock.

Cold Weather and winter grade fuel minus 1-2 mpg
Big tires or lifts Minus 1-2 mpg
Very hilly country minus 1-2 mpg

You will see post from Flat landers who claim 20+
It really depends on lots of factors.

Personally, I don't think you will not save enough in fuel to justify the extra cost of a Diesel or the added cost of todays diesel fuel. If you buy a diesel, it's because you need the extra power to tow or haul. Not because it will save you money.

I may get 14mpg towing my horse trailer down the hiway with my diesel, where as a V-10 gasser might get 11mpg. At todays fuel prices, the diesel MAY save me 2 cents a mile in fuel, But at $5000 extra for the engine, 15 quarts of oil every oil change, two fuel filters etc. In the long run you are not saving.

 

Gear ratio? Automatic or standard? 2wheel drive? 4wheel drive? RC, EC, or CC? All of that can have some impact on your MPG.

I have 06 F350 CC Fx4 w/6.0 and 3.73 stock with exception of a leveling kit and my driving is about 50/50 between city stop-go and toll road. I am not one of these take off like a flash and then slam on the brakes, gun it and start over. I do run with traffic which at times on the toll roads can be in excess of 70. Have almost 5k miles on it and best I have ever gotten was 14.1 and worst is 12.9.
You are going to have people tell you they get fantastic MPG and some of us just don't. Can't tell you why. I personally like the Superduty styling and this is my second one. First one (2000) had 7.3 and it was a great truck also.

I agree with Painted Horse, don't think there is fuel cost savings justification these days since diesel is higher than regular gas. Cost of oil changes is higher, filters and such are all higher for diesel. I got a great trade in for my 2000 compared to what I think I would have gotten for a gasser with the same miles on it. I drive a diesel because I tend to put lots of miles on a truck and because when I do pull a trailer, they do a great job.

 

automatic trans 3.73 gear my Farther is a retiree so with the discount it's about 4300 the truck is always gona be worth at least 4300 more than with a gas motor probaly more like 5k to 6k more theres not many trucks around here with gas motors in stock the rebate on a diesel is 4000 for retiree's now but i have to buy thiis week
I live in Michigan its flat I do drive fast thought I have a 250 with a 5.4 now it gets beteen 10 and 12 city/hwy and about 7.5 going to the UP snowmobiling

250 4x4 supercab with 6.0 thats what I'm thinking about

 

I don't think you will get any worse fuel economy than you do now and I think you will have a much nicer ride, JMHO.

 

Not trying to start another gas vs diesel debate, but I disagree.
Here in southern Wisconsin, diesel only costs about .03 a gallon more than gas right now, and at 18 mpg for the diesel vs 14 mpg for the gasser, in the long run you are going to save a considerable amount of money, not to mention the fact that the diesel will be worth at least $2000 more at trade in time.

 

wow! you have some very good diesel prices. diesel here is 2.75-3.05 in some spots gas is 2.61 for 87.

 

Wow Octane, You've got expensive gas. I pulled up the nationwide fuel chart and I see that gas is 2.549 vs diesel at 2.569 in WI. Thats not the case in the rest of the country. Regular gas is 2.219 and diesel is 2.569 around here. Most places are seeing a 25-30 cent a gallon premium for diesel now. And while I do get 18mpg when I get on the Interstate and set the cruise at 70mph, I don't get much above 13 when I'm driving in town, which is the same as most of my gasser friends get. So it really depends on the mix of each persons driving.

 

I just filled up yesterday for the first time since getting the truck new. It is a 2wd F250 6.0 SC lwb. Diesel was 2.379 and Regular was 2.419. That is unusual though since diesel is usually the same price as either mid grade or premium grade gase around here. I still see some places where diesel is higher than premium. I got 16.7 mpg calculated and the info center registered 17.0. That was mixed around town and highway. I was babying it and staying under 75 mph. I reset the mpg with each tank. One thing I noticed that was interesting is that it doesn't seem to get as good gas mileage when the engine is cold. I would think that someone that has short trips would get less gas mileage than someone with longer trips. The way you drive it will have a big impact on the mpg too.

Yeah, diesel and gas cost about the same right now. I filled up on Sunday and gas was $2.59 a gallon, whereas diesel was $2.61 a gallon.
If diesel were .30 a gallon more, then yes, a diesel would not save you money but with the prices being close like they are now, a diesel is worth every penny you have to pay to get it.

 

I don't think that gas mileage alone is worth getting a diesel. If you use an average of $2.50 per gallon for both gas and diesel. Assuming they cost the same (which 99% of the time they do not, gas being cheaper). And for arguments sake since there are wild claims all over the place, lets say the diesel averages 15 mpg and the gas 12 mpg. You would have to drive 119,000 miles to make up a $5,000 difference in the cost of the diesel.


Now if we figure the gas costs that Painted Horse pulled up $2.219 for gas and $2.569 for diesel, and using the same MPG figures you would have to drive 367,647 miles to make up the difference. Of course this doesn't take into account maintenance. Also I believe the diesel was more than a $5,000 option.

Now if the diesel got 20 mpg and the gasser 10 mpg you would only have to drive 53,500 miles. Now that would be worth it for the normal driver/occasional puller. But it is also a pipe dream as the diesel will not do that good and I have/had 2 V-10's and they get 12-13 minimum.

BTW I currently have the V-10 had a diesel, loved them both, this is not meant to knock one or the other.

 

DEF get a diesel
I recomend a 1999=2003 those have the 7.3 which IMO are more reliable
I have the 3.73 gear ratio and get about 15 MPG D/D and 18+ highway

Good luck!!!

 

My neibor is a former Ford technician and according to him the 7.3L is no better than the 6.0L. According to him, they both have their issues and the 6.0L is just as good as the 7.3L was.
Just a little FYI.

 

I just bought a V10 as I can't see any benefit of a diesel. I don't tow that much & the V10 will satisfy all my needs. However, if you need or want a diesel, I would wait for the new 6.4 to come out in Jan & see how it performs, rather than buying a 6.0 that has another 9 months of life before becoming obsolete.
