I feel like maybe your are doubting my mileage calculations. I am not trying to fudge numbers or act like I am getting crazy good mpg. This picture was taken back in September I am 200 miles in to a tank of fuel witch would be approximately 3 days worth of driving to and from work. This has been typical for me and my driving habits. As I stated before most of my driving is back roads with rolling hills at 50-55 mph. This seams to be a sweat spot for good fuel economy. In my opinion. My last truck was a Chevy 2500HD with a 6.0 gas 130,000 miles and I was averaging 12-13 mpg. That was the reason for taking the picture. I was so happy to be getting such good consistently high mpg that I took the picture. I love this truck! I had been driving Chevys for a few years and I am so happy I went back to Ford. No regrets even if my mpg do not bounce back up. Thanks.

 

Not sure how many miles I have driven over my lifetime of almost 60 years behind the wheel. I have always played a game of chasing mpg, just for fun on my many trips. I can say if I just take the cars and trucks I have owned over these years I am def at 1 million miles.

Asking about MPG is like asking a fisherman about the one that got away...If they post a pic when many do you need to run the number. Sure it says 40 mpg but when take time/mi you often find the 300 mi trip was driven at 35 mph.

And of course there is the: I don't trust the computer so I hand calculate...YEA and that is accurate???

Your mpg is fine and well with what to expect.

LOTs of factors come into play with mpg, fuel, wind, rain, uphill/down hill etc etc.

Several years ago my offroad Jeep which mpg in the 12's on a good day with its 37" tires, lift kit and supercharger. I was doing some work on it and had removed the roll bar to windshield braces, so the shield was down. I get a call from a company and some parts I ordered had arrived but I had to pick them up that day or it would be over a week before I could get back up there. They were located at the Ok line on I 35 and I was in Ft Worth. With luck it was summer and so off I go sans top and windshield. I needed gas to make the long trip so I filled at just down from house at my regular station. I am a top off guy if I am traveling, so I filled to the brim. I drive up spend a bit of time to sort out some engineering details and go outside and WOW, storm coming in and the wind is howling, blowing S the direction I am going.

With no windshield you can drive fast unless you have goggles and I had none, so about 40 max and barely keeping my sunglasses on my face. As I get home ahead of the storm by a fraction I note the gas gauge and the needle looks like its barely moved, heck I should have used a ¼ tank or more, so I fill back up to the brim at the same station and it gives me 26 mpg...just shows you what wind resistance and a tail wind can do...

 

What you have said is so true. Sometimes the stars align just right and the fuel gods are on your side. Back in 09 my wife and I bought an 06 Wrangler unlimited or LJ. We took it on a Vacation from Northern Kentucky to upstate NY in the Adirondack mountains to visit family. I drove for maybe the first 8 hours or so stopping frequently for gas. Since the little thing only held 15 gallons we had to stop very often not to mention our two young sons under the ages of 4, Anyway I was trying to take it easy driving the speed limit windows down to save on fuel keeping the A/C off and the rpms low in the attempt to squeeze ever little bit of fuel economy out of that 6 cylinder. The best i could do was maybe 18 with those stock little doughnut tires. Well I got tired and so my beautiful bride took the wheel. I dosed off for a while and when I woke up she was doing 85 in the high speed lane A/C cranked up and I was mad. When we stopped for a fill up I couldn't wait to show her the amount of gas she wasted by driving so fast. To my surprise it was better than any numbers I had while I was driving. I knew I must have made a error in recording the millage traveled or something. So this time i made sure I had the right millage written down and we where off. She was behind the wheel again I was holding my tongue the entire time until it was time to fill up again. I knew I could prove my point this time! Well I filled it up and did the math and well I was wrong again somehow she managed to do better than ever once again.. It just goes to show that you can never predict mpg! Any way thanks for listening....

 

My LJ would yield 19 mpg on a good day but mostly 17-18 day in day out. Loved that car, should have kept it..

 

OP -- mpg will be an increasing concern for all truck owners. Oil prices have been on a tear the last couple of months and while it's not completely showing up at the retail pumps, inventories across the globe are falling, pretty noticeably.

Bottom line: diesel prices have directly benefited from the US Shale (Tight Oil) production . These "frackers" produce loads of mid distillates (diesels), but they're draining the wells rapidly (depletion levels are ugly).

Prices are going to go up significantly in 2-3 years. Days of $4.00-$5.00/gallon diesel are coming again.

 

I'd bet the winter grade gas .

 

Generally I will disagree with you, having said that we have gone from a massive over stock to bbl price that more truly reflects the cost of production + profit.

The price of oil is determined by the global market and the overall costs to produce new oil. I have some friends who and 3rd generation who live out in the "patch' or Permian Basin of Texas. They have wells that make a profit at $12 per bbl, these are wells drilled by dad and granddad. The is little of that around the world. The Tight Oil (aka Light Tight Oil or LTO) has been a boon to the world. Estimates vary depending upon who you ask, but about 500 BILLION bbls.

We have ample oil globally, the real issue here in the US is the attitude of the far left which dominates politics in NY, Cali and to some extent Fl, who thinks it will endanger its beaches. We need a drill here drill now mentality!

There are still some wild cards out there the the biggest and nearest is Mexico. There has been almost no exploration below 9000 ft due to Mexico's inability to drill below that (they are working to resolve those issues but the oil business is controlled by the Constitution in Mexico and the country uses it to pay the bills as its state owned).

I have friends on both sides of the coin, some thinking that Mexico could hold some of the largest oil reserves in the world and some who disagree thinking most of the oil is shallow well <9000 ft.

Bottom line is that free market calls the price based upon supply and demand, but then the pesky demon of cost of production creeps into the picture and directly affect the supply side...if you can't make a profit, then you stop drilling.

While I miss the cheap oil of the past year, they were not making money at it so it took a while for the price to rise and drilling and production to resume. I think it close to settling in at a balance. Today its a $63.50 West Tex sweet. At $60 per bbl money is made by the bbl full so the fields are producing like cray. I was just up in the Permian basin the other day on business and things are doing very well....

 

I have a 50/50 commute between back roads and highway daily. I consider myself a pretty conservative driver and usually drive the speed limit when traffic allows during the morning and afternoon rush traffic. When I had my 2002 F250 2wd Supercab SB 3.73 gear V10, I usually got between 13 and 14 mpg with the occasional 15mpg.

When I purchased my 2008 F350 2wd CCSB 3.73 gear 6.4, I read on these forums mpg wasn't much better. I will say the regens on the 6.4 was terrible, and I hated it. I ended up deleting and tuning it which was probably the best thing for that motor. After deleting my mpg was a consistent 16 to 17 mpg with the occasional 18+mpg.
I track all my fill-ups on my apps. With the 6.4 I always pumped until it clicked then went another 2gallons.


This pic shows the mpg meter was off by about 2mpg.


When I purchased my 2018 SD F350 4x4 CCSB 3.55 gear 6.7, I was a little worried my fuel economy would suffer upgrading to a 4x4. To my surprise my first few fill-ups have been promising considering winter diesel usually renders worse fuel economy.


As you can see the mpg meter is off by about 1mpg.



This new F350 IMO is a beast compared to my previous F350 and drives very smooth just commands the road.
