Purchased a 2015 F350 crewcab pickup with the 6.2L 3 years ago after being a diesel owner for the previous 20 years. I did not tow enough and just could not justify the cost and potential repair costs scared me. I am averaging about 14 mpg city/hwy. I do not baby it. I am looking for some feedback on anyone owning the 2017 super duty 4x4 with the 6.2L engine. I really wish I had order a 4x4 now and am thinking of trading. How is the mileage and what gears do you have. Thanks

 

3.73, mileage is the same as your truck. I noticed no difference between the years, but it's hard to compare fairly.

The 17 is better in many ways though. Don't test drive until you're sure you want to upgrade. Make sure to get the Fx4 option, and the E-locker. Both are cheap on a new truck, and expensive to add later.

My 2015 6.2L work truck has been a beast. It weighs 10,000# and regularly tows 6000# as well.
My 2017 personal truck is much nicer.

 

Thanks will keep this in mind.

 

I've got a '17 F350 CCSB 4x4 with a 4.30. On a 6 hour trip last weekend with the cruise set at 68 mph I got 13.3 mpg.

 

17 F350 XL 6.2 LB 3.73 4x4 w/18" wheels & AT tires - almost out of the 1k break-in and averaging 13.8 mixed driving burning 87 reg winter blend with 10% ethanol:

 

17 F350 XL LB 4.30 4X4 w/18" wheels and AT tires. Best I've gotten in the first 2,500 miles is 12.9 as registered by the on board computer. Have yet to tow or carry a load and I drive pretty easy.

17 F250 XL crew long bed 4x4 3.73 with 17" wheels. 1800 miles and it's sitting on 13.7mpg mixed. Towed my 8k dry TT with it, averaged about 7mpg at 65mph, no wind, small hills. Hoping that gets a little better with break-in. Its a nice truck to drive daily. Very quiet at highways speeds and good pep to the engine.

 

What is so great about the FX4 option? It gives you a small skid plate under the transfer case and a longer skid plate under the gas tank. It also gives you the poor Rancho shocks, and Hill Descent Control (HDC). HDC can potentially be useful, but it has also been proven here it can be added for $10 with FORScan to any truck.

The locker is much more valuable, but you don't need the FX4 package to get it. And probably most people will never use the locker.

To brangus82, the 6.2L is even better for 2017+. If you weren't aware, torque increased by 25lb-ft for this year, and even better...peak torque is reached 700RPM sooner. It makes the 6.2L better to drive around and better for towing.

Most people always recommend the 4.30 gears (if you opt for these you automatically get the locking rear end) but I've had a 2012 and 2015 6.2L with the 3.73 gears and they always worked well for me. I think unless your are planning on towing a large amount of weight and do so frequently, I'd probably opt for the 3.73 gears but optioned with the locking rear end.

For 2018, all 4x4 Super Duty trucks will come standard with electric-shift 4x4. You can still order a no-cost option for manual floor-shift 4x4 on XL and XLT trucks if that interests you. I prefer the electric shift only because of the automatic locking hubs.

 

I've got the CCSB with 6.2 and the 4.30 gears. Love the truck, it does everything I need it to do with ease. Getting an average 14.2 mpg over 10,000 miles. The Ranch Hand Brush guard I put on the front cut my mileage down around 1 mpg over the last 3000 miles or so. I think my mileage is actually 13.4 mpg now. Mine is a 4x4. Wouldn't have it without up here in Michigan.

 

I agree the FX4 package is a bargain.
My last three trucks have had this package and I've used it off road, a lot.
The skid plates work. I have never had a problem with the shocks either.

 

Gas tank skid plate, Transfer case skidplate, and the hardware that goes with them, and the HDC for $295. I think that's great.

If you want a stronger skid plate just take it down and reinforce it, or replace it with stronger plate. Fabbing those from scratch, or buying aftermarket, is going to be more than $295. But for me, stock Fx4 is likely plenty of skid plate. My previous F250 didn't have them, so I value them greatly.

The HDC is too cool. I love using it when wheeling.

I've used the locker 3 times already in 1 month. Super duties get stuck when making a tight turn off road around here. They get crossed up, tear the earth, then sink in like a rock. Break through the grass layer and down to super slick hard clay every time. Then it's one wheel peel on each axle until a little Dodge 1500 pulls you out. Then you have to deal with the Dodge guy rubbing his nipples like a crazy person. Don't get stuck with a crazy nipple rubbing Dodge guy. Get the locker.

 

You can buy the skid plates as a stand-alone option for $100. FX4 package went up at least $100 for 2018, but nothing is added. HDC, as I mentioned...$10. If the fake Rancho shocks which are well documented to be junk and the bed decals are worth $185 (more in 2018) are worth it to you, go for it.

What can I say...my truck is an FX4. But only because I bought it off the lot.

As for off-roading, I do a lot. This is this first of now 6 Super Duty trucks I've owned with skid plates. Given that the running boards, axles, differentials, and shocks all hang lower than the transfer case or fuel tank...I find them a bit useless. At least the FX4 on the F-150 gives you an engine skid plate, flimsy as it is.

 

How does one go about getting this? I apologize for my ignorance.

I have right at 5000 miles on the truck so far and the lifetime MPG is 13.8. I drive about 70% hwy 30% city and my weekly MPG is around 13.5 - 14.0 taking it easy running around 68-72 on the interstate. Last week I run the truck a little harder to see what the difference was and still averaged 13.0 mpg for the week. Also I do have the 275/70r18 tires.

 

6300mi - Avg mpg 11.6. Towing I get 8-9 and that's either a 5500lb boat or the 9000lb travel trailer. Empty on the freeway 13.3 to 15.4. 80% of my driving is city/rural roads with 2 mi of gravel so I probably get less mpg's than most.

e-locker and 4.30 are/were must have's for me. I also have the FX4 option and don't see why you wouldn't get it as it's pretty cheap if you go off pavement at all. So you can get HDC for $10...you need to spend $100 for the tool to make it work. It's a $295 option on a $45 to $70,000 truck.
