'22 Powerstroke seems a little thirstier than the '21 was.

[4x4ord]

I'm getting the idea that my '22 F350 (which should be exactly the same truck as my '21) uses at least 15% more fuel than my 21 did. I calibrated the fuel meter on the '21 but I'm not confident that I have the '22 set right ... I haven't filled the truck using a legal for trade meter yet. Filling only to the first click off, the meter I have been using just told me it took 132.5 litres to fill my 128 Litre tank (I figured I had 2 litres remaining so 126 litres is what I was expecting). Has anyone put more than 128 litres/34 US gallons in their 128 litre/34 gallon tank? Even if my pump meter is out 5% I'm feeling quite confident that my '21 was consistently getting better fuel economy.

Something seems to have changed. With my previous Powerstrokes it seemed to me like the mileage I got on day one was not much different than the mileage a year later. Anyway I’ll be happy if it keeps getting 21 mpg.

did you purposly put the US mpg in there? I saw it and I went that sucks, as for us canadians you got 25.4mpg.haha

I included the litres per 100km cuz I figured no matter which way I went with mpg it would be confusing.

How do you change the calibration?

1. With the ignition off wait until the interior lights and screens have completely turned black.
2. Hold the OK button in the left side of the steering wheel for 5 seconds.
3. While still holding the OK button press and hold the start button until "ET" (engineering test) displays in the lower right hand corner of your DIC... Release both buttons.
4. Press OK to acknowledge any warnings screens (door open etc)
5. Press the steering wheel arrow up button to get to the AFE 1000 bias screen.
6. Use the left or right arrows on the steering column to lower or raise the value. Lower number will make the mpg display less generous. So if your mpg is displaying 8.5% too optimistic you would change the value to 915 (91.5% of 1000).
7. Press the OK button to store the new value.
8. Push the ignition button to shut off ignition and exit "ET" mode.

Only real way to know is fill er to the top every time!

I haven’t found it very useful to try and check accurate mpgs. As regardless of the accuracy, the only info I would gain is exactly HOW bad of mileage I get when doing 90mph on my morning commute and 95mph on road trips! Lol

the fuel meter was perfect on our 05 because it was dead on with the math and the fuel used but in 09 the cluster gears went out in the speedometer and after the repair that was a recall it was not accurate even after some flash at the dealer but it was very close. Our equinox is right on. chevman

Dad just bought a 14 RAM 3500 LB 3.42's AISIN. Drove 130 miles on I-5 60-75 mph. Lie O meter said 19.5, I was IMPRESSED!!!

Only a couple trips towing double , haven't seen anything change as far as mileage .

The 2nd trailer takes a ton of stress when you double tow. I think it is because the connection point is so far back behind the first trailer axles.

I've double towed since about 2000. In that time, I have broken the hitch on the back of my trailer, broken the weld on the tower that holds my boat winch, and broken the weld that holds the pin on my brake away tongue.

In 2014 I had the rear of my 5er reinforced, along with the hitch. A welder reinforced the frame of the trailer all the way forward of the axles, and put on a very heavy duty hitch.

I'm done towing my big boat, but still tow a 17' Ranger.

Anyway, keep a close eye on all potential failure points. They are under considerable stress.

Glad it ended well for you.

Good advice! My great friend is a Machinist and metal fabricator. He has lots of experience in rebuilding trailers etc. I will get it to his shop and we will beef the HE!! out of it.

I will call Kendon tomorrow and see what they say. It is a two bike cruiser rated model.

Thats pretty scary , that shouldn't be coming apart like that . . I have built a few ,and they don't come apart . If you were around here , when I got done with your trailer it would stay together for sure .

I too tow double , and I can only see the shadow ,keep thinking I want a camera back there ,but haven't got one yet . I rebuilt this small 10' trailer that I tow double ,no worries about it coming apart ,but it would be nice to see the load on it, what it is doing .

^true that...and I think that most, that tow double, actually reduce their speed a little, that evens out the mpg of towing a single trailer.
