Ram 3500 MPG test

13.9 unloaded calc VS 15.1 I can tell you that is a bunch of BS.

I recently did a 380 mile round trip PS CA to SanDiego CA and back. I filled to top each time. Truck said 15.3 my hand calc 15.13. My hand calc VS computer is at the most .4 low to right on. Never higher than computer. My odo is right on.

How did he do the fuel and re fuel? I guarantee not to the top each fill.

My truck is geared the same. So 15.1 IMHO for such a short drive is good.

These economy tests are a joke until they fill the truck to the top with truck setting in exactly the same spot on each end of the test.

The unloaded mileage mileage being off and loaded being close to the computer tells you how **** flawed his test system is.

It is possible the P O S CP4-2 pumped trucks are yielding less mileage than your 385/865 CP3 pumped truck.

My 15 always EVIC always is overly optimistic on fuel mileage both loaded and empty. Only once in a while loaded does it get pretty close.

I am anxious to hear from “ford truck guy” when he gets a few tanks thru “BlackBetty”

Here's an empty mpg test where the same person tests his 2019 Ford against his new 2020 Powerstroke. He gets a 30% improvement (18.9 mpg) with the 2020, although his 2019 had 35's on it.
So, maybe, between the 2019 Ram getting a little poorer fuel economy then previous models and the 2020 Ford getting significantly better fuel economy .... maybe this TFL test is not too far off.

And the last paragraph!

"There is one reason to buy this truck, and that is to haul and tow anything and everything. With poor fuel economy when empty and comparable to its class when heavily loaded, this truck is meant to be used as a workhorse. Having the extra wheels in the back makes city driving and parking difficult and even annoying. On the flipside, it remains stable and composed while hauling very heavy loads and never feels short on power. Of course, it does all this with an excellent ride and comfortable high-end interior."

Pretty simple, people buy them to do a job!

one thing i noticed from the videos, was the miles each truck had. the ford almost 4500 the chevy around 3300 and the ram, only a little over 1500. never have i owned, a vehicle in which it did not get better fuel mileage after it had a couple thousand miles on it.

Good point, but it's a small difference.

I think it's pretty tough to argue that any one of these new diesels is more dependable than the others and this thread is actually supposed to be about how Ram/Cummins is not even in the same league as Ford when it comes to efficiency. If Cummins isn't concerned about keeping up, Ram might have to try to negotiate a deal with Ford to supply them with engines.

That is if you go off of test like these to rate a vehicles efficiency. There are too many variables when doing tests on different days and even different times of day. A tail wind on one day could make a huge difference on a headwind another day. Case in point, when they tested this same exact truck configuration last year on the same loop towing a 29k fifth wheel horse trailer, they got 8.7 mpg.

If you go off of real world data like Fuelly where people post millions of real world mileage(which matters more than this test), the new Powerstroke 10-speed seems to have merely just caught up with the Cummins. Before 2020, the Powerstroke F250 averaged 14.5 mph while the 2500 Cummins averaged 15.4 mpg. The few 2020 F250 postings(3 members so far) are showing a 15.3 mpg average, but that is too little of a a group still to tell just like the new Cummins 2500. The F350/3500 is harder tot tell because you don't know the mix of DRW and SRW and they are used to tow more than F250/2500s which makes it harder to get a good average.

I would be surprised if the Ford got 30% better MPG than the RAM, but I also don’t think fuelly is as accurate for comparison with these two trucks.

A 2500 RAM has the lower output engine due to the transmission doesn’t it? Does the HP engine with the Aisin get the same MPG as standard engine with the 68RFE?
