Ram 3500 MPG test

"there doesn't seem to be a stinker in the group."

I concur.

A 66 mile test with 3 trucks on different days, in varying, uncontrolled conditions is great for entertainment, but hardly statistically relevant. The margin of error is so wide that these 3 are basically the same. And yes, I would say that no matter who "won".

I think the Ford diesel engine is awesome. They have all had good and bad versions (some more than others), but these days, there doesn't seem to be a stinker in the group.

It's not the best test with diesel because it foams so much. If the tank is lower the first time, it'll foam more than when they fill with this method. Watch the half ton diesel test. One of them he actually says "wow that was a long second pull". Meaning they aren't consistent.

I have had this happen in my diesel trucks and cars on more than one occasion. It happens a lot on my current car because it has a smaller filler neck. If I don't have the nozzle in just right, it will foam up really quickly.

I can tell when it happens because I input my mileage in an app. I generally get about 45 mpg in my car since I only use it to do the same 80 mile loop everyday. If my app shows that my mileage is considerably less than 45 mpg, then I know it is not correct. One time it clicked way too soon so I waited for ten seconds to fill it up some more as usual. It clicked really quickly the second time as well. So before I put the nozzle back on the pump, I inputted the numbers in my app and it showed 41 mpg which I knew was wrong. I adjusted the nozzle and was about to get almost another two gallons more fuel in there bringing my mpg up to 45.

Some nozzles are finicky like that and different pressures in different temps seem to effect some more than others. It has happened a handful of times in my truck, but not nearly as many times as my car.

I can’t tell if your coming or going. Maybe you got your 45 mpg mixed with your 41 mpg.

Anyways being this sample test of 1 is not statistically significant it is very believable based on what I’m hearing.

I don't think that is possible with my aCar(Fuelly) app. I just put in the mileage before I get out to pump fuel and then input the amount I pumped in and it instantly tells me the mpg. If it is well below 45 mpg then I know it is not full.

It is harder to tell in my truck since I use it for towing and do not drive the same roads everyday like my car. However, back when I did use my truck to go back and fourth to work, I was quickly able to tell if it wasn't full if it was way off my normal mpg and had to adjust the nozzle to add more fuel.

I guess I am confused on your MPG calculation. If you see the MPG is low, you try to put more fuel in, and that makes it show a higher MPG?

If you drive 500 miles, then fill with 11.11 gallons, you would be at 45 MPG. If you put more fuel in, say another two gallons (13), your MPG is 38.46.

What am I missing.

"Ford for the win and the Cummins guy can't take it..."

Yea ok, I never said the Ford does not get better mileage. I did say it should get better mileage if it turns less than 2k at 70. I would be curious to see what they all get at 60 as that is where I tow.

I have consistently said it's a VERY flawed way to test mileage. One time they jamb the nozzle in all the way and another time it's 3" from being in all the way. One time there may be another truck fueling on the other side of the pump and then at refill no one is there causing different pressures.

But who actually cares?
Are things like gps within 1/2 mph of speedo or who gets 1/2mpg better or worse or how many clicks at the gas pump it takes to top off a tank a concern in your worlds, or just out of other things to nitpick and overanalyze?
If the latter, PM me. I have a whole host of actual real world issues (not with pickup trucks), that need solved....
