Ram 3500 MPG test

My truck gets used as a daily driver and essentially gets driven every day.

That is a lot of idle hours! Using the standard of every idle hour equating to thirty driven miles, you technically have 217k miles on your truck.

Fish was right, I was getting over 45 mpg mixed with under 45 mpg. My mind was thinking something differently than what I was typing.

Very rarely do I get above 45 mpg and if I do on a normal work week commute the whole tank then I know the tank is not full. The 47 mpg below was from using the car to drive to Austin(80 miles one way) for a quarter of a tank one weekend and the rest of the tank was my normal work commute.

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.

I might agree with you if I was buying a Ford but there is no way I would walk away from a test where the Ram used 30% more fuel than the Ford saying "they both basically used the same amount of fuel. I think I'll buy a Ram".

In this test of one, yes. But you'd be a fool to conclude that, based on this single test, the Ford is 30% more fuel efficient than the others. If that proves out over multiple tests from multiple sources, then yes. The most power, a 10 speed auto, and the best fuel economy? Certainly a winner.

I concur.

I agree... But there's also One that stands out from the group!

Let's see after some time and a few miles... ;)

Maybe we can all be honest and agree it’s a BS flawed testing method.

It doesn’t matter if one brand fills differently from another brand. What’s important is the fill method is consistent from the initial fill to the second fill to calculate fuel mileage and I will say the method used in this test is good.

Also I’ll second what John Deere farmer has stated that the new Power Strokes are making better fuel economy and people are noticing it.

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 still don't understand your math.
