What they are doing is NOT accurate. You can't see into these newer truck fill holes. There is a flapper down a bit.

They don't even stick the nozzle all the way into the hole all the time as this will make a difference when it shuts off.

YOUR truck I am sure you can look down into the hole and see the fuel just like my 98 and 01 RAM's are.

I can see the GM and Ford getting better mileage if their rpm's are lower than the RAM's at 70 as 4X said the Ford is.

Bottom line I sure would NOT buy a truck based on their VERY unreliable testing.

Like I said I didn't take anything into account for tire squat so if your truck tires squat 1/2 inch you'd be traveling 70 mph at 1975 rpm. The Ford with 1/2 of tire squat would be 1730 rpm @ 70 mph.

"or is it possible your tac is off?"

WHATTTTT??? Something "OFF" on my truck???

^^^^ 1900 is based off the correct gear ratios and a 32" diameter tire for the Ram. 1670 is based off the correct gear ratios and a 31.5" tire diameter on the Ford. The calculated speed doesn't take anything into account for slippage or tire squat. If the calculation is off on one truck it should be off the same % for the other..... or is it possible your tac is off?

My tachometer says 2,000rpm at 70 so the Ford running 1,670 would for sure get better mileage. That much difference with the wind who knows, I doubt it.


Seriously these guys need to learn how to fill up a truck!!! To be "PRECISE" they could have a 5 gallon container filled and mark the tank where the 5 gallons comes to, fill truck tank with nozzle til it shuts off. Fill to the top with the 5. Empty the 5 into the chase truck or have a second tank empty and then fill it with 5g.

Now take the run come back to the same pump so the truck is setting the same. Have a container with exactly 5 gallons in it. Now fill the tank til it clicks, now pour from the 5 into the truck til it's FULL. Now fill the 5 that you just used back to it's full line using the same pump to determine exactly how much fuel is used.

I know this sounds complicated but in reality it is not and would give EXACT amount of fuel used.

Do the same with the DEF, it's simply stupid trying to get an accurate number with the DEF pumps.

^^^^^ Why do you like gas?

Hmmmm, the 7.3L gas Ford is starting to look better all the time....

Ford would have been running about 1670 rpm and Ram about 1900. I'm going to need more convincing before I"m going to believe that the Ford gets that much better fuel economy than Ram just like I'm needing more convincing that the Ram exhaust brake is that much stronger than Ford's.
