2016 Duramax vs 2002 Duramax Mashup

Makes me miss my 02 dmax Silverado. New trucks are soooo quiet though.

Cool comparison but would have rather seen them run at 65mph with both in 5th.

They're wrong about why the '16 got worse mileage. Has nothing to do with the higher output OR weight since combined weights were identical. Its ALL about the emissions components... Delete the '16 to let it breathe and it would have probably gotten close to 12mpg. They also failed to say (if they even knew...) if the '16 did a regen cycle in that 100mi loop which would have significantly changed the numbers.

FWIW the MPG readout on the '16 is about as far off on the high side as my 2012.

Yep I thought the results were interesting.

To determine fuel used by clicking off waiting 30 seconds then squeeze/click is a joke.

Thanks for posting!

Imagine that. An engine with almost 100 more HP with A DPF getting less mileage than one that doesn't. What the hell did they think it was going to do? :S :R

Please explain...

They are just using consistent/repeated technique when filling the tank each time. I don't see the problem.

What do you propose they do?

No two tanks are going to cause the fuel nozzle to shut off a the exact same time every time. If they filled the tank to the top each time would be more accurate. But they may spill a drop so that is not an option.

Only real accurate way would be tie a seperate fuel tank into system that can accurately be re filled to determine exact fuel used.

filling at the same pump each time seems good enough to me because of the same level of the concrete. This is not that important to keep going on. Just watch and enjoy and forget is what I do. Lot more important things to consider in life.

It doesn't matter if one tank consistently fills more than the other. Its irrelevant... THe key is to consistenly fill the same tank to the same (or close ot the same) level at each fill. Whether one fills to the top each time and the other always has a gallon of space left doesn't matter. As long as its consistent each time your only measuring what you are able to put into the tank. By using the same pump at the same station using the same filling technique (fill till click, wait 30sec, and top off)is about the best you can do in a test like this.

I agree it's as good as THEY are going to do.
