On the mileage article there are two first gens. Old project rust bucket gets 27 mpg? What, how did that happen? My 91.5 with O/D has seen about 23. Weighs about the same, right at 5,000 lbs.

 

Read the WHOLE article...

Some of them were cutting off the engines and coasting downhill...

Most at least slipped into neutral.

ALL drove like grampa - very easy starts, slowing down WAAYY before needing to stop, trying not to stop completely...

Not exactly like you'd drive everyday.

 

yah with those techniques I'm surprised we can't get more than 27 mpg! Either way, I like the fact that I can flog the beast for the entire tank in the city or on highway and know that I will get a solid 22mpg This is with the fueling set where my boost maxes at 35 psi...

 

I'm with you! I've been flogging mine for the last couple weeks and I'm still getting 22 city/highway combined. Imagine if I put eased up on the loud pedal. I think I could get 25.

 

That is user's JQmile's truck. The techniques described when done safely will help your fuel mileage.

 

27 is pretty good for that truck really. Its an auto no o/d. I got about 21 when my truck had that combo, 17 once modded, and now 28best with overdrive/3.07.

 

Yea i read the same article and couldnt figure that out?!... he didnt even bump the timing!! that thing could get 30 i bet if he bumped it 1/8!

 

its very good, but not realistic

did anybody see the crew cab 1st gen in the "reader rides" section. very nice looking truck

 

Those DDP injectors are supposed to be real good for mileage. Maybe they really are. They ought to be for 800 bones!

 

Yea, that's a great looking truck. I think it appeared in the mag once before.

 

why not,i have the identical truck and have gotten over 30,always 25 + stock ,timing bumped,most mileage has to do with the driver,push hard on pedal,you pay

Ahem......... My ears were burning.


Seriously, though I drive like said above, minus shutdowns and coasting in neutral, and get 17mpg.

I figure I'm losing a couple to the mud terrains, a couple to the ULSD, and a couple because I haven't gotten to the IP yet.

 

Yea you gotta remember that rust bucket has stock timed pump. With the pump against the head he may have hit 30mpg. I regularly got 27mpg on I-10 from Katy to Houma, LA. Thats cruising about 63-65mph, so a lighter reg cab would do really well.

 

Gotta say too, my LBZ Dmax has never gotten better than 23 with me driving Ms. Daisy. I dont know how they got those things so high.

 

The article said they have some special tune on the one d-max.. but seriously thats unrealistic because not everyone has that tune on there duramax..THEY SHOULD HAVE USED ALL STOCK TRUCKS!.
