A Lil more miles then looking for but thx for the offer

 

I wouldn't really wonder about the miles, these Cummins' will make it for a million miles with ease...

Fix the KDP, get a decent fuel plate, tune your AFC and build your transmission and you will make another million miles without a worry...

Only thing i have to complain about in these trucks is that they are prone to rust...

If the chassis is fine, steering parts are renewed or 100% and transmission has been built (i prefer just the NV4500, but a built auto would do just as fine) these trucks will last forever...

Does anyone know what the highest milage is on a 12valve 2nd gen ?

I know there was a 1gen with 4 million something miles somewhere down in Texas...

One owner, looks as it was new...

 

I'm wondering if you have a little better fuel over there than whats available here, milage seems high for 4.10's and 35's

 

The Cummins factory in Columbus Indiana, send Dodge up to 700 6BT engines per DAY.

A whole bunch of Engineers mock the fact that Dodge are installing this engine in a pickup truck as it was designed for a duty cycle of 60-80% and could go for a 100% duty cycle for more than 1 hour with ease. This engine in a pickup truck doing normal load in highway / city usage will not even reach a load factor of 20%. In the past, Dodge used to compare internals of the Cummins vs NaviStar, Detroit 6.5 and the Duramax 6.6 as they have much smaller internals. This was even used as a marketing trick in Iceland.

Cummins engines will without a doubt outlive their trucks in every normal situation, my Cummins has got it's beatings and it still runs strong although now it has a faulty water pump...

My truck is listed in my signature (you probably have to look at my first post in this thread) and the chassis is screwed, wich is why i'm swapping into a 1500 Gasser...

That way i get a lot of cool features, like a lighter truck and short bed... but i will never EVER cope with my truck being a 5.9 gasser... so it get's a Cummins transplant...

I love my Cummins !!!

Not sure if that's right... BUT...

I do see a big difference in using the BLUE fuel here (OFF-ROAD, EQUIPMENT FUEL) or even the RED fuel (NAVAL, SHIPS AND SEA)... both in means of power and consumption...

The ON-ROAD non dyed oil will give me the best consumption, the BLUE is similar but will consume more and EGTs will be higher...

But this RED stuff we're supposed to use on the boats is "Radioactive" to say the least !!!

 

18-23 on the highway with my 12v and thats mostly stock. That would be my choice.

 

Guess this picture is in order for the new Cummins owner:

 

Awesome. Great info. Thanks everyone

 

I have a 98 12v 4x4, I run 33" Mickey T's and mine is mildly done mods wise around 400hp's and I get 22 to 26 mpg and I commute with it everyday. In the winter it's less, but still pretty good non the less. And mine has 565000 kms (354000 miles) doesn't burn oil, and runs like charm.

When I was looking for mine, mileage wasn't an issue. If you look at the truck, you can tell that it was taken car of. that's why I bought mine. will never own a truck that hasn't a cummins in it.

Avoid 2wd versions if you plan to be on anything but dry level ground. that fwd mounted heavy engine means the rear is light. forget boat ramps. I often get stuck in wet leaves on the level and have to go 4wd! Mileage if everything is perfect(valves, timing, working torque converter etc) will be 18-22 if you stay in the torque sweet spot of about 1700 rpm. Ive had 4 of these and empty @ 55 I can get between 20-21. Keep in mind your cost per mile because diesel last winter was $1 more than gas. Winter diesel will kill your mileage about 10%. These 2 gen 12 V rigs are getting hard to find cheap for lots of reasons including the lousy mileage and maintenance and cost problems in the common rail rigs.

 

ok thanks
