Colorado, Canyon to receive four-cylinder Duramax diesel options

[milner351]

My dad had a shop truck for 20 years - a Isuzu diesel, 2wd, long bed truck. We beat the living snot out of that truck, and the worst mpg it got was 45 mpg. We used it like a 1 ton - e.g. we put a 20' commercial vent hood on the ladder rack (~500 lbs), 48x60" flat side - and hauled it to Seattle. Got 45 mpg.... top speed was 55.

That's the yardstick - if the truck does better than 30mpg, my H3 will find a new home.

Yea - that's the thing lots of Americans remember about diesels from the 80s - they got great mileage but were abismal in the acceleration power department. It's easy to not use much fuel when you can't make much power.

I wonder how often you'll have to refill the urea tank?

top em off at oil changes
another reason diesels don't sell

those diesels assured my quest for foot pounds.
Changing amount of air fuel is easy as hot rodding.

the Mercedes hack is the funniest of all time. A drill bit, 5 minutes and a holset turbo.

I drove a old 50hp rabbit (very old rabbit diesel), about 100 foot pounds, a later jetta, rattle trap..but more foot pounds, needed constant adjusting at the valves until head failed...at the valves....and a rare Nissan pickup, 1 drive, something overseas would get. I made up my mind then..my life is foot pounds.

the little boxer wins the whole damn thing, but I am very interested in the four banger diesel...especially turbo in modern control.

I have a diesel from the 80s - I honestly don't care whether or not I win drag races with it. I do love 20 mpg in something with a bed and 4000 lb carrying capacity.

To me, it's an arms race that just doesn't make sense. Sure, the 80s diesels measure 0-60 with a calendar, and a bit more is nice (hello turbo); but then it just got stupid.... spend 60k for a truck, spend another 20k to make it run faster - to what point? now you have an unreliable pickup with the fuel economy of a top fuel dragster... spend 60k for a truck, buy a Fox body put a turbo LS motor in it and go racing... you'd have change from the 20k....

so yeah, I'm weird, I just don't get it.

that's why I have a ~$12k powerstroke. no $60k trucks here, never, even if I could "afford" one - it's a horrible investment.

I'm betting a turbo will be involved this go around and will drive like a gas motor (and probably effect mpg's like a gas motor). Topping off the urea tank at every oil change sounds reasonable to me.

every thing is turboed
good , until the turbo fails

that's the oil change you're talking about... my turbo has the original rust on the pedestal bolts still at 260k.

and the world ends in a fiery crash ... still entertaining.

seriously, cars die.... all of them.

[SpiderGearsMan]

we had a rush of 2 Dmax turbos a few years back
then the price of diesel went up
duramax problems are fewer since nobody buys them ...municipalities just buy cheap ass diesel fords now

I wonder how this happens. The cheapo Holset on my 98 Dodge Ram lasted 355,000 miles before the trans crapped and it would cost more to repair than it's worth... so I parted it out. Turbo was in perfect shape. That cummins was the simplest engine to work on, and parts were cheap. A whole set of injectors cost less than ONE injector for a duramax.

difference that you missed is you took care of yours, as most car/truck people do. it's the other 95% of vehicle owners that just drive them, and have no clue on what service means other than when the idiot light on the dash comes on that says "check engine" or the "oil life light " reads zero . Did you ever think of why the OEM'S felt the need to add that feature? after see'n tons of cars with family photo's covering all the gauges/idiot lights in cars, I can see why they now offer service "reminder" emails/texts.. people think service is adding fuel to the tank..

We just bought a used Rogator (farm sprayer) with a 300 horse Cummins in it. I'm actually scared of it ever breaking down, there's more wires going in and out of it than the computer servers back at university. On the other hand, it's kinda cool to have one giant LCD screen in the cab instead of a dozen gauges that never work (which probably explains all the wires)...

Soot my boy .....ambulances not going into regen

Duramax has actual technology
Cummins was a tractor
