3.0L Duramax - who owns or has driven one

[ArTurf]

So approximately how much does the DEF fluid add to yearly cost, say you drive 12-15k a year? Just looking for a general figure

DEF cost is peanuts, compared to the other costs of ownership.

 

Usage will be about 1.5 or 2% of fuel.

Using a my current 6.6L as an example.

It runs about 1100 or 1200 miles per gallon of def. 

 

Average US DEF cost is about $2.75 (according to google search).

 

15,000 miles/yr  / 1100 miles/gal  x 2.75 $/gal = $38 per year.    

 

FWIW, avg diesel price/gallon is about the same.

 

 

I never understand all the folks that say they won't buy a diesel because the cost of def is so high....

Clearly it's insignificant.

So, what about the other cost of ownership?

 

Are you talking about oil changes, insurance, truck payment.

 

I would get a 3.0 mainly for mileage, the most I tow is my garden tractor.

 

My current vehicle(Honda Pilot) does not handle towing very well.

I was referring to the costs that will be in place no matter what engine is selected. 

Financing, depreciation, insurance, tires and so on. 

 

Oil changes etc will be similar. 

Diesels will have replaceable fuel filter -- but like DEF, the cost per mile is tiny.

 

and so on.

I don't see any additional expense with the diesel, except the fuel costs more. The oil change is probably a little more, DEF cost, and fuel filters. However there are no spark plugs to change, no coil packs, no wires.

...there are injectors and glowplugs instead...  The higher compression also may result in a higher likelyhood of blown head gaskets.

[ArTurf]

Another question, How much more does the 3.0 weigh than the 5.3/6.2? Just wondering. Part of me wants this engine over my 6.2

I doubt that. It's not like that the 3.0 is the first diesel ever invented.

It might weigh less.

 

Haven't seen a weight calculator for 2020.  (Most years they have published one).  I checked the 2019 one, and didn't find LM2 info included. 

 

2020 curb weights show the LM2 crew/short/4wd weighs less than the L87 crew/short/4wd.  I think they're both gonna be 10 speeds.

It's not that this particular engine is more prone to blown head gaskets, but in general, perhaps because they see more miles, or that they are more expensive, so people are more likely to repair vs replace, but diesels seem to have blown head gaskets more frequently than gas engines, and a head gasket repair is more expensive compared to the same problem with a gas engine.

 

And, for the 3.0 engine, I believe there is that belt at the back of the engine that has to be periodically replaced every 150k, which is a fairly expensive thing to replace...

Looked it up it weighs the same as the 6.2

What does this belt drive?

[Whipped500]

The belt drives the oil pump.

 

Nobody has replaced one yet as far as I know so we really don't know what it will cost. From a video I watched, a GM engineer said/made it sound like you disconnect the trans and slide it back a little bit and then there is a service plate to access it. Probably not ideal for some but not as bad as some are making it out to be. I've heard people trying to say the engine has to be pulled to change! Lol

Nonsense.
