re: Ram 1500 ecodiesel

That might have something to do with why the OCI is so low on this engine. 10k miles with 10qts of full synthetic oil is not very good considering gas engines are doing that and more with less oil and synthetic blends.

If you've ever smelled used oil out of a diesel truck, it smells almost like straight fuel. I am guessing since USLD is not a good lubricant like old diesel, they want the OCIs to be much shorter

ULSD has other additives to make up the lubricity for the fuel system. Unless you have major washdown then that shouldn't be the issue. I would expect it might be the oil shearing down from the high pressure drive of the fuel system but a full synthetic diesel oil shouldn't have that issue considering it isn't an issue with domestic turbo diesels already running high pressure oil to drive fuel injection. CTD has a 15k OCI with 12qts of conventional diesel oil. You can pull the oil pan on any current diesel that has been properly serviced with hundreds of thousands of miles on the bottom end and you will virtually zero varnish that comes from fuel byproducts you'd see in a gas engine. Modern HDEO's are damned good so I would hope there is a good reason for a 10k OCI.

If the diesel gets 23 mpg and the hemi gets 14. The price could be more than $1.35 per gallon and the diesel would still save in fuel per mile.
Around the $1.50 difference they would be equal. This is just mpg.

Diesel engines typically get a little better highway MPG than the EPA numbers. Diesel fuel also has greater energy density than gas...enough so to where the increased cost is usually more than offset.

Does your calculation include DEF fluid?

Let's just say he likes it enough that he's getting another one to replace the one they can't figure out how to fix.

Nope. Just fuel per mile.

Doesn't matter. In the grand scheme of things with a private vehicle, DEF is negligible.
People don't realize how great SCR is. Yes it is complicated and expensive up front, but if you really need a diesel, SCR is the best thing you could have ever hoped to get. New diesels are stupidly clean and powerful without running retarded EGR flows. The diesels out now are what every company has been working towards since the days of the mechanical smoke belchers.

Filters and soot load.
I highly doubt you ever see separate numbers for filter and oci for consumer vehicles.

Most cars in Europe are diesel now I understand.
What I do not understand is this huge premiums US manufacturers want for the diesel engines.$3-5000 is just too much.
I don't think the economy of a diesel will pay now. You can get 20 mpg V8s in half ton trucks now and the eco 6 in fords. With at 60-70 cent premium for diesel it just doesn't pay off.
The life advantage is nothing like it use to be either. 250K is really nothing extreme for a gas burner now and who wants to own a truck for much longer than that??

Diesels cost that much more. Aftertreatment systems are insanely expensive, and dual fuel pumps, and electronic injectors, etc etc
It costs a lot to make one of those things.

That's the truth. Gas engines may be even more reliable than diesels now. We have 200k on a suburban. Engine still strong.
Rest of vehicle is falling apart

Diesel isn't the answer for longevity or low maintenance anymore.
The guts will last forever, the rest of it will not.

Thanks for all the replies. I've started looking for a new truck for the first time since since 2002. I've always had Chevys, but have been looking at a new ford xlt 4x4. I just started looking at the diesel dodges because of the gas mileage they were advertising. Between the 2 trucks, what says the OB?
Posted on 11/5/14 at 7:48 am to riverparish
Most of the OB will tell you Ford. Just go drive them all and see what you like. And if you're testing Ram's, make sure to test both the diesel and the hemi...same with Ford, test the ecoboost and the 5.0.
Posted on 11/5/14 at 8:02 am to riverparish
Ram - but you really aren't comparing similar vehicles (other than they are both trucks) so it will be your decision after driving them both. Pick similar trim levels and creature comforts and drive em both...

Why? People are lining up to buy them. Why in the world wouldn't they charge that much?
