The crd takes a higher grade of oil and more of it; hence more money, the fuel filters are required every 15k, not on the hemi; hence more money. I've heard of people having multiple issues with various parts on the crd (not saying all hemis are bulletproof,) and parts are more expensive due to it being a Mercedes product; injectors, turbo, dpfe, etc. And I do all the work on my Jeep myself as I am an ase certified tech
Other than the swirl motor issue and occasional glow plug issue....can you please link to all these turbo, injector,and dpf failures that you mention above.
Increased price of CRD oil/filter and fuel filter will be offset by the increased fuel economy of the CRD. Chrysler also recommends 89 octane for the Hemi which pulls the price of gas closer to diesel.
Hemi oil change = every 6000 miles (7 quarts) service a (there is not even a severe duty option for the Hemi...just saying)
CRD oil change = every 12,500 miles (10 quarts) service a
CRD fuel filter = 50,000 miles (service a) or 25,000 miles (service b)
So you are using 14 quarts of oil in the Hemi every 12,000 miles while the CRD is using 10 quarts every 12,500 miles.
The only maintenance difference is the fuel filter needed for the CRD. That is about $30 bucks every 50,000 miles.
