well there is the fuel filter, but you can always ask someone who has a gasser how much it would cost to change the fuel filter on their truck? (It's in the fuel tank and part of pump).But is the cost of maintenance really that much more than a gasser? Other than oil changes (I do my own) what other additional costs? DEF I guess.
DEF cost is outrageous I tell you... something like $0.001 a mile ...lol
If you watch for sales and rebates on the oil, you can get that $$ closer to $70, if you use a different filter now it's $60ish.An oil change cost me about $35 to do myself. An oil change on my ED (using a mopar filter and rotella) costs me about $100.
I'm guessing that $35 oil change wasn't a synthetic. Now compare that to Hemi oil change using 7 quarts of premium full synthetic oil and OEM filter. The price isn't all that different.
