For those who have later model diesels, what is the difference in maintenance vs. gas? I read that the exhaust system has to be serviced regularly.
The newer DEF trucks don't have the same maintenance requirements that some of the earlier emission trucks had. If something goes wrong it would need to be fixed or deleted, though.
The increased maintenance amounts to more expensive oil changes (3 gallons of oil) and two fuel filters that need to be changed about annually. I just did all of it last weekend for a total of $150 (full synthetic oil, Fleetguard Stratapore oil filter and both fuel filters). Trucks with the Aisin also require more frequent transmission fluid changes.
