What does your warranty say about that and what are you defining as "extended drains"?
Manual says:
Quote
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km) or 12 months, whichever comes first.
What I would consider extended drains is anything beyond the point where the OLM says 'times up', or beyond 10,000 miles.
I plan on some sort of bypass filtration if I can fit it somewhere. But as I think I mentioned earlier, fuel dilution may put the kibosh on the whole thing.
If this engine has a 7th injector for the DPF regens, then fuel dilution should not be an issue. But given the cost of anything associated with a diesel is $$$, I would buy the extended warranty (not sure if they offer the 7 year unlimited mileage MaxCare for the diesel like I bought for my 3.6L) and follow the service schedules to keep the warranty intact.
Ecodiesel does not use a 7th injector, it uses "post injection", on the exhaust stroke it fires the injectors to put fuel into the exhaust to regenerate the DPF.
I've never had a fuel dilution issue.
Initially my jeep had 10,000 mile oil life monitor, I never go that far, then subsequent software revisions have taken it down to 6,000 miles. I've used CJ-4 5W40, or 10W30 oil since day one looking at how weak the additive was in euro diesel oils were.
Definitely recommend adding Maxcare, you can buy it online cheaper than what the dealership's offer.
