That site is full of massive fail. Dodge is not listed for 2001.

Not til '04 I think. A friend sent the link to me the other day and once I found a Cummins, it said 15,000 miles.
That's what I do anyway, even though I don't have a somewhat cleaner-burning common-rail...

Yeah, it does seem to be right for everything I've put in. Says 10,000 miles for my Mustang which matches Ford's claims.

Once every two years. Or at least I should in my truck. Unfortunately it costs a fortune and I dump gallons, GALLONS of oil into it. Only put 2K miles on the truck though.

So it's a 7.5ish liter inline-6 diesel with multifuel capability. What's the oil capacity?

22 quarts of oil, which is like 100 gallons if my math is correct. It's expensive that's for sure.

My dad's 87 N-14 Big Cam Cummins took 10 gallons of oil and the 97 with a C12 Cat took 9 Gallons.

I should check the oil in my truck , I think I changed it some time last year.

I generally run Cummins-endorsed Valvoline Premium Blue, but I do throw in synthetic Rotella when it goes on sale...

I'm at about 5K on the suburban, which is what I like to run.

I never go over 4k miles, and I change it closer to 2k. City miles are hard on a car, especially when you drive 35k a year

That site says 6k. I usually get to around 4.5k before the car starts running rough. The engines that Chrysler put in the Sebring is fairly well known for gumming up. Even with synthetic, it starts running worse around 4.5k. I've tried Mobil 1, Royal Purple, and a few different brands of dino. Same thing. Synthetics do run a little better than dino, though.

2.7, Curtis?
They're terrible with the sludging...

Yeah...

Hoping to replace it with a 2012 or 2013 Audi A4 or A6.

I change my F-150 every 5K miles with Motorcraft synthetic blend 5w20 and FL20S filter and my Explorer every 5K miles with Motorcraft synthetic blend 5w30 and FL20S filter, and my BMW every 7-8 K miles with BMW full synthetic oil (supposed to be good for 15K miles) and Mann filter.

My sister had an '03 Stratus ES with the 2.7 which put itself among the elite...it made it to over 100K miles before oil sludging issues. She changed it every 3K and it ran well until about 120K.

Change it when it's carbon filled, and screw the averages in the book.
