how often should you change your oil?

This site has the answer supposedly.

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...

[cowman]

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?

doesn't go back to 1983 so i can't want pray game...

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

Gotta love military applications. My 5.9 takes 14...

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.
