Just wondering since I did my first oil change and it was difficult for me to read the dipstick...

It showed right on the line after 12 quarts and I know its supposed to take 10, but when I drove it home from the shop it reads over safe and I know there are only 12 quarts in there...

Should I drain some?

I don't have my tools at home...

You'll be fine.

Thanks man!

Is it cool if I continue to run 12 quarts @ every oil change?

It should be. And I believe specs are actually 11... (http://dodgeram.org/tech/dsl/Facts/96specs.html)

I fill it with 12 each time myself. I have never liked hanging on to the last quart at every oil change so I always poured it in too.

This question was posted some time ago, and all the replies were "no worries, 12 quarts will not hurt"

Called my local Cummins repair shop and they said that 12.9 is capacity...

True?

Thanks for the help guys!

i would say running slightly less oil is better than more oil...take out a quart and a half or at least a quart

I've been running 12 qts in both my trucks for over 200k each-
