How much oil are you guys filling your engines with. Mine fit about 7 quarts before it showed ok on the dipstick.

I think I read somewhere the capacity is like 10 quarts but that would show overfill on my dipstick.

Input?

From the Cummins Shop Manual Spec Page
"B3.9 engine 9.5 Liters (10 qts)"

Mine also is supposed to be 10 qts. But I have an aux oil filter that is 1 qt capacity, 10 qts hits the full mark perfectly. So I guess without the filter, 9 qts.
