Ram Trucks 2014 ProMaster Commercial - Diesel Supplement - Manual (Page 89)

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
only when the level on the dipstick is below the mini-
mum notch. The total capacity from the minimum notch
to the maximum notch is 1.7 qts (1.6L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE: It is possible for your oil level to be slightly higher
than a previous check. This would be due to diesel fuel that
may temporarily be in the crankcase due to operation of the
diesel particulate filter regeneration strategy. This fuel will
evaporate out under normal operation.
Never operate the engine with oil level below the mini-
mum notch or above the upper maximum notch.

CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
