NOTE: This bulletin applies to vehicles within the following markets/countries: North
America, LATAM, APAC and EMEA.
NOTE: This bulletin applies to the listed vehicles above equipped with the 3.6L Pentastar
Upgrade Engines (Sales Codes ERC or ERG).
SYMPTOM/CONDITION:
The customer may describe that after an oil change they check their oil fill level and it is showing
overfilled on the oil dipstick.
DISCUSSION:
The 3.6L Pentastar Upgrade engine typically uses a smaller oil pan for most applications versus the
3.6L Pentastar Classic, resulting in an engine oil capacity of five (5) quarts for the Upgrade engine.
The 3.6L Pentastar Upgrade engine has a slower oil drain back rate. After filling the engine to the
correct oil capacity per specifications listed in the service information, the oil level may show low on
the oil dipstick due to the slower drain back rate. Engine crankcase overfilling can occur if not
enough time is allowed for the engine oil to drain back into the oil pan. DO NOT ADD MORE OIL
THAN SPECIFIED IN THE PUBLISHED SERVICE INFORMATION.
When identifying a 3.6L Pentastar Upgrade engine, the Upgrade engine has an EGR cooler
mounted to one of the cylinder heads, and a Variable Valve Lift (VVL) solenoid on the front of each
valve cover.
NOTE: There are currently a couple of exceptions to the above statement: 2016-to-Current
Jeep Grand Cherokee (WK) and Dodge Durango (WD), equipped with the 3.6L
Upgrade engine have a unique oil pan size and configuration that give them an
engine oil capacity of six (6) quarts.
