oil level JEEP WRANGLER JK 2019 Owners Manual

Checking Oil Level
To ensure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding 1 quart (0.95 liters) of oil when the reading is at the
bottom of the crosshatch zone will result in a reading at the
top of the crosshatch zone on these engines.
