⚑ QUICK DIY TIPS FOR THE 2018 JEEP WRANGLER
Torque your drain plug to 34 Nm (25 ft-lbs) to avoid leaks or stripped threads. Using the OEM filter (Mopar 68191349AC) is recommended for warranty compliance. Always use 0W-20 Full Synthetic as specified by Jeep — using the wrong viscosity can void your powertrain warranty. Check the maintenance schedule below for your next service interval.
