Gas (incl. performance models)
Gas Grand Cherokee engines range from older inline and V6 options to V8 HEMI and high-output SRT8/Trackhawk variants, so service needs can differ by a wide margin. Oil service intervals can vary widely across the lineup, so follow the schedule shown for your specific engine and year rather than relying on a single number. Keep up with air filtration and ignition-related maintenance because misfires and poor combustion control are more noticeable under load in larger displacement engines. Examples in this family include the 3.6 V6, 5.7 V8 HEMI, SRT8 6.4 V8, and 6.2 V8 Trackhawk.
