FSM Maintenance Protocol & Warnings
⚠️ CRITICAL WARNING (OIL CONSUMPTION): The 3.8L V6 is notorious for excessive oil consumption between changes. Jeep technically considers burning 1 quart per 1,000 miles “acceptable” for this engine. You MUST check your dipstick every 1,000 miles to prevent running the engine dry and spinning a rod bearing.
