If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals.
You can drive your vehicle in such a waythat may lead to higher oil consumptionincluding extended time at high enginespeeds, high loads, engine braking, hardcornering maneuvers, track and off-roadusage. Under these conditions, oilconsumption of approximately 1 quart per500 miles (1 liter per 800 km) is possible.Check the engine oil level at every refuelingand adjust to maintain proper levels toavoid engine damage.
You can also drive your vehicle in such away that dilutes and increases the level ofoil by frequent short trips that do not allowthe engine to get to operating temperature,extended idling and low speed driving forlong periods of time.
It is important to rely upon your dealershipto properly diagnose and repair yourvehicle.
We strongly recommend only using ourgenuine or our authorized re-manufacturedreplacement parts engineered for yourvehicle.
