OIL CONSUMPTION WILL BE HIGHER THAN NORMAL AND CONSISTENT, IF THIS WEAR OCCURS, THE CONDITION REMAINS UNTIL REPAIR. UNUSUAL SWINGS OR VARIATIONS IN OIL CONSUMPTION ARE NOT CONSISTENT WITH THIS CONDITION AND MAY BE THE RESULT OF VEHICLE USAGE RATHER THAN THE CONDITION DESCRIBED HERE. ADDITIONAL INFORMATION IS SUPPLIED IN THIS BULLETIN TO ASSIST IN THE ASSESSMENT AND DETERMINATION IF VEHICLE USAGE IS A REASON FOR THIS VARIED OIL CONSUMPTION."
