SB22-J-002A
SERVICE BULLETIN - THE PURPOSE OF THIS BULLETIN IS TO DESCRIBE DIFFERENT INSTANCES WHERE OIL CONSUMPTION OCCURS AND TO MAKE AVAILABLE A WORKSHEET TO ASSIST THE TECHNICIAN IN DETERMINING IF OIL CONSUMPTION IS EXCESSIVE. OIL USAGE HAS A DIRECT RELATIONSHIP WITH THE AMOUNT OF FUEL USED. THE HARDER AN ENGINE WORKS, THE MORE FUEL AND OIL IT WILL USE. THEREFORE, OIL USAGE AS A FACTOR OF FUEL USAGE IS A MORE ACCURATE INDICATOR OF ACCEPTABLE OIL CONSUMPTION. THE ACCEPTED RATE OF OIL CONSUMPTION FOR THE AFFECTED VEHICLES IN THIS BULLETIN IS 0.946 LITER (1 QT) WITHIN 379 LITERS (100 GALLONS) OF FUEL USED. THIS RATE ONLY APPLIES TO VEHICLES UNDER WARRANTY, MAINTAINED IN ACCORDANCE WITH THE APPROPRIATE MAINTENANCE SCHEDULE, DRIVEN AT LEGAL SPEEDS AND WITHIN DESIGN INTENT OF THE VEHICLE. MANY FACTORS CAN AFFECT AN OWNER'S CONCERN WITH OIL CONSUMPTION. DRIVING HABITS AND VEHICLE MAINTENANCE VARY FROM OWNER TO OWNER. THOROUGHLY EVALUATE EACH CASE BEFORE DECIDING WHETHER THE VEHICLE IN QUESTION HAS ABNORMAL ENGINE OIL CONSUMPTION.
