Excessive Oil Loss or Consumption

^ External oil leaks. Tighten bolts and/or replace gaskets and seals as necessary.

^ Improper reading of dipstick. Check oil with vehicle on a level surface and allow adequate drain-down time.

^ Continuous high speed driving and/or severe usage such as trailer hauling, will decrease oil mileage.

^ PCV valve malfunctioning.

^ Valve guides and/or valve stem seals worn or omitted. Ream guides and install oversize service valves and/or new valve stem seals.

^ Improper oil viscosity. Use recommended S.A.E. viscosity for prevailing temperatures.

^ Piston rings broken, worn, or not seated. Allow adequate time for rings to seat. Replace broken or worn rings as necessary.

^ Piston improperly installed or misfitted.
