Engine Oil: Fluid Type Specifications
Engine Oil Type
Saab Turbo motor oil or motor oil to API SG and CCMC G4/G5 specification.
SAE 10W30 or 10W40. In markets where these viscosities are unobtainable 15W40 may be used instead, although not in winter. Use 5W30 or 5W40 oil
in climates with temperatures regularly below -20° C (-4° F). In climates with a constant temperature of +15° C or above, use 15W50 or 20W50 oil of
synthetic or synthetic-based type.
Important: The grades of oil recommended above contain all necessary additives and the use of additional additives should therefore be avoided.
