Specifications Engine oil To meet demands in Saab's extended service intervals all engines are filled with specially designed synthetic factory fill oils. Long service intervals, fuel economy and environmental issues are the base for our choice of oil. By using oils approved by Saab you minimise the tendencies for oil sludge build, by that protecting the engine from harmful, wear increasing, deposits. 273 Recommended oil viscosities Viscosity is a measurement of the oils thickness. The thickness influences, among other things, the fuel economy. For best function Saab recommends: For gasoline engines, SAE 0W-30 engine oil. Some oil companies have engine oils meeting our requirements (GM-LL-A-025) but with other viscosities than what we recommend as a first choice. Those engine oils are also accepted. Approved oils: All gasoline engines - Fully Synthetic Engine Oil fulfilling GM-LL-A-025 requirements. To ensure being able to take advantage of the Saab specified service intervals, be sure to select a fully synthetic engine oil fulfilling GM-LL-A-025 requirements. Extra engine oil additives Don't add anything to your oil. The recommended oils are all you will need for good engine performance and protection. Servicing/Oil changes: To be able to use recommended service intervals the need to use only approved engine oils is vital. Use only engine oils approved for your engine. Service should be done according to the recommended service intervals to optimize your engine's function through out its entire life. Saab Automobile AB will not take responsibility for any damage that might occur due to neglecting to meet above mentioned requirements. At your Saab dealers you can find Saab Genuine or Mobil engine oils. Among those there are oils specially designed to meet your engines specific needs. We recommend that you, with the help of our skilled service personnel, choose your oil from that selection. Other oil companies also have engine oils approved according to GM specifications. Oils meeting these standards may be identified as synthetic. However, not all synthetic oils will meet your engines requirements. You should only use oil that meets your engines specific requirements (GM-LL-A-025).
