Recommended oil grade

All cars are factory-filled with synthetic engine oil. These products contain components of extremely high quality to meet the demands placed by our engines.

Background

Synthetic engine oil has been chosen due to demands for increased service life and improved fuel economy to reduce environmental impact. Use of recommended oils prevents factors such as a tendency to build up coatings on the inside of the engine, which can block the lubrication system, increase wear and damage engine components.

Engine performance

Lubrication and viscosity are of the utmost importance when it comes to obtaining the best possible performance from our engines. It is therefore important that the oil recommendations are followed. The beneficial low-temperature flow properties of the oil enable it to quickly reach remote parts of the lubrication system, thereby reducing engine wear. In the same manner, oil viscosity at high temperatures has been adapted to provide the best function when used in extremely hot markets.

Fuel economy

Selecting oil with low viscosity has a positive impact on fuel economy. Problems with wear may arise, however, if the oil film becomes too thin due to low viscosity. The recommended oils maintain the right viscosity at various temperatures. The synthetic oil also generates lower fuel consumption during the warm-up period after start.

Durability

It is important that the oil's properties are maintained to their fullest during the entire change interval. Some oils' additives are consumed too quickly, resulting in internal, engine-damaging deposits and increased wear. The recommended oils meet today's high demands for durability provided that the service programme is followed.

An often neglected aspect is that more frequent oil changes are necessary if the car is driven often in urban traffic with frequent starts and short driving distances. This is because more fuel and condensation blends into the engine oil in such circumstances.

Environmental aspect

Lower fuel consumption leads to reduced emissions, especially carbon dioxide (CO2).

Service and oil change

It is important to follow the oil change intervals specified by the Saab service programme to guarantee the service life of all engine components and to keep engine performance optimised. Both distance driven and time between servicing are of the utmost importance. Servicing must be carried out when any of the criteria (service messages, distance driven or time) have been fulfilled.

Recommendation

Use oils as specified on the following tables as these oils fulfil the requirements specified above.

We strongly discourage the use of addition engine oil additives.

The risks of using oil that does not fulfil the specifications above are great. If an oil of too low a grade is used, there is a risk or wear due to poor lubrication or coatings in the engine due to prematurely aged oil that cannot keep the engine clean. This could eventually lead to clogged oil ducts and engine damage.
