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 recom-
mend as a first choice. Those engine oils are also accepted.
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.
When to change engine oil.
Your vehicle has a display (SID) where time for service will be
shown. Based not only on mileage but also on driving condi-
tions the mileage at which a service will be indicated can vary
considerably.
Under normal circumstances the service indication will come on
at or around 15 000 miles or 2 years.
For this service system to work it is of outmost importance that
the right engine oil is used.
When the message for service is displayed you need to have
the required service done as soon as possible.
After the service your service personnel will reset the service in-
dicator. It is important to reset the service indicator in order to
optimize the time to the next service.
