290 Technical dataEngine oilTo meet demands in Saab's extended service intervals all en-
gines 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 minimize the tendencies for oil sludge build, by that
protecting the engine from harmful, wear increasing, deposits.
Approved oils
For all gasoline engines - synthetic engine oil - approved
against the GM-LL-A-025 specification. To benefit from Saab´s
specified service intervals, pleasure ensure to select a synthetic
engine oil approved against GM-LL-A-025.
For optimum performance Saab recommends the use of Saab
Long Life Turbo Oil SAE 0W-30, 0W-40, 5W-30 or 5W-40.
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 ap-
proved 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 ne-
glecting to meet above mentioned requirements.
At your Saab dealers you can find Saab and GM Genuine en-
gine 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 offer engine oils approved against GM
specifications. Oils meeting these standards may be marked as
synthetic. However, not all synthetic engine oils will meet your
engines specific requirements. Please ensure only to use syn-
thetic oils approved against your engines specific requirements,
i.e. GM-LL-A-025.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.
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.

For optimum performance Saab recom-
mends:Gasoline engines –
AON 90.
Gasoline with a lower octane rating can be used, although not
lower than AON 87. However, engine performance will fall slightly
and heavy loading and laboring should be avoided. For optimum
performance, use the recommended grade of fuel.
