Engine oil
Oil recommendation:
We recommend the use of Saab or Mobil oils, available
from you Saab dealer, for regular oil changes.
These oils ful-
fill Saab’s requirements as wells as the most stringent require-
ments set by API and ACEA classifications.
Basic recommendations for Saab 9-3 petrol engines
• SAE 5W-30 or 5W-40.
The oil should be semi or fully synthetic and fulfill grade re-
quirements for ACEA A3/B3, API SJ or higher. In addition to API
and ACEA the ILSAC GF-3 specification is approved for use in
applicable markets.
Fully synthetic oils with viscosity’s 0W-40/50 of well known
brands and fulfilling minimum ACEA A3/B3 are also recom-
mended, especially for extreme driving conditions.
Oils that fulfil GM-LL-A 025 requirements for gasoline engines
can also be used.
Oil specification
Oil for gasoline engines is classified by the API (American Pe-
troleum Institute) and ACEA (European Automobile Manufac-
turers Associations) standards.
According to the API standard, engine oils are graded using an
alphabetical system with the grade classes SJ (since 1996) and
SL (since 2001). The demands of the SL class are most strin-
gent.
Under ACEA nomenclature, oils are divided into Class A for
petrol engines and Class B for diesel-engined passenger cars.
Class A, for petrol engine oils, is divided into three grades (A1,
A2 and A3) where grades A2 and A3 normally encompass semi
and fully-synthetic oils.
