Oil grade:
We recommend the use of oils that are available from your
Saab dealer, for the regular oil changes.
These oils fulfill the most stringent requirements set by API and
ACEA classifications.
Oil for gasoline engines is classified by the API standards
(American Petroleum Institute) into the grade classes SH (since
1993) and SJ (since 1996). The SJ class fulfils more stringent
requirements and has a lower phosphorous level.
These grade classes are most often combined with the corre-
sponding classes for diesel engines. The class designations for
diesel engines begin with the letter “C“ (Commercial). For ex-
ample a grade combination suitable for both types of engine
could be API SH/CD or SJ/CF.
Under ACEA nomenclature, oils are divided into Class A for
gasoline engines and Class B for diesel-engined passenger
cars. There is a further class for heavy diesel engines. Each
class is divided into three grades: 1, 2 and 3, where grades 2
and 3 normally encompass semi and fully-synthetic oils.
In the same way as in the API system, gasoline and diesel
engine specifications are combined for products that can be
used in both types of engine. For example, a grade designation
could be ACEA A2/B2 or ACEA A3/B3.
To afford Saab engines the best protection, with regard to lubri-
cation, the ability to dissolve residues and the neutralization of
combustion products, we recommend the following oil grades:
• API SH/CD/CF or SJ/CD/CF.
• ACEA A2/B2 or A3/B3.
These oils contain the additives required for the engine to
function well. We advise against the use of further addi-
tives.
