(8.5 l) 223 Engine oil 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 corresponding classes for diesel engines. The class designations for diesel engines begin with the letter "C" (Commercial). For example 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 lubrication, 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 additives.
