Porsche Classic Motoroil – FAQ and Lexicon

The experts at Porsche Classic developed these engine oils with the help of engineers at the Porsche Development Centre in Weissach and a German oil supplier, formulating them especially for the requirements of flat engines in 356 and 911 models (including the type 996), all four-cylinder and eight-cylinder engines, such as those in the 924, 928, 944 and 968, as well as the Porsche Boxster type 986. During development, the oil was subject to extensive laboratory and field tests designed to check its running performance and lubrication properties. Porsche Classic Motoroil is available in four different variants: 20W-50, 10W-60, 10W-50 and 5W-50.
