For all year round filling (oil change intervals 15.000 miles/24.000 km) use multi-grade oils
SAE 10 W-40, SAE 15 W-50 or 20 W-50. The 20 W-50 oil should not be used at constant
temperatures below + 5° F/- 15° C.
Porsche recommends the use of single-grade oils only if multi-grade oils are not readily
available. Oil changes must then be performed according to season to guard against engine
damage. The following viscosity can be used: in summer SAE 30, in winter SAE 20 W
(only at constant temperatures below + 41 ° F / + 5° C).
Porsche does not recommend the use of oil additives.
