Porsche Classic Motoroil

Just in time for the start of the new year, Porsche Classic is launching motoroils for water-cooled four-cylinder and eight-cylinder engines and water-cooled six-cylinder engines to complement its existing motoroil for air-cooled four- and six-cylinder flat engines. And, as ever, the Porsche Classic label means a product made with Porsche Classic ingenuity.

The experts at Porsche Classic developed these motoroils with the help of engineers at the Porsche Development Center 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.

The engine is the heart of any Porsche. Even air-cooled flat engines pose specific challenges for lubricants. In short: Not every motoroil is suitable for the older flat engines. The process of developing a motoroil for classic air-cooled flat engines is therefore a balancing act between tradition and innovation: The oil must be as advanced as possible yet as traditional as necessary. Modern oils may be better from a technical perspective, but not always best suited to classic air-cooled flat engines.

Achieving the best lubricating and protective properties was a key consideration for the development of new motoroils for the water-cooled four-cylinder and eight-cylinder engines in Porsche transaxle models and the water-cooled six-cylinder engines in the 911 type 996 and the Porsche Boxster type 986. Given that not every classic car is used for everyday travel, these vehicles are often stationary for long periods and used only sporadically for short trips, making it more likely that engine components – particularly metals and sealing materials – may be damaged when they do interact. The special formulation of Porsche Classic Motoroils offers your classic car the ideal level of protection, even when the vehicle is not used for long periods.

Time for an oil change.

If you want to keep your Porsche classic car’s heart beating strongly for many more years to come, don’t forget to change the oil regularly. The oil change intervals for each vehicle and engine type can be found in the respective driver’s manual. Regardless of the number of miles covered, we recommend changing the motoroil once a year, particularly as short journeys can have a negative impact on the oil. Frequently starting a cold engine causes more fuel to enter the oil, generates combustion residues and allows the formation of condensation in the oil.

The first point of contact for an oil change is your Porsche Partner, where you can obtain the Porsche Classic Motoroil in a 1-liter, 5-liter or 20-liter can (10W-60). These and other Porsche Classic genuine parts are available from your Porsche Partner.

Porsche Classic Motoroils

20W-50 for 356, 914 and early 911 models
Porsche recommends the multigrade variant with a viscosity of 20W-50 for all 356, 914 and 911 models (up to 2.7 liters). When the engine is cold or warm, this oil is the best product for maintaining the classic engine, generates few deposits and offers good compatibility with the materials installed in the vehicle, such as cork gaskets or lead bearing shells.

20W-50, 1 liter – part no.: 00004320928
20W-50, 5 liter – part no.: 00004320929

10W-60 for 911 models with a displacement of 3.0 liters and above
Porsche recommends the variant with a viscosity of 10W-60 for 911 models with a displacement of 3.0 liters and above. Fully synthetic oil is suitable for the air-cooled, six-cylinder flat engines in 911 models with a displacement of 3.0 liters and above, and dry sump lubrication. These engines thus benefit from the technical progress in the development of motoroils.

The Porsche Classic Motoroil is the best product for maintaining the engine and keeping it clean – in both cold starting conditions and when the engine is warm under full load.
