Motorsport principles are also applied to the engine’s oil supply. Continued lubrication is vital, especially at very high engine speeds of up to 9,000 rpm and under the effects of the particularly high lateral and longitudinal acceleration that can be experienced on the racetrack.
Seven scavenge pumps in total return the engine oil quickly and efficiently to the external oil tank. Together with a new oil pressure pump offering fully variable displacement, optimum oil pressure is assured in all operating conditions. This system provides reliable lubrication of hard-working components and increases the robustness of the engine under heavy use on the racetrack.
Also new is the particularly efficient supply of oil to the heavily loaded connecting rod bearings. This is realised by a central oil feed into the crankshaft. Another innovation sees the oil efficiently defoamed by a centrifuge before it is delivered to the separate oil tank. This engineering solution originates from high-performance motorsport and is also used in the
The new 911 GT3 is factory-filled with Mobil 1 fully synthetic high-performance engine oil. The excellent lubrication properties of this oil ensure a reliable cold start, even at very low temperatures, and contribute not least to the durability of the engine.
