Motor oils can be used all year round and provide excellent protection along with low oil consumption.
Motor oil additives
Older engines need motor oils that provide high lubrication and contain zinc additives. Our Classic motors oils ensure good lubrication, low wear, and lower oil consumption. Motor oils also keep your engine clean and protect it from corrosion.
Storing your vehicle over the winter?
A tip is to change the oil and warm up the engine before putting your vehicle into winter storage. New oil protects the engine better, even when the car is standing still.
High zinc additive
Zinc is added to lubricants as an organic bond between zinc and phosphorus called ZDDP (Zinc dialkyl dithiophosphate). The additive is a polar bond that provides multiple benefits in motor oil. With a high-zinc additive, the camshaft, lifters and rocker arms in overhead valve engines get additional protection.
Benefits of high-zinc additive
The ZDDP additive’s thin protective layer acts as a barrier against moisture and corrosion, and provides wear protection in the form of an additional layer of lubricating film, especially in areas where the oil film is thin due to operating conditions.
ZDDP also acts as an oxidation inhibitor. Oil oxidises as it ages because the oil molecules react chemically with the oxygen in the air. This process degrades the lubrication properties of the oil until it is necessary to change the oil. The zinc additives slow down the oxidation process and extend the service life of the oil. Other oil additives are also consumed continuously as an oil ages, referred to as additive depletion. This is another reason why oil must eventually be changed.
Frequently asked questions about classic motoroils
Can you mix Classic motor oils with other oils?
Classic motor oil should preferably not be mixed with a modern motor oil (mineral oil, full and semi-synthetic oils) since the oils have vastly different additives. Classic motor oil uses ZDDP and can have the opposite effect if mixed with a modern oil that has other additives, which can damage the engine.
What is a polar bond?
The term polar means that the substance has natural magnetic attraction to other polar substances and materials present in an engine, such as iron and other metals. This allows the ZDDP to migrate from the oil and attach to the metal surfaces of the engine where it creates a very thin protective layer.
