• Beating friction
Without oil, the surfaces inside your engine which rub together will heat, fuse and quickly cause engine seizure. Oil, and its special additives, forms a molecular barrier between moving parts, to stop wear and minimise heat build-up.
• Cooling hot spots
Oil cools parts that the engine's water-based coolant cannot reach, bathing the combustion chamber and pistons, where temperatures may exceed 1000°C. The oil assists in transferring the heat to the engine cooling system. Heat in the oil is also lost by air flow over the sump, and via any auxiliary oil cooler.
• Cleaning the inner engine
Oil washes away combustion by-products (mainly carbon) on pistons and cylinders, transporting them to the oil filter, and holding the smallest particles in suspension until they are flushed out by an oil change. Duckhams oils undergo extensive tests in the laboratory, and on the road.
Note: It is antisocial and illegal to dump oil down the drain. To find the location of your local oil recycling bank, call this number free.
Engine oil types
Mineral oils are the "traditional" oils, generally suited to older engines and cars not used in harsh conditions. Duckhams Hypergrade Plus and Hypergrade are well suited for use in most popular family cars. Diesel oils such as Duckhams Diesel are specially formulated for Diesel engines, including turbocharged models and 4x4s. Synthetic oils are the state-of-the-art in lubricants, offering ultimate protection, but at a fairly high price. One such is Duckhams QS, for use in ultra-high performance engines. Semi-synthetic oils offer high performance engine protection, but at less cost than full synthetic oils. Duckhams QXR is an ideal choice for hot hatches and hard-driven cars.
