The importance of supplying the right oil

Simon Matthews, product development manager at Exol Lubricants, is keen to emphasise the importance of raising awareness about selecting the right oils and lubricants for the colder months. He also highlights how advancements in lubrication technology are helping engines endure harsh winter conditions.

Lubricants are often referred to as the ‘lifeblood’ of an engine, playing a crucial role in protecting, cooling and lubricating moving parts. Just as a blood supply is vital to the body, the right oil is essential for the health of an engine.

Exol is urging you to reiterate that using the wrong type or viscosity of oil may not cause an immediate failure, but it will gradually erode the protection recommended by the OEM. This could lead to long-term damage – and higher future costs of repair.

When temperatures are low, the performance of lubricants becomes even more critical. When an engine is started in cold weather, the oil must flow immediately from the sump to all engine components to prevent wear, particularly in areas under heavy load.

OEM recommendations are tailored to specific climates, meaning the right oil can make the difference between optimal performance and potential damage; for example, if a vehicle requires a 0W-20 oil but is instead filled with a 15W-40, the oil flow will be significantly compromised at low temperatures, increasing the risk of engine wear.

Engine lubrication has evolved significantly since the days of the first automobiles. Modern engines are high-revving, high-torque machines that demand precise lubrication.

Unlike older engines that relied heavily on boundary lubrication, today’s engines depend on oils to act as carriers between surfaces, providing chemical lubrication at critical points of contact.
