At Kenny Fuels, we understand the importance of using the right oil to keep your engine running smoothly and efficiently. That’s why we offer a wide selection of high-quality Castrol and Q8 engine oils, suitable for a variety of vehicles.


What Does Engine Oil Do?

Engine oil plays a vital role in keeping your vehicle’s engine running smoothly and efficiently. Here are its key functions:


Lubrication: This is the primary function of engine oil. It forms a thin, slippery film between moving parts within the engine. This film reduces friction, minimising wear and tear on the engine components and prevents them from seizing up. Without proper lubrication, the engine would quickly grind itself to a halt.


Cooling: The engine generates significant heat during operation due to combustion and friction. Engine oil acts as a coolant, absorbing this heat and carrying it away from critical engine components. This helps maintain a safe operating temperature and prevent overheating, which can cause engine damage.


Cleaning: As the engine runs, it naturally creates contaminants like combustion byproducts and microscopic metal particles. Engine oil helps suspend and carry these contaminants to the oil filter, where they are trapped and removed from circulation. This helps prevent the buildup of sludge and debris within the engine, which can impair performance and lead to premature wear.


Corrosion Protection: Engine oil contains special anti-corrosion additives that help protect metal components from rust and other forms of corrosion. These additives form a protective barrier on metal surfaces, preventing them from coming into direct contact with moisture and other corrosive elements that can cause damage.


Sealing: Engine oil plays a role in maintaining proper engine compression by helping to seal the gaps between pistons and cylinder walls. This ensures that the combustion process happens efficiently and prevents power loss.


In summary, engine oil acts as a multi-functional lubricant, coolant, cleaner, and corrosion inhibitor, all essential for keeping your engine running smoothly and reliably for a long time.

FAQs About Engine Oil

What does engine oil do?

Engine oil plays a vital role in keeping your vehicle’s engine running smoothly and efficiently. It helps to lubricate, cool, clean and protect your engine.


Does a tractor need engine oil?

Absolutely, tractors do need engine oil. Just like any other internal combustion engine, a tractor’s engine relies on engine oil to function properly.


What does the ‘W’ mean in engine oil?

The ‘W’ stands for the word ‘Winter’, and it is a measurement of the ‘viscosity’ of the engine oil and its ability to meet temperature demands. As a quick example, our 1000-litre Castrol Vectron 15w/40 – the ‘15w/40’ is the viscosity rating for the engine oil – The smaller the number, the better it will flow. A 5W-30 will flow easier than a 10W-30 at start-up temperatures and a 10W-30 will flow more easily than a 10W-40 at normal engine operating temperatures.
