Frequently asked questions
Operating under intense conditions, the primary role of commercial vehicle oil is lubrication, reducing the friction and wear on moving engine parts, for example between the cylinder walls and piston rings, or the camshaft lobes and followers. Oil also acts as a coolant, absorbing and transferring the huge amounts of heat produced in the engine combustion chambers and piston under-crown area, helping prevent overheating. The oil also acts as a sealant in the space between the piston ring and cylinder wall to prevent combustion pressure (engine power) from escaping. It has detergent qualities too, preventing waste matter resulting from combustion and impurities from sticking to the engine interior, keeping it cleaner. Finally, as a rust inhibitor it neutralises acids produced by combustion gases, preventing rusting and corrosion.
Commerical vehicle engines are constantly evolving, with ever-improving performance and fuel efficiency – but this relies on the quality of your engine oil. Our lubricants have been engineered to respond to the incredible pressures and temperatures truck engines generate, allowing your vehicle to maintain its optimal performance for longer.
You should change your truck's oil and filter at or before the end of the oil-change intervals indicated by your vehicle manufacturer. These are based on distance travelled or time. Regularly changing the oil helps keep your engine oil in good condition and provides the best protection for all your engine components.
There are many engine oils on the market for trucks, each with a range of grades eg 5W-20, 5W-30 etc – these enable owners to match the right oil with the specific requirements of their truck’s engine. Your vehicle’s handbook will give you a minimum oil specification, however, our Lube Recommender tool provides a bespoke recommendation for ALL your truck’s specific lubricant and fluids needs, from the engine and transmission to the differential, cooling system and brakes – ensuring your vehicle keeps performing at its peak.
Commercial vehicle oil can be mineral-based or synthetic. Mineral oils are generally suited to older trucks and are usually less expensive than synthetic oils, which are modified to improve their protective and lubricant properties so they can perform in more advanced engines.
