Engine oil plays one of the most critical roles in keeping a vehicle running safely and efficiently. Beyond simply lubricating moving parts, oil reduces friction, manages heat, removes contaminants and protects the engine’s internal components from wear over time. Yet it remains one of the things that drivers may be tempted to delay changing or save a buck on.
The first essential is always use the correct oil grade and type for your specific vehicle. The CEO of MasterDrive, Eugene Herbert, expands: “Manufacturers design engines to work optimally with a particular viscosity and formulation.
“This specification is carefully matched to the engine’s tolerances, operating temperature range and mechanical design. Using the right oil allows the engine to maintain proper lubrication under varying conditions, from cold starts to sustained highway driving.”
When drivers use the wrong oil, or neglect oil changes altogether, several issues can develop. “Incorrect viscosity can lead to inadequate lubrication, causing increased friction between moving parts. Over time, this accelerates wear on critical components such as the camshaft and bearings.
“Old or degraded oil also loses its ability to carry away heat and trap contaminants, which can result in sludge buildup, reduced fuel efficiency and, in severe cases, engine failure. In turbocharged vehicles, insufficient or degraded oil can cause the turbo’s high-speed shaft to overheat rapidly, leading to premature turbocharger failure.”
These mechanical consequences carry direct safety implications for drivers. “A well-maintained engine responds predictably under acceleration, braking and emergency manoeuvres. An engine suffering from oil related wear may experience reduced power delivery, unexpected stalling or overheating, all of which can compromise a driver’s ability to react safely in traffic.
“Vehicles used for daily commuting, especially over long distances or in heavy congestion, cannot be safely driven without a properly lubricated and, consequently, well-functioning engine. A vehicle that stalls unexpectedly in traffic not only increases a driver’s personal safety but also creates a hazard for other motorists, particularly on highways where a sudden loss of power increases the risk of a collision.”
Regular maintenance should be treated as a non-negotiable part of responsible vehicle ownership. “Many drivers only think about their engine when something goes wrong. Consistent oil changes and general servicing is a simple way to protect both the vehicle and the safety of all road users.
“Skipping or delaying maintenance increases the likelihood of costly repairs and unplanned breakdowns and, importantly, being stranded in unsafe situations. Following a manufacturer’s recommended service schedule identifies small issues early, before they escalate into major and potentially dangerous mechanical failures.”
Ultimately, engine oil is far more than a routine fluid top up. “It is a foundational element of vehicle health that directly influences performance, longevity and driver safety. Regular and correct maintenance is an investment worth prioritising,” says Herbert.
