Mario Vester, Engen Product Manager: Automotive, gives advice on how to get more efficiency, performance and value from your car as fuel prices continue to rise.

For years, most South African drivers have treated engine oil as a basic commodity. Top it up, change it occasionally, move on. “Oil is oil,” right? Not anymore.

With fuel prices climbing, lubricants are playing a far more important role. They’re no longer just about protecting your engine, they directly influence fuel efficiency, performance and long-term running costs.

What sits inside that bottle is more advanced than many realise. Modern lubricants are carefully engineered blends of base oils and additives designed to reduce friction, manage heat and keep engines clean. In simple terms, the right oil helps your car run more efficiently which matters when every litre counts.

Efficiency starts under the bonnet

Today’s engines, especially smaller turbocharged petrol units and modern diesels, operate under higher stress. They rely on precise lubrication to perform properly.

Using the wrong oil or simply choosing the cheapest option can increase friction, forcing the engine to work harder and burn more fuel. It can also lead to faster wear and more frequent maintenance.

Even small gains matter. A 1–3% improvement in fuel efficiency may seem minor, but over time it adds up, particularly at current fuel prices.

South African conditions add pressure

Local driving conditions make things tougher. Heat, dust, traffic and long distances all put extra strain on engines.

Whether you’re commuting daily or heading out on road trips, the right oil helps maintain performance, protect components and reduce the risk of breakdowns. It can also extend service intervals, saving time and money.

A smarter choice for modern cars

As engines evolve, so do lubricant requirements. Manufacturers are increasingly specifying lower-viscosity, high-performance oils to improve efficiency and reduce emissions. That’s where products like Engen Xtreme come in. Designed for modern engines, they help improve fuel economy, protect critical parts and perform under demanding conditions.

The takeaway

Engine oil is no longer just a maintenance item it’s part of how your car delivers efficiency and value.

In a world of rising fuel costs, choosing the right lubricant is one of the simplest ways to keep your car running better, for longer, while saving money where it matters most: at the pump.
