With financial pressures mounting, purchasing a new car has become an unaffordable luxury for many. However, the expiration of your car’s three- or five-year warranty does not necessitate an immediate replacement, especially if your vehicle has been well maintained and remains in good working condition. Instead, choosing the right engine oil can help keep your car in excellent shape.
As of June 2022, data from Lightstone revealed that the average age of vehicles on South African roads was 10.5 years, up from 9.3 years in 2015. Maintaining an older car can be costly, as mechanical breakdowns and maintenance expenses become the owner’s responsibility once the warranty expires. Although modern cars are built to higher standards than those 30 years ago, their complex electronics can lead to expensive repairs when issues arise.
The Role of Engine Oil in Vehicle Maintenance
To prolong the life of your engine, using the correct oil is crucial. Not all engine oils are created equal.
Functions of Engine Oil:
- Reduce Friction and Wear: Engine oil’s primary function is to minimize friction and wear within the engine.
- Prevent Sludge and Varnish Formation: It helps prevent sludge and varnish from forming on metal surfaces.
- Improve Fuel Economy: Engine oil can enhance fuel efficiency.
- Maintain Optimum Engine Conditions: It keeps the engine running smoothly.
- Protect Seals: Engine oil prevents seals from leaking or cracking.
- Reduce Foaming: It helps reduce foaming as oil moves through the engine.
- Engine oils consist of base oil and additional materials such as additives, detergents, and viscosity modifiers. The right balance of these components is essential for achieving the desired performance attributes for your vehicle. The type of base oil (mineral vs. synthetic) and its viscosity depend on the vehicle’s requirements and the Original Equipment Manufacturer (OEM) specifications.
