How To Choose the Right Engine Oil for Your Car

For many drivers over 55, car care is about more than performance. It is about reliability, safety, and protecting an investment. Whether you’re planning road trips, running errands, or helping family members get around, understanding how to choose the right oil matters. Knowing how to choose the right engine oil for your car doesn’t have to be complicated, but a few key details can make a big difference.

Start With Your Owner’s Manual

Your owner’s manual should be your first reference point. It outlines the correct oil grade for your vehicle, including viscosity ratings like 5W-30 or 10W-40, and indicates whether the engine requires synthetic or conventional oil for proper performance.

Viscosity refers to how thick the oil is and how it flows at different temperatures. Using the wrong viscosity can reduce fuel efficiency and increase engine wear — especially in older vehicles.

If your car has higher mileage, the manual may also recommend high-mileage oil blends designed to reduce leaks and protect aging engine components.

Understand the Types of Motor Oil

There are three main types of oil to consider:

Conventional Oil

Typically less expensive and suitable for many older vehicles. It works well if you follow a consistent oil change schedule.

Synthetic Oil

Offers better protection in extreme temperatures and may last longer between changes. It’s often recommended for newer engines or vehicles that endure stop-and-go traffic.

High-Mileage Oil

Formulated for cars with 75,000 miles or more. These blends help condition seals and reduce oil burn-off, making them a practical option for many older drivers.

Knowing how to choose the right engine oil for your car often comes down to vehicle age, driving habits, and budget.

Pay Attention To Driving Habits

Short trips, extended idling, and infrequent driving can all impact oil performance. Many retirees drive less than they once did, so they should schedule oil changes based on time rather than mileage.

Skipping regular maintenance can lead to avoidable engine damage. In fact, common oil-change mistakes, such as overfilling, using the wrong filter, or delaying service, can reduce engine life.

When in Doubt, Ask a Professional

If oil labels feel confusing, a trusted mechanic can help clarify what your vehicle needs. Bringing your owner’s manual to an appointment ensures accurate service.

A little knowledge goes a long way. By understanding viscosity ratings, oil types, and your own driving patterns, you can keep your vehicle running smoothly for years to come.
