Signs That Your Classic Car Needs an Oil Change

5 September 2024 by Tina Hill

Owning a classic car is a passion that comes with its own responsibilities, one of the most crucial being regular maintenance. Among the various maintenance tasks, keeping your classic car’s engine oil fresh is essential for ensuring its longevity and optimal performance. Unlike modern vehicles with advanced oil monitoring systems, classic cars rely on your vigilance to recognize when it’s time for an oil change. Here are some signs that your classic car needs an oil change.

Oil Pressure Warning Light

Many classic cars have an oil pressure warning light on the dashboard. If this light comes on, it often indicates that the oil pressure is low, possibly due to old, degraded oil or an oil leak. If the oil pressure warning light illuminates, it’s crucial to address it promptly. Check your oil level and condition, and if needed, change the oil and filter to ensure proper engine lubrication and performance.

Exhaust Smoke

Excessive smoke from the exhaust can indicate that your classic car’s engine oil is in poor condition. If the oil is old and degraded, it may not burn cleanly and can cause blue or gray smoke to emit from the exhaust. While exhaust smoke can also be caused by other issues, dirty or old oil is a common culprit. A timely oil change can help address this issue and improve the quality of your exhaust emissions.

Decreased Engine Performance

As oil ages, its lubricating properties diminish, leading to decreased engine performance. You may notice a decline in acceleration, reduced power, or an overall lack of responsiveness. If you’re experiencing these symptoms, it could be due to old oil no longer effectively protecting the engine. Changing the oil can help restore engine performance and ensure your classic car runs smoothly.

Increased Oil Consumption

If you need to add oil more frequently than usual, it may indicate that your current oil is breaking down or that your engine is burning oil. Classic cars often have higher oil consumption as they age, but if this becomes more frequent, it’s a sign that the oil needs changing. Regular oil changes can help manage oil consumption and maintain engine health.

Oil Smell Inside the Car

A burnt oil smell inside the car can indicate that your engine oil is overheating or burning. This smell often indicates that the oil is old and has lost its effectiveness. If you notice this odor inside the cabin, it’s a good idea to check the oil and consider an immediate change to prevent further issues.

Regular oil changes are essential for maintaining the performance and longevity of your classic car. By watching for these signs—dark or dirty oil, oil pressure warning lights, engine noise, exhaust smoke, decreased performance, increased oil consumption, and unusual smells—you can ensure that your classic car remains in top condition. Investing in timely oil changes protects your engine and helps preserve the value and enjoyment of your cherished vehicle. To learn more, contact an oil change provider, such as Scott's Wash & Lube.
