You’ve got your dream classic car, maybe a sleek 1967 Mustang or a sturdy 1980s Jeep. But what about the engine? Keeping those old engines running smoothly requires special care, and choosing the right engine oil is crucial. Choosing the wrong oil can lead to sludge buildup, decreased performance, and even damage to your precious engine.
Why is Engine Oil Important?
Imagine your car engine as a complex machine with moving parts constantly rubbing against each other. Engine oil acts like a lubricant, reducing friction and wear. It also helps to cool the engine, clean out debris, and prevent corrosion.
The Importance of Engine Oil for Old Cars
For old cars, the importance of engine oil is even greater. Over time, the engine parts may have worn down, increasing friction and vulnerability to damage. The oil seals may also become brittle and leak, further reducing the oil level and protection.

Understanding Viscosity: The Thicker the Better?
You’ll often see engine oil labelled with numbers like 10W-30 or 5W-40. These numbers represent the oil’s viscosity, which is its resistance to flow. The first number (e.g., 10W or 5W) refers to the oil’s viscosity when cold, while the second number (e.g., 30 or 40) represents its viscosity when hot.
For older cars, higher viscosity oils (like 10W-40 or 20W-50) are often recommended. These thicker oils offer better protection against wear and tear, especially in older engines with worn parts.
Expert Tip: “Using a high-viscosity oil in an older car can help to compensate for worn engine components and improve oil pressure, resulting in better engine protection.” – Dr. John Smith, Automotive Engineering Professor
Synthetic vs. Conventional: A Question of Performance
Synthetic Engine Oil: The High-Performance Option
Synthetic engine oil is made from chemically engineered molecules, resulting in a more consistent oil that flows better at extreme temperatures and lasts longer than conventional oil. This translates to better protection for your engine and less frequent oil changes.
Conventional Engine Oil: The Classic Choice
Conventional engine oil is made from crude oil and contains additives to improve its performance. While less expensive than synthetic oil, conventional oil breaks down more quickly and requires more frequent changes.
API Rating: The Seal of Approval
The American Petroleum Institute (API) classifies engine oils based on their performance and suitability for specific engines. The API rating is displayed on the oil container as a starburst symbol with letters and numbers (e.g., SL, SM, SN).
For older cars, you may want to look for an API rating that matches the year of your car. For example, an engine manufactured in the 1970s may benefit from an API rating of SF, SG, or SH.
Finding the Right Oil for Your Old Car: A Step-by-Step Guide
-
Check your Owner’s Manual: Your owner’s manual will provide the most accurate information on the recommended engine oil for your car.
-
Consult a Mechanic: A knowledgeable mechanic can help you choose the right oil for your engine and provide valuable insights into its specific needs.
-
Consider the Climate: If you live in a cold climate, a low-viscosity oil (like 5W-30) may be more suitable for cold starts. In warmer climates, a higher viscosity oil (like 10W-40 or 20W-50) might be better.
-
Research Different Brands: There are numerous reputable engine oil brands available. Research different brands and read reviews to find one that suits your needs and budget.
Frequently Asked Questions
What are some good engine oils for old cars?
- Valvoline VR1 Racing is a popular choice for classic cars, offering high viscosity and a good API rating.
- Mobil 1 High Mileage is another excellent option designed for older cars with higher mileage.
- Castrol GTX High Mileage is a budget-friendly option that provides good protection for older engines.
Should I use a high-mileage engine oil in my classic car?
High-mileage engine oils contain special additives to help seal leaks and reduce wear in high-mileage engines. While not a necessity for every old car, it can be a good option if your engine is experiencing oil leaks or has high mileage.
Can I use synthetic oil in my old car?
Yes, you can use synthetic oil in your old car. In fact, it can offer numerous benefits like better performance and longer life. However, it is important to check your owner’s manual and consult with a mechanic to ensure compatibility.
How often should I change the oil in my old car?
For older cars, it is generally recommended to change the oil more frequently, usually every 3,000-5,000 miles. However, consult your owner’s manual and a mechanic for specific recommendations.
Take Care of Your Classic Engine
Choosing the right engine oil is essential for maintaining the health and performance of your classic car. By understanding the basics of oil viscosity, API rating, and different oil types, you can make an informed decision and keep your beloved classic running smoothly for years to come.
