Classic cars are not just a means of transportation, but also a real history on wheels. Keeping them in good condition is a task that requires special attention. One of the most important aspects of caring for a classic is choosing the right engine oil. In this article, we will look at why this is important and how to maintain your engine to keep it running smoothly.

Why choosing oil is so important

Classic car engines differ not only in design from modern cars, but also in maintenance requirements. Engines from the past often have more clearance between moving parts, and some use materials that require special protection. The wrong oil can accelerate wear on parts, lead to corrosion, or even damage the engine.

Three important reasons for a careful oil choice:

  1. Chemical composition: Modern oils often contain additives that may not be compatible with classic engines.
  1. Viscosity: Older engines require higher viscosity oils, mainly to compensate for wear.
  1. Additives: Oils containing zinc and phosphorus (ZDDP) are important for decelerated engines because they provide additional protection against wear.

Tips for choosing a motor oil

1- Determine your vehicle's requirements

Study the manufacturer's recommendations. If the original documentation is not available, contact clubs or experienced mechanics. They can tell you which oils are suitable for your model. For example, if you If you have a Volkswagen Polo, it is important to have an oil to choose one that meets the recommendations for that engine.

2. Choose oils with a high ZDDP content

Zinc and phosphorus provide an extra layer of protection, especially important for parts exposed to high pressure. Such oils are often labeled as “for classic cars”.

3. pay attention to the viscosity

For most older engines, oils with a viscosity of 20W-50 or 15W-40 are recommended. This helps to maintain stable lubrication, even at high temperatures.

4- Avoid synthetic oils

While synthetic oils are excellent for modern cars, in classic engines they can be the cause of leaks due to incompatibility with seals.

How often to change oil

The frequency of oil changes for a classic car depends on the mileage and the conditions of use. If you rarely drive your classic car, it is advisable to change the oil at least once a year, even if the car is in a garage. If you travel regularly, you should change the oil every 3000 to 5000 kilometers.

Tips for changing the oil

  1. Warm up the engine before changing the oil so that it becomes less thick and drains more easily.
  1. Only use quality filters that are suitable for your model.
  1. After changing the oil, check the oil level and check for leaks. Regularly checking the oil level helps prevent unexpected engine problems.
  2. After changing the oil, regularly note the date and mileage.

Keep your bike real and running

Proper engine maintenance is essential for a long and reliable life of your car. Remember that when choosing oil, you should consider the age, condition and construction of the engine. If you still have questions, consult experts or clubs that focus on your car brand. The right oil will not only extend the life of the engine, but also maintain its authenticity, which is important for true classic car enthusiasts.
