What are the most important properties of oil to consider?

• Viscosity: Viscosity is a measure of the flowability of motor oil. Kinematic viscosity measures how quickly the oil flows under the influence of gravity. Dynamic viscosity describes how thick the oil is under shear stress. Higher viscosities mean the oil is thicker and flows more slowly, providing better protection at high temperatures and loads.
• Compatibility: The oil must be compatible with the materials in the engine and the seals to prevent chemical reactions that could cause leaks. Incompatibility can lead to significant engine damage and expensive repairs.
• Specifications and Certificates: Compliance with specifications and certificates ensures that the oil meets the required performance and protection standards. This ensures that the oil meets the manufacturer's requirements and the vehicle's operating conditions.
  
  

Which motor oil certifications exist?

Performance Levels: The classification of motor oils is based on internationally accepted standards, which are established through engine brake tests and laboratory oil tests. The most well-known standards are API, ACEA, JASO, and ILSAC. Motor oils for passenger cars are often classified as a combination for gasoline and diesel engines (e.g., ACEA A3/B4). The number after the letter describes the performance differences of the motor oils.

Manufacturer Approvals: Some vehicle manufacturers have additional requirements to the international classifications, known as manufacturer-specific standards. An oil type may work well in one engine but not in another. Therefore, vehicle manufacturers set their own requirements for lubricants (e.g., BMW Longlife-04, VW 504 00/507 00).

Which motor oil should I use for my car?

The correct motor oil depends on the vehicle type, engine, and manufacturer specifications. Consult the manual or manufacturer for the recommended viscosity and specification.

How often should I change the old oil?

Regular oil changes are important to extend the engine's life and ensure optimal performance. The oil change interval depends on the driving conditions and the type of oil used. Generally, it is recommended every 7,500 to 10,000 driven kilometers, but consult the manual for specific details.

What should I do with the old motor oil?

Proper disposal of used oil is crucial to avoid environmental pollution. Used motor oil should never be poured out or thrown in the trash as it heavily pollutes the environment. Bring it to a local collection point or workshop where it can be properly disposed of and recycled. Many car dealerships, municipal recycling centers, and gas stations also offer this service. Depending on municipal regulations, the amount of oil that can be dropped off may be limited to 5 to 20 liters.

Why is my motor oil black?

Black motor oil indicates normal wear and deposits. Excessive blackening may require an oil change or indicate other engine problems.

Can I mix different brands of motor oil?

It is not recommended to mix different brands or types of motor oil as this can affect performance. Use the same oil that is already in the engine.

How do I check my engine's oil level?

Check the oil level with the dipstick when the engine is cold. The oil level should be between the "Min" and "Max" marks.

What are vegetable oils?

Vegetable oils are lubricants derived from plants like rapeseed, soy, or sunflower. They are biodegradable and more environmentally friendly than mineral oils. In the automotive industry, they are used as additives or base oils to reduce internal friction in the engine. Vegetable oils contain a high proportion of unsaturated fatty acids, which help reduce internal friction. Despite their good lubricating properties, they are less common due to higher costs and limited temperature stability.

What types of coolants are there?

There are various types of coolants, including Organic Acid Technology (OAT), Hybrid-OAT, and silicate-free coolants. Use the coolant recommended by the vehicle manufacturer.
