FAQ

Asked Questions

What is the role of engine lubricant?

Engine oil reduces friction between the moving parts of the engine, helps cool the engine, removes deposits, and protects against wear.

How often should I change the oil?

It depends on the type of oil (mineral, semi-synthetic, or fully synthetic), your driving habits, and operating conditions (e.g., high heat). Some synthetic oils can last longer if recommended.

What is the difference between mineral and synthetic oil?

Mineral (conventional) oil is cheaper but requires more frequent changes.
Fully or semi-synthetic oils have additives that improve stability in hot climates and provide better engine protection.

How do I choose the right viscosity?

Refer to your vehicle’s manual. Viscosity is classified by the SAE rating (like “5W-30”): the first number (before „W“) indicates cold-start performance, and the second number indicates performance at high temperature.

Can I mix different types of oil?

It is not recommended to mix oils with different base formulations, as this may reduce the lubrication efficiency and harm the engine.

Do lubricants have an expiration date?

Yes, oils may degrade over time, especially after opening the container. Some oils have a shelf life of several years before they perform optimally.

How do I read the specifications on the oil label?

Viscosity grade (e.g., SAE)

Performance specifications such as API or ACEA to ensure compatibility with your engine.

Oil type (mineral, semi-synthetic, or synthetic) to understand its performance and suitability.

What additives are in the oil?

Oils often contain additives like anti-wear agents, detergents, and viscosity stabilizers, which enhance performance and protection.

How should I dispose of used oil?

Used oil should be taken to recycling centers or authorized workshops for safe disposal, because it can be environmentally hazardous.

What are the benefits of using high-quality oil?

Better protection against engine wear

Stable performance under extreme temperature conditions

Potential for reduced fuel consumption if the right oil is used

Longer engine life with proper maintenance
