Engine oil is not just a service fluid – it is a key element that ensures engine longevity and reliability. Choosing the right engine oil has a direct effect on fuel consumption, exhaust emissions and overall vehicle performance. In this article we explain how to choose engine oil correctly, what to watch for, and why it is worth using SerwisUA in Wrocław.
Why is choosing the right engine oil so important?
Engine oil performs many important functions:
- It lubricates moving engine parts, reducing friction.
- It cools engine components by carrying heat away.
- It protects against corrosion and deposits.
- It seals the spaces between pistons and cylinders.
The wrong engine oil can lead to increased fuel consumption, a drop in engine power, and even serious mechanical damage.
Types of engine oil
- Mineral oil. Traditional oil obtained from refining crude oil. Recommended mainly for older vehicles with a simpler engine design.
- Semi-synthetic oil. A combination of mineral and synthetic oil. It offers better protection than mineral oil while remaining moderately priced.
- Synthetic oil. A high-quality oil produced chemically. It provides the best engine protection, especially in modern vehicles.
Engine oil viscosity grades
Engine oil viscosity describes its ability to flow at different temperatures. Markings such as 5W-30 or 10W-40 indicate oil viscosity at low and high temperatures. For example:
- 5W-30: works well at low temperatures, providing easy winter starting.
- 10W-40: better protection at higher temperatures, suitable for older engines.
Choosing the right viscosity grade depends on the vehicle manufacturer’s specification and operating conditions.
Engine oil standards and specifications
When choosing engine oil, pay attention to standards and specifications:
- API (American Petroleum Institute): defines oil quality standards.
- ACEA (Association des Constructeurs Européens d’Automobiles): European quality standards.
- Manufacturer specifications: e.g. VW 502.00, MB 229.5, BMW Longlife-04.
Make sure the oil you choose meets your vehicle’s requirements.
How often should engine oil be changed?
How often engine oil is changed depends on:
- The type of oil:
- Synthetic: every 15,000 – 20,000 km.
- Semi-synthetic: every 10,000 – 15,000 km.
- Mineral: every 5,000 – 10,000 km.
- Driving style:
- Frequent driving in traffic jams, short trips or dynamic driving can shorten change intervals.
Regular engine oil changes ensure engine longevity and reliability.
