Ratings and reviews
Best oil, i use it in my M4 5w40. I drive the car on insane level. Oil change every 5000 km.
0W-20 is generally expensive but this brand is good and made in Germany.
The character of my car has changed immediately as soon as l started the engine.This oil is quite different from other synthetic oils.More silent engine,and hotter engine...etc.From now on Kroon Oil will be my cars best friend.????
Got this one for an engine flush as it’s a decent brand and price is super good
This might be one of the best oils for the price ive ever tested, no more ticking, perfect lubrication from start, after 10.000kms the oil came brown and left the inside of the engine cleaner than when it entered. VERY GOOD OIL
Castrol good oil quality and and the oil prescribed by Volvo for the S60 2.5t
Very good quality oil, recommended by Mini Cooper as i read somewhere, it has all BMW requirements.
Its really nice to be able to buy same oil the dealerships use, and most interesting part is that it is suprisingly affordable!

Which oil for my car? Types, classifications, and tips for choosing
Motor oil is a technical liquid in the car engine lubricating system. It lowers friction of power unit parts, due to which its lifetime limit increases, operation efficiency improves and fuel consumption is reduced. It promotes cooling of engine components, cleans them from dirt and carbon deposit, protects against corrosion.
Engine oils classification
- SAE. It is based on viscosity characteristics of oils at different temperatures. It is developed by the community of motor transport engineers SAE International. Due to this classification, all lubrication materials can be divided into winter, summer and all-season ones.
- API. According to the classification of American Petroleum Institute, all lubrication materials can be divided into the following groups: S – for petrol power units, C and F – for diesel ones. According to engine features, each of them is divided into service categories also marked with letters. Products of SN, CK-4 and FA-4 service categories comply with the latest requirements.
- ACEA. European Automobile Manufacturers Association distinguish 3 categories of lubricants according to operation characteristics:
- А/В. For diesel and petrol engines of different configurations.
- C. For new power units with catalysts or particulate filters.
- E. For diesel engines of cargo vehicles and special vehicles.
Types of motor oils according to composition
In classifying basic oils for power units, American Petroleum Institute takes into account not only their composition but also manufacturing technique, thus dividing all products into 5 groups:
- Products made by petroleum distillation without additional treatment.
- Petroleum distillates which underwent additional refinery.
- Petroleum distillates made by the method of structured refinery with preliminary multiple hydrocracking using hydrogen.
- Short-chain polyalphaolefins made by chemical synthesis.
- Chemically synthesized polyether-based products.
More common classification involves division of all products according to composition into 3 groups:
- Mineral. They include lubricants based on I and II groups according to API. They are inexpensive and fit engines with high mileage well.
- Semi-synthetic. Their composition includes no less than 25% of III, IV or V group oils. They are more effective than mineral ones, and cheaper than synthetic.
- Synthetic. Their composition includes no less than 30% of III, IV or V group products. They have an extended replacement interval and dissolve additives well.

FAQ
→ What’s the right oil for my car?
The best way to make the right choice is to consult the vehicle’s owner’s manual. You can also choose engine oil for your car using the selector on our website. Simply select the brand, model, and engine to find the right oil.
→ Which engine oil is best?
Top-rated products best suited to modern high-performance engines:
→ What is the recommended oil change interval?
With modern lubricants, most engines today have recommended oil change intervals of between 10,000 and 15,000 km, but at least once a year.
However, different vehicles have different maintenance needs, and each manufacturer recommends a different oil change interval for their engines.
→ When should I top up the engine oil?
- If the oil level on the dipstick is below the minimum mark.
- If the low oil pressure warning light comes on.
But as a rule, a car engine in good condition won’t need topping up with oil between service intervals.
→ How much oil does my car take?
It depends on your vehicle's engine. For example, a typical 2.4-litre car engine will require 4 to 6 litres of oil.
Our oil selector will find the right oil for your car and show you exactly how much oil you need.
