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

  1. 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.
  2. 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.
  3. ACEA. European Automobile Manufacturers Association distinguish 3 categories of lubricants according to operation characteristics:
    1. А/В. For diesel and petrol engines of different configurations.
    2. C. For new power units with catalysts or particulate filters.
    3. 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:

  1. Products made by petroleum distillation without additional treatment.
  2. Petroleum distillates which underwent additional refinery.
  3. Petroleum distillates made by the method of structured refinery with preliminary multiple hydrocracking using hydrogen.
  4. Short-chain polyalphaolefins made by chemical synthesis.
  5. Chemically synthesized polyether-based products.

More common classification involves division of all products according to composition into 3 groups:

  1. Mineral. They include lubricants based on I and II groups according to API. They are inexpensive and fit engines with high mileage well.
  2. 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.
  3. 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.

→ 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.

Before i tried this oil i had Castrol Magnatec(factory recommended) and i didnt like it coz it was 'evaporizing'. If you like Castrol get the Edge Pro series(hard to find). Then i tried the Mobil Super which kind started almost ruined my dpf(yes i checked it before to make sure its compatible). Then afetr 6.000k km not miles it evaporized more than Magnatec before. Now i have this Valvo and its amazing. To be safe i buy 8-10litres in case it needs to be refilled and every 10k km i drain it completely. I run only on Shell V Power which is the cleanest fuel where i live
