All our reviews are based only on expert assessments or practical experience with most of the oils we consider. We aim to ensure that our management is independent.

Which engine oil 5w-20 should I choose for my car?

  1. Choose engine oil 5w-20 according to the manufacturer’s recommendations (must be listed in your vehicle’s service book)
  2. Use the engine oil 5w-20 that is already in your vehicle’s engine (this information must be in the service book)
  3. Choose oil according to the recommendations of the engine oil 5w-20 manufacturer by selecting the make of vehicle on this site

How to choose engine oil 5w-20:

In order to choose the right engine oil for your car, you need to study the manual of your car and find in it the requirements for the applied engine oil. Pay attention to the viscosity, specifications, and tolerances of car manufacturers.

For each engine oil in this article, we have indicated the specifications and tolerances of car manufacturers, thanks to which it will be very easy to choose an oil for your car.

If the information on tolerances or specifications is not available to you for some reason, select the oil selection menu by car make and model. We have selected the best motor oils for all popular cars.

Engine oil 5w-20 types:

There are three main types of motor oil: mineral, semi-synthetic, and fully synthetic oils.

  • Mineral oil is the least refined type of motor oil, which provides the least engine protection, is less productive, and less economical.
  • This means that such oils cost much less than other types of oil.
  • Semi-synthetic oils are a mixture of synthetic and mineral oils that provide more performance than mineral oils, but cost much less than synthetic oils.
  • Fully synthetic oil is the most refined type of oil and at the same time the most expensive type of motor oil. Synthetic motor oils provide maximum protection and economy for a car’s engine.

Engine oil viscosity:

The viscosity grade of engine oil is determined by the requirements of the international SAE standard. For each type of engine, you must use oil with the optimum viscosity, which depends on the design and age of the engine, its mode of operation, and ambient temperature.

  1. The first number before the letter “W” indicates the oil’s viscosity at low temperatures. The lower the number, the more fluid the oil is, and the better it flows at low starting temperatures.
  2. The second number refers to the flowability of the oil at high temperatures. This oil is thicker and better suited to protect the engine at high temperatures.

Engine designs are designed for medium and low viscosity oils. For new engine types, 5w-20 oils are recommended. As the engine ages, the choice of oil shifts toward a higher viscosity.

Engine oil standards:

  • The American API standards provide for two groups of classes for vehicles: S for gasoline engines, C for diesel engines (API: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, SN Plus, SA, CB, CC, CD, CD, CE, CF, CF-4, CF-2, CG-4, CH-4, CI-4, CI-4 Plus, CJ-4).
  • The European ACEA standard uses four groups: A for gasoline engines, B for diesel engines, C for engines with catalytic converters, and E for heavy diesel engines. ACEA: A1, A2, A3, A5, B1, B2, B3, B4, B5, C1, C2, C3, E1, E2, E3, E4, E5, E6, E7.
  • Asian ILSAC standards: GF-1, GF-2, GF-3, GF-4, GF-5, IGF-6 define quality standards of oil for gasoline engines of passenger cars.
