What are Car Manufacturers’ Approvals (OEM approvals)?

OEM approvals (Original Equipment Manufacturer) are specific standards developed directly by automakers (such as Volkswagen, Mercedes-Benz, BMW, Ford, GM, Toyota, etc.). These tolerances are much more detailed than the general API and ACEA classifications, and they take into account the unique features of specific engines, materials, technologies, and systems used by the automaker. For example, the MB 229.5 tolerance from Mercedes-Benz has its own specific requirements for replacement intervals, energy-saving properties, anti-wear characteristics, and compatibility with vehicle systems.

Oil manufacturers conduct additional tests of their products in order to obtain approval (approval) from car manufacturers. The presence of such an approval on the oil packaging is a guarantee that it fully meets the requirements of the manufacturer of your car and will be safe for the engine. Using oil with the correct OEM approval is the best way to maintain factory warranty obligations and ensure optimal engine performance.
