Mercedes-Benz GLK-Class: Engine oil viscosity
Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin.
Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures. The following table shows the correct SAE classification to be used. The low-temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification.
Please bear the following in mind
The engine oils are matched to the performance of Mercedes-Benz
engines and service intervals. You should therefore only use engine oils and oil
filters that are approved for vehicles with mainten ...
