Lubricant additives ! Do not mix any lubricant additives with the engine oil. This could damage the engine. Damage resulting from the use of such lubricant additives in the engine oil is not covered by the Mercedes-Benz Limited Warranty. 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. Using the table below, make sure that the SAE classification (viscosity) is sufficient for the temperatures at which the vehicle is operated. The low temperature characteristics of engine oils can deteriorate significantly, e.g. by aging, soot and fuel deposits. It is therefore recommended that you carry out oil changes regularly using an approved engine oil with the appropriate SAE classification. ! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. Otherwise, you may cause damage to the engine or exhaust gas aftertreatment; this is not covered by the Mercedes-Benz Limited Warranty. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment. Mercedes-Benz recommends MOBIL OIL. The table shows which engines oil have been approved for your vehicle.
