Service products 361 The specification and availability of lubricants may vary. Some lubricants are no longer avail- able, especially for older vehicles. Further information can be obtained from a Mercedes-Benz Service Centre. Engine oils Notes on engine oils ! Engine oils other than those of the quality specified in this Operator's Manual are not permitted. Brake fluid Only use engine oils complying with Sheet No. 228.51 or 228.31 of the Mercedes-Benz Specifications for Service Products. Engine oils according to Sheet No. 228.51 have a higher quality standard and have a favourable effect on: G WARNING Service product can be poisonous and haz- ardous to health. There is a risk of injury.
Observe the instructions on the respective original container when using, storing and dis- posing off service products. Always store ser- vice products in the sealed original container. Always keep service products out of the reach of children. R length of oil change intervals R engine wear R fuel consumption R exhaust emissions G WARNING The brake fluid continuously absorbs mois- ture from the air. This results in the boiling point of the brake fluid lowering. If the boiling point of the brake fluid is too low, vapour pockets may form in the hydraulic clutch actuation system when it is subjected to a heavy thermal load.
In this case, the function of the hydraulic clutch actuation system is restricted. There is a risk of an accident. Have the brake fluid renewed at the prescri- bed intervals. i You can find information on the quality grade, e.g. Sheet No. 228.51, and the vis- cosity, e.g. SAE class 5W-30, from the des- ignation on the oil container. Before delivery, an engine oil according to Sheet No. 228.51 and SAE class 5W-30 will be filled. Scope of application Technical data Multi-grade engine oils complying with Sheet No.228.51 or 228.31 can be used all year round. Depending on fuel quality (sulphur content in fuel), oil change intervals must be shortened. !
Brake fluid corrodes paint, plastic and rubber. If brake fluid comes into contact with paint, plastic or rubber, rinse with water immediately. Oil change ! If the SAE class (viscosity) of the engine oil used is not suitable for continually low outside temperatures below -20 †, this could cause engine damage. The specified temperatures of the SAE class always refer to freshly added oil. Engine oil ages during driving due to soot and fuel residue. This impairs the charac- teristics of the engine oil, particularly at low outside temperatures. Have the brake fluid replaced regularly at a qualified specialist workshop. You can find the intervals for brake fluid change in the maintenance booklet.
Only use brake fluid approved by Mercedes- Benz, according to MB Approval 331.0. Infor- mation about approved brake fluid can be obtained from a qualified specialist workshop or at http://bevo.mercedes-benz.com . Z
