Each vehicle manufacturer recommends certain grades of lubricants for use, which have been harmonized and tested during production to meet the requirements of a particular vehicle. This condition also applies to Mercedes-Benz vehicles, therefore, when carrying out repair work, the company's recommendations for the use of certain oils, greases and other materials should be taken into account. Loctite is frequently referred to in this manual. It is a locking liquid for nuts and bolts that prevents spontaneous loosening of threaded fasteners. And although the text only refers to Loctite, products from other manufacturers may nevertheless be used.
The same applies to greases and sealants.
