German oil and additive specialist LIQUI MOLY has highlighted three special oil additives formulated to reduce repair costs and extend engine service life.

Wear is a natural enemy for any engine. Metal on metal abrasion can dramatically shorten the service life of an engine and drive up repair costs. LIQUI MOLY specialises in engine protection and this is well demonstrated in three powerful additives, Oil Additive, Motor Protect and Cera Tec.

Oil Additive is an excellent additive for older vehicles today. It contains MoS2, a solid lubricant, similar to graphite. David Kaiser, Head of Research and Development at LIQUI MOLY says, "It forms a protective layer on the metal surface, preventing direct contact between adjacent metal surfaces in the engine. This is particularly important immediately after starting the engine, before the motor oil has circulated to all points. The Oil Additive has proven itself in cars around the world for over 60 years.

While the solid lubricant in LIQUI MOLY Oil Additive reduces friction in the engine physically, LIQUI MOLY Motor Protect accomplishes this function chemically. It contains so-called friction modifiers, which have a smoothing effect on the metal surfaces with which they connect in the microscopic area. Motor Protect is suitable for state-of-the-art cars and is intended for drivers who want a wear protection additive not containing any type of solid lubricants whatsoever.

LIQUI MOLY Cera Tec combines both physical and chemical protection.  This double protection makes Cera Tec a highly effective additive. It is also economical as each application can provide protection up to 50,000 kilometres.

All three additives reduce friction in the engine. This reduces the engine temperature and even lowers fuel consumption. They also mean the engine is better protected under extreme loads.
