Products for medium-speed engines

New fuel and engine combinations are placing increased stress on lubricants due to contaminants from soot, sludge and asphaltenes. Castrol’s range of 4-stroke engine lubricants delivers enhanced protection against contamination and lowers oil consumption.

Optimal solutions for 4-stroke engines

We understand that you want to protect your medium-speed engine, meet your operational goals, and remain compliant with environmental legislation. However, lubricants in 4-stroke engines are constantly exposed to combustion products, which place great demands on them.

 

Castrol MHP and TLX ranges are high-quality, high-performance solutions for diesel engines. They provide exceptional viscosity control and BN retention – helping extend oil life, reduce operating costs, and keep engines clean.
