MEDIUM SPEED ENGINE

Castrol’s marine oils for medium-speed engines, including our Castrol TLX range, provide extended engine protection and excellent engine cleanliness – even under extreme marine operating conditions.

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 four-stroke engine lubricants delivers enhanced protection against contamination and lowers oil consumption.

OPTIMAL SOLUTIONS FOR FOUR-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 four-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.
