Castrol HLX is a Super High Performance Diesel (SHPD) lubricant, specially formulated to meet the latest performance requirements of marine monograde lubricant specifications. This allows extended drain periods to effectively compete with performance normally associated with synthetic oils. HLX is available in both SAE 30 and 40 viscosity grades.
HLX, positioned at the top of the Castrol range of mineral based diesel engine lubricants, is formulated for use in very highly rated high speed marine and power generation diesel engines that use distillate fuel with sulphur from zero up to 1% and require extreme performance. It is particularly suitable for high power density applications such as fast ferries.
HLX uses premium additive technology blended in high quality, high viscosity index base oils. It provides high detergency and excellent thermal and oxidative stability required to lubricate today's most severe diesel engine applications. In summary, HLX can enable: Extended oil drain intervals compared to other API CF oils. Excellent high temperature performance. High resistance to bore polishing.
