Fuel Supplier’s Guide to Castrol Engine Oils 

Cyltech 100

Castrol Cyltech 100 is specifically designed to help prevent corrosion. With a base number (BN) of 100, it offers one of the highest levels of protection on the market with mixed detergents to optimize cleanliness. It is suitable for super long stroke crosshead engines using residual fuels, mainly medium and high sulfur varieties. In some cases, it can also be used with 2014 ECA compliant fuel with 1% sulfur for short periods. 

Cyltech 40SX 

Like all Castrol lubricants, Cyltech 40SX contains high-quality detergents to prevent corrosion and reduce wear and tear. It is designed for two-stroke crosshead engines powered by low-sulfur fuels. Low-sulfur means fuels with 1% sulfur or less. 

Cyltech 70 

Cyltech 70 is a cylinder lubricant designed to optimize performance at higher temperatures and pressures. It is intended for use with low-speed crosshead engines using residual fuels. It works best with fuels that have a sulfur content between 1% and 3.5%. For short periods it may also be suitable for fuels with less than 1% sulfur. 

Cyltech ACT (Ash Control Technology) 

Castrol Cyltech ACT was developed to provide optimal protection for engines burning low sulfur fuels and LNG. Because of its low ash content, it prevents ash deposits from forming when burning low-sulfur fuels. It contains a precise balance of BN (base number) additives, providing optimal ring zone cleanliness and engine performance.
