Shell Strombus MP's unique combination of base oils and carefully selected additives, give good emulsibility whilst offering a high level of protection to the metal surfaces, in the presence of water.
Shell Strombus MP absorbs high amounts of seawater. There is no need to reduce the concentration of seawater emulsified in the oil until it reaches levels of over 20%.
Minimising risks of water ingress : Water is absorbed to form a stable emulsion which continues to offer good lubrication and protection against corrosion. The oil and its emulsion are sufficiently fluid to circulate around the stern tube bearing oil system.
