Abstract
An overbased calcium sulfonate detergent having a high viscosity is characterized by forming a clear solution in lubricating oil, having a TBN of about 400 or more, and having a viscosity of at least 180 mm /s at 100° C. The high viscosity of the detergent allows for reduction in expensive high viscosity oil components of marine cylinder oils while maintaining selected TBN and viscosity parameters in the finished oil.
