Carbon Residue
Standardized Tests Which Measures the Amount of Carbon Left Behind after Combustion under Standard Conditions.
Cetane Index
A Value Calculated from the Density And
Distillation Mid-point Temperatures of a Fuel.
Coc

Detergency
Property of a Lubricating Oil to Reduce Or
Prevent Deposits Formed under High Temperature Conditions as a Result of the System When the Oil Is Drained.
Disperancy
Property of an Oil to Disperse and Suspend
Potential Deposit Forming Materials. They Can
Then Be Removed from the System When Oil Is Drained.

Prescribed Conditions.
Emulsion
A Fluid Which Will Disperse to Form an Emulsion in Another Liquid. In Most Emulsions One Material Is Aqueous and the Other Is Oil.
Ep Additive
Extreme Pressure Additives Are Chemical Compounds Imparting Extreme Pressure Characteristics to a Lubricant with the Objective of Reducing Wear under Conditions Where Rubbing or Sliding Accompanies High Contact Pressures, as in Heavily Loaded Gears.
