Additives

• Rust Corrosion Inhibitors
• Friction Modifiers
• Viscosity Modifiers

• Prevent engine rust and corrosion
• Reduce fuel consumption
• Maintain low oil consumption and reduce viscosity
  change with temperature

Important Characteristics

• API Rating
• Viscosity
• Viscosity Index
• rate of change from 37.7C to 98.8C
• higher VI (90 and above) is considered a better
  quality oil
• Flash Point
• temperature at which oil will flash when
  exposed to a flame
• Pour Point
• lowest temperature at which the oil will pour.
• Other characteristics such as
• gravity, color, carbon, etc.

What is Viscosity?

• The Role of Viscosity
• Viscosity is a measure of the oils resistance to
  flow
• An oils resistance to flow is responsible for
  most of the drag put on the starter during
  cranking
• The Cold Cranking Simulator and Mini Rotary
  Viscometer are the primary tests used to define
  the SAE W viscosity grades
• Adequate viscosity at the operating temperature
  provides a thick, continuous film of oil between
  moving engine parts, hydrodynamic viscosity
• Adequate viscosity on piston ring surfaces and
  cylinder walls help seal the combustion chamber
• Too much viscosity at the operating temperature
  can create added resistance, resulting in
  increased fuel consumption, reduced heat
  transfer, and increased oil consumption
