Types of oil

Measure of thickness or fluidity

• Viscosity

• Mulit-Viscosity

• Single Viscosity

Fuel efficiency

• F rating

• S rating

• C rating

gas engines /spark ignition

• F rating

• S rating

• C rating

Compression ignited engines

• F raring

• S rating

• C rating

rated for both cold and warm temperatures

• Multi- viscosity oil

• Single viscosity oil

Designed to perform at same viscosity at all temps

• multi-viscosity oil

• single viscosity oil

oil to flow better in cold weather

• pour point depressants

• anitfoam agents

• oxidation inhibitors

• detergents

The four functions of oil include: lubrication, cooling, sealing, and

• cleaning

• heating

• ventalition

These clean engine parts and suspend tiny contaminants in the oil.

• Pour point depressants

• Anitfoam agents

• oxidation inhibitors

• detergents

These additives prevent the oil from breaking down because of reactions with oxygen.
