What Is It?
• Crude Oil is a complex mixture of a vast number of chemical compounds containing:- Mainly Hydrocarbons with- Sulphur- Nitrogen- Oxygen Compounds- Metallic Salts- Water
• The huge number of possible combinations and variations in chemical structure, means that crudes vary considerably from source to source.

Some of the Key Factors
When does it freeze? — Low Pour Point
Refined for Health and Safety
Low PCAs
Good Flow at Low Temperatures
Clarity — Base Oils Must be Clear and Bright — Free from Wax Particles, Free Water, Etc. . .
BA
Strict Quality Checks in Transport
Low Flammability = High Flash Point
Low Volatility
Small Difference in Viscosity at Different Temperatures =
High VISCOSITY INDEX
