normal oi index

  The term “normal oil index” doesn’t have a widely recognized, specific definition in the oil industry. It’s possible you might be thinking of one of the following concepts:

1. Viscosity Index (VI): This is a common term related to oil, particularly lubricating oils. The viscosity index is an arbitrary, unitless measure that indicates how much an oil’s viscosity changes with temperature.¹

• High VI: The oil’s viscosity remains relatively stable over a wide temperature range.² This is generally desirable as it ensures good lubrication in both cold starts and high operating temperatures.³
• Low VI: The oil’s viscosity changes significantly with temperature, becoming much thinner at high temperatures and thicker at low temperatures.

2. Oil Price Index: This refers to a benchmark used to track and report the price of crude oil or petroleum products. There are various oil price indices globally, such as:

• Brent Crude: A major international benchmark, representing light, sweet crude oil from the North Sea.⁴
• West Texas Intermediate (WTI): The primary benchmark for U.S. crude oil.⁵
• OPEC Reference Basket: The average price of crude oils from OPEC member countries.⁶

3. S&P Global Oil Index: This is an index that tracks the performance of a group of publicly traded companies involved in the oil and gas industry.⁷

To help me understand what you’re looking for, could you please provide more context or clarify what you mean by “normal oil index”? For example, are you interested in:

• How oil flows at different temperatures?
• The typical price of oil?
• The performance of oil companies?

Once I have a better understanding of your interest, I can provide a more specific and helpful answer.
