2. Synthetic oil - Wikipedia

   en.wikipedia.org/wiki/Synthetic_oil

   Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil , but can also be synthesized from other raw materials.

3. Shell Rotella - Wikipedia

   en.wikipedia.org/wiki/Shell_Rotella

   Multigrade synthetic oil—in SAE 5W-40 and 15w-40 viscosity ranges [3] Single grade conventional oil—in SAE 20, 30, 40 and 50; Synthetic blend oil; Shell is marketing their new CJ-4/SM oil as "Triple Protection," meaning it provides enhanced qualities for engine wear, soot control and engine cleanliness.

4. List of crude oil products - Wikipedia

   en.wikipedia.org/wiki/List_of_crude_oil_products

   The chemical profiles, or crude oil assays, specify important properties such as the oil's API gravity. The delivery locations are usually sea ports close to the oil fields from which the crude was obtained (and new fields are constantly being explored), and the pricing is usually quoted based on FOB ( free on board , without consideration of ...

5. Motor oil - Wikipedia

   So periodic oil and filter changes should still be done with synthetic oil, but some synthetic oil suppliers suggest that the intervals between oil changes can be longer, sometimes as long as 16,000–24,000 kilometres (9,900–14,900 mi) primarily due to reduced degradation by oxidation.

6. Oil additive - Wikipedia

   en.wikipedia.org/wiki/Oil_additive

   The advantage of using less viscous oil with a VI improver is that it will have improved low temperature fluidity as well as being viscous enough to lubricate at operating temperature. Most multi-grade oils have viscosity modifiers. Some synthetic oils are engineered to meet multi-grade specifications without them.

7. Benchmark (crude oil) - Wikipedia

   en.wikipedia.org/wiki/Benchmark_(crude_oil)

   Using benchmarks makes referencing types of oil easier for sellers and buyers. There is always a spread between WTI, Brent and other blends due to the relative volatility (high API gravity is more valuable), sweetness/sourness (low sulfur is more valuable) and transportation cost. This is the price that controls world oil market price.
