What is the API of heavy oil?
A medium crude is in the 25-35 API range, and a heavy crude is in the 15-25 API range. Anything below 15 API would be considered an extra-heavy crude.
What does API gravity of oil is 14 mean?
The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.
What is API oil classification?
The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. It specifies the viscosity grade required for your car’s engine.
What is the densest oil?
In general the relative density of most oils, both mineral and vegetable, is between 0,840 and 0,960….Density of some vegetable oils:
| Type of oil | Relative density |
|---|---|
| Sunflower oil | 0.918 – 0.923 |
| Soybean oil | 0.919 – 0.925 |
| Peanut Oil | 0.912 – 0.920 |
| Olive oil | 0.913 – 0.916 |
What is the classification of crude oil?
Crude is classified, based on density, as light, medium, heavy, or extra heavy. It can also be classified, based on sulfur content, into a sour and sweet category.
What is the difference between light and heavy crude oil?
Light Crude oil is liquid petroleum that has low density and that flows freely at room temperature. It is referred to as “heavy” because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°.
Can I use SL oil instead of SJ?
The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible.
Is SN better than SF oil?
SN oils provide higher levels of performance than all the other “S” oils. All Ultra multigrade gasoline engine oils meet the highest API specification (API SN), these oils have been tested and proven to provide the optimum protection and performance for today’s modern engines.
