This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. Official classifications. West Texas Intermediate (WTI) crude oil is a good example of sweet crude oil, while oil from Canada and the U.S. Gulf Coast tends to be sour. That's right, motor oil … (2) Not required for Non-ILSAC viscosity grades. The first three groups are refined from petroleum crude oil. That's why it's important to understand API ratings.

It can be diluted with lighter hydrocarbons to produce diluted bitumen , which has an API gravity of less than 22.3°, or further "upgraded" to an API gravity of 31 to 33° as synthetic crude . Since 1930 there have been 12 different classifications of motor oil. When you are choosing a transmission or gear oil you might be wondering what GL-4 and GL-5 mean and what the differences are between these two classifications. API Engine Service Classifications. Old motor oil and even some newer blends (when used in older engines) can cause harm to your engine. Crude oil's viscosity can vary from a low-viscosity liquid to up to tar-like, nearly solid form. Service fill oils for gasoline, light-duty diesel and heavy-duty diesel engines. API’s Engine Oil Licensing and Certification System ... Engine Oil Viscosity Classification, also play a critical role in defining the program. In some occasions, categorization depends on the region from which the oil is extracted.

Breakdown of new and old classifications is included Includes bibliographical references (page 2) Caption title "Filing code: 1525 (P-401)." This is because it indicates the vehicle model year the oil was formulated to service. While SAE grades use numbers and W to classify oil viscosity (for example 20W-40, 10W-30), the API specification tells if the oil meets the required quality and performance standards defined by the OEM. Almost every lubricant used in plants today started off as just a base oil. Vehicle owners should refer to their owner's manuals before consulting these charts. For example the Iraqi Basrah Heavy oil has an of API Gravity of 23 (which place it as medium) yet it is being traded as heavy oil.

Classifications are made based on the sulfur content as well. Bitumen derived from oil sands deposits in Alberta, Canada, has an API gravity of around 8°. The American Petroleum Institute (API) engine oil classification system was set up as a joint effort by API, ASTM (American Society for Testing and Materials) and SAE (Society of Automotive Engineers). These can be purchased through their sponsoring organizations. "Light" vs. "Heavy" Crude Oil Crude oil's classification as either “light” or “heavy” depends on the oil’s relative density, based on the American Petroleum Institute (API) gravity. In this brochure the API Service Categories are summarised in easy to use charts. And SA is not hard to find mixed in with SM on the shelves at c-stores and others. In 1970, along with the SAE and ASTM (American Society for Testing and Materials), they established the API Service Classification System to define the performance level of a given oil, unrelated in the main, to oil viscosity.The API requirements S for Spark Ignition (petrol) and C for Compression Ignition (diesel) can be briefly described as follows. When purchasing oil, the oil has a quality level (API Service). The designation API GL-1 denotes lubricants intended for manual transmissions operating under such mild conditions that straight petroleum or refined petroleum oil may be used satisfactorily.
