What is API in motor oil? API stands for the American Petroleum Institute. The organization evaluates every blend of motor oil. It assigns an API rating to motor oil blends that meet ILSAC’s current standards. ILSAC stands for International Lubricant Standardization and Approval Committee.
What is the difference between API and SAE? SAE is the Society Of Automotive Engineers (USA). The SAE rating of an oil is a measure of its viscosity (eg 20W50). API is the American Petroleum Institute. The API rating of an engine oil covers the performance rating of the oil (e.g. SM for petrol, CF for diesel).
What is the highest API service rating for oil? SM
The API’s current highest rating for motor oil is SM.
This oil is intended for all gasoline engines currently in use and has been the standard since 2004.
For diesel engines, the current top oil rating is CI-4.
What is the highest API? Generally speaking, oil with an API gravity between 40 and 45° commands the highest prices. Above 45°, the molecular chains become shorter and less valuable to refineries. Crude oil is classified as light, medium, or heavy according to its measured API gravity. However, not all parties use the same grading.

What is API Service SM oil?
Oils that satisfy API Service Category SM are superior in performance to those meeting API SL and earlier and can effectively lubricate engines calling for those Service Categories. This leads to API SM being seen to a wide range of lubricants of different performance levels and viscosity grades.
Is API SN better than SL?
API or american petroleum institute certifies the oil grades which are updated after every vehicle gets a upgrade according to emission standards so a API SL is a older grade used primarily in BS3 compatible vehicles compared to API SN which is being used for latest BS6 compatible engines so if u use a older grade like
What is an example of an API rating?
The service rating is shown in the API “Service Symbol Donut” on the product label.
Whereas the labeling on the bottle of engine oil may suggest the product is a 10W-30, note, if there is no “W” between the 10 and the 30 it may not be a 10W-30.
As an example, a SAE 10-30 is not the same as an SAE 10W30.
Is API SN higher than SJ?
As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.
Is SJ oil better than SG?
In summary, API SJ represents an improved quality level of motor oil vs API SH.
API SJ oils can be used in any applications where SH oils were being appropriately used.
So if your owner’s manual calls for an API SE, SF, SG or SH motor oil – API SJ will work just fine.
What is SJ rated oil?
Category SJ was adopted in 1996 to describe engine oil first mandated in 1997. It is for use in service typical of gasoline engines in present and earlier passenger cars, vans, and light trucks operating under manufacturers recommended maintenance procedures.
How is API calculated?
#API score is calculated by dividing the actual score by 10 which is 1.5 API score. Category III: Research and Academic contributions.
Is higher API oil better?
API gravity of crude oil grades
What API means?
application programming interface
An API is a set of definitions and protocols for building and integrating application software. API stands for application programming interface. APIs let your product or service communicate with other products and services without having to know how they’re implemented.
What is the difference between API SN and SM?
The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons. Better sludge control. Better seal compatibility.
Is SAE synthetic oil?
Conventional vs Synthetic Oil Properties
What is SAE 30 oil?
SAE 30 oil is a motor oil that has been given a viscosity rating of 30 by the Society of Automotive Engineers, according to AA1Car Automotive Diagnostic Help Center. Motor oils typically have ratings from 0 to 50.
What is API SN?
What is “API SN PLUS”
What oils are API certified?
Today, the most common grades are 5W-30 and 10W-30.
Although the majority of vehicles currently on the road in the US specific the use of motor oils meeting a specific API Service Category, some vehicle manufacturers require use of lubricants that meet the original equipment manufacturer’s (OEM) specifications.
What is API CF?
API CF was introduced for the service typical of indirect injection diesel engines, mostly used in off-road applications such as mining and construction.
These engines use a broad range of fuel types, including fuel with higher sulphur levels.
What’s the purpose of engine oil?
The main role of engine oil is to lubricate the engine parts, which are in constant friction. It thus reduces friction which tends to increase wear & tear of engine parts. The energy is lost through combustion and the friction between mechanical parts causes the engine temperature to rise.
What is the API certification?
API Certified is a classification that identifies the licensed organizations belonging to the petroleum industry, which have passed the quality test and complied to the specifications set by the American Petroleum Institute.
