What does API SJ CF mean?
What does API SJ CF mean?
American Petroleum Institute
The second part, 50, is the measurement of the high end or heavy end of performance at higher operating temperatures. API SJ/CF. API which stands for ‘American Petroleum Institute’ ‚ is an indicator of the performance level of the lubricant as determined by the type of additive package used in formulating the oil.
What does API SJ mean on oil?
Gasoline Engines
| “S” | Status |
|---|---|
| SM | Introduced on 30 November 2004 |
| SL | 2001 Gasoline Engine Service |
| SJ | 1997 Gasoline Engine Service |
| SH | Obsolete |
What is API CF in engine oil?
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.
Can I use API SN instead of API SF?
API SN to SJ are for the most recent cars, API SH to SA for the older cars. If you read the table properly, the car needs an API SF. In theory, both SH and SL could be used. As also explained earlier, more modern oils are not necessarily adapted for older engines.
Is API SN better than 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.
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 the difference between SAE and API?
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).
Is API SN higher than SF?
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.
Can I use API SN instead of SL?
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. However, you have to pay attention to the year of construction of the engine.
What does API SM stand for?
The codes are as follows: • SN: For vehicles manufactured after 2010. • SM: Vehicles manufactured between 2002-2009. • SJ: Vehicles manufactured before 2001.
Is an oil higher than 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.
What would be 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.
