What is API oil classification?
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.
Is API SN higher than SL?
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.
What API rating is higher than CF?
CJ-4 oils exceed the performance criteria of CF-4, C-4, AH-4 and C-4.
Is API SN higher than SF?
SN oils provide higher levels of performance than all the other “S” oils.
Is SP better than SN oil?
Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. If an automotive owner’s manual calls for an API SN oil, an API SP oil will provide full protection.
What is API SG grade oil?
API Service Category SG was first introduced in 1989 for use in gasoline engines and is not suitable for use in engines introduced after 1993. API has discontinued licensing engine oils against API SG and it is considered to be an obsolete specification.
Is API SN better than SM?
In 2010 the American Petroleum Institute introduced a new engine oil category under the name API SN and a new supplemental category called Resource Conserving. 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 API SM higher than SG?
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.
What is API SL oil?
Premium Grade Gasoline Engine Oil are designed to prepare for all gasoline and diesel-powered passenger cars, light trucks and van including those fitted with turbo chargers.
Is API SL better than SM?
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.
What is SF 15w40?
MOTOR OIL SF 15W-40 is a multi functional mineral engine oil for older gasoline-, diesel- and LGP engines of passenger car and light vans with or without turbo compressor. MOTOR OIL SF 15W-40 is not suited for engines equipped with a Diesel Particle Filter (DPF).
What happens when TBN is high?
Total Base Number (TBN), is a property that measures oil’s ability to neutralize acids formed during engine operation. Generally, oils with a higher TBN better neutralize acids and combustion by-products, resulting in longer oil life and improved protection against corrosion.
What is API SL grade oil?
It is a series of high quality, shear-stable, multigrade engine oil for use in a wide range of passenger car and light-duty commercial vehicle engines where API SL performance lubricants are required.
Should you use the most current API rating for oil?
It’s always wiser to use the most current API rating for two reasons: Motor oil with any of the current API ratings should still be good to use. If you’re using motor oil with an SJ API rating, proceed with caution. There’s a chance that the oil has expired.
What is the API service category for oils?
Oils may have more than one performance level. For automotive gasoline engines, the latest API Service Category includes the performance properties of each earlier category and can be used to service older engines where earlier category oils were recommended.
What does API stand for 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.
Which oils are eligible for the API certification mark starburst?
Marketers with licensed SN PLUS oils may use SN PLUS in the lower half of the API Donut. Oils licensed by API as API SN with SN PLUS and Resource Conserving and ILSAC GF-5 are eligible to display the API Certification Mark Starburst.
