The “S” series is composed of SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM and SN. SN oils provide higher levels of performance than all the other “S” oils. API Categories SA through SH are obsolete, and oils labelled SN can be used in their place.
Full Answer
What is the difference between API SM and SN?
The first letter, S, indicates the oil is for gasoline engines. The codes are as follows: • SN: For vehicles manufactured after 2010. • SM: Vehicles manufactured between 2002-2009. • SJ: Vehicles manufactured before 2001. Likewise, what is the difference between API SM and API SN?
What is API SN oil?
The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons. In this manner, is API SN oil synthetic? Yes!
What is the difference between API SL and SM and 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.
What does API SJ mean on oil?
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. Besides, what does API service SJ mean? The first letter, S, indicates the oil is for gasoline engines.
Can I use SN oil instead of SF?
The “S” series is composed of SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM and SN. SN oils provide higher levels of performance than all the other “S” oils. API Categories SA through SH are obsolete, and oils labelled SN can be used in their place.
Can I use API SN instead of SP?
The API SP standard is fully backward compatible with previous API specifications, including API SM, SN and SN Plus.Sep 4, 2020
Is SN better than SF oil?
Is Sn Better Than Sf Oil? The performance of SN oils is higher than that of all other “S” oils. The Ultra multigrade gasoline engine oils meet the highest API specification (API SN), these oils have been tested and proven to provide the best protection and performance for today's modern engines.Dec 1, 2021
Can I use API SN instead of 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.Jan 9, 2021
Can you mix API SN and SP?
API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.May 1, 2020
Does SN mean synthetic oil?
Oil that is synthetic is referred to as sn. Synthetic oil is most likely to be referred to as'sn'. This oil meets all synthetic oil requirements and standards.Dec 4, 2021
What is API SN in engine oil?
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.
What is API SN oil?
What is “API SN PLUS”? API SN PLUS is a new motor oil specification developed for turbocharged engines that is being developed in response to automakers request for motor oils that protect against Low-Speed Pre-Ignition (LSPI).
Is API SN backwards compatible?
The API SN Plus specification was created to quickly combat issues that come with newer TGDI engines and Low-Speed Pre-Ignition (LSPI) concerns. This new category is fully backwards compatible with API SN, because the “Plus” adds additional testing for the LSPI problem.
What is API SF CD?
An API service rating of “SF” means the oil meets all new car warranty requirements for 1981 and newer models. “SE” means the oil is usable in all 1972-1980 vehicles. “SD” means the oil is good for all 1968-1971 cars.Jan 14, 2019
What You Need to Know About ILSAC GF-6 and API SP
ILSAC GF-6 and API SP are new, higher performance passenger car oil categories.
API SP
SP is the API’s newest service category. ILSAC GF-6 applies to the fuel efficient viscosity grades, while API SP applies to those heavier viscosity grades like 10W40 and 20W50.
Why Have These New Motor Oil Specifications Been Developed?
ILSAC GF-6 and API SP have been developed in response to three major drivers:
The Benefits of the GF-6 and API SP Motor Oil Standards
The ILSAC GF-6 and API SP motor oils will offer a range of benefits for the environment, OEMs, and consumers, including:
