Can I use API SN instead of API SJ?
Besides, what does API service SJ mean?
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.
Keeping this in consideration, is API SN oil synthetic?
Yes! The following Quaker State products are all licensed by the American Petroleum Institute as complying with the specifications of the new API SN PLUS category: Quaker State Ultimate Durability Full Synthetic Motor Oils - SAE 0W-20, SAE 5W-20, SAE 5W-30 and SAE 10W-30.
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).
