Can I use API SN instead of SG?
can I use SN oil instead of SG? The current specification is API “SN”, introduced in October 2010 for 2011 and newer vehicles (although they can be used in older vehicles as well). Furthermore, although the API does not issue the same cautions for SF, SG, and SH, they make it clear these motor oils are also “obsolete.”
Is API SM better 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.
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.
