10W/40SF engine oil question, SF??

[robbobnob]

Hi, Could someone please describe what the SF stands for. Obviously it's the reccomended oil but what's the difference compared to SJ etc, what ever SJ stands for. Could i use non SF oil in a engine for SF oil? Not sure of the importance. Obviously engine oil grades are important. Thanks Rob

Some oils may carry a dual classification, such as SJ/CE or SF/CD. This means that the oil meets the requirements for both grades listed. SF oil can be used in engines that require SE, SD, SC, SB or SA oils, as it surpasses the performance requirements of all these other grades. SJ oil is required in all 1996 and newer model autos to meet manufacturers' specifications.
