Good question. I've been using Mobile-1 10W-30 for the last few oil changes and I am due for one in 200 miles. I plan to keep going with Mobile-1....

Additional designations of quality may also be present, but SE, SF, SG, SH or GF-1 must be included.


So I look at my new bottles of Oil and they don't seem to match any of those??? The bottle has ILSAC GF-4 API SM, SL/CF

Am I good to go, or did I find the wrong stuff?

Enquiring minds want to know!
