Sorry if this is stupid.
I was shooting emails back and forth with a Schaeffer sales manager and he says their 9000 5w40 can be used in my jeep.
I just wanted a little more reassurance to be very honest. I saw pictures online and it is only rated CJ-4 with no SL/SM/SN rating. I wanted to try this as something new only to see if my jeep likes it but before that I wanted to know if anyone else was using it in a gasser.
Should I be safe or should I just stick with Delo/Rotella 5w40?
Thank you all!
