Any manufacturer has the right to require motor oil meet certain specifications. If you use non-manufacturer branded motor oil that meets those specifications, and change the oil at manufacturer recommended intervals, they cannot legally deny a warranty claim based on improper lubricant or OCI. OTOH, if you use a lubricant that does not meet the manufacturer's specification, you are taking a chance.
I stand corrected on Scheaffer being API certified, it has the donut but no starburst. That said, certified or not, they do "meet or exceed" api specs. So, if your owners manual reads like NavyDood's 04 dodge above then does that not keep you in the clear?
