300F. Read the test requirements for new SM/SN API certified oils. Why do you think the Z engineers decided on the limp mode temp of ~280F and not 260, 240, 264, 228, etc? The 260F temp limit is passe and old oil technology. Newer materials technology can withstand higher temps for modern cars thus the requirement for SM/SN oils.
