Thks for advice with MAGNATEC , it's 5w30 seems like a blend (semi synthetic) not like 5w20 and 0w20 that are full synthetic (probably group III though) . I think 0W30 or 0w40 are superior group IV full "real" synthetics and heat in Florida heat maybe too much for 5W30 Magnatec in this DIT application . I plan to keep 7500 miles oil changes...
