Red Line, like the majority of Amsoil's line up...and RLI, isn't officially licensed by the API.
Regarding warranty, you might be taking a gamble if the dealer is dead set on voiding your warranty. I've heard stories on the 'net, but have yet to witness or personally hear of an instance where the dealership went investigating the oil unless there was an obvious lack of maintenance and I surely haven't seen a dealership or factory field rep send an oil off for UOA just to make sure it has SM ZDDP levels.
