As promised, im about to be near my oci for my titan which is currently using the new 5w-30 TSUV M1. I have the Blackstone oil anaylsis kit but i want to know how can i send this stuff off followed by other simple questions? 1)How much is the shipping usually cost for this type of item? 2)Should i use UPS, Fedex, UPSP, DHL, etc (opinions strictly)? 3)Should i boxed the container? 4)Should i tell the mail people im carrying oil/ if it is hazardous etc? Thanks.
