I talked to this guy today and was extremely unimpressed. It was the TOP guy and he was clueless. Had no idea what HTHS was, no idea what NOACK was, no idea why I would care about either of them. He repeatedly slammed Redline and Amsoil calling them shams and scammers who made up their own numbers. All I wanted was the viscosity at 40C and 100C, the TBN, the HTHS and the NOACK for the 0w-5 oil. He finally agreed to look the numbers up if I sent an email, though I mentioned that my last three emails to him went unanswered. Has anyone gotten this information before? The oil sounds like a very good oil that should be between a standard 0w-20 and 0w-30 in true viscosity. It may make an excellent oil for all of the cars requiring 5w-20 oils.
