I haven't read it but i don't think they intend on it being used in street vehicles. I help out on a local dirt late model team and we have always used Amsoil products.
I wouldn't even think of using this stuff in a regular street car but we do use it in the race car and change the oil every weekend. I don't think there is anyone stupid enough to use racing oil in a street car at least i hope not. They make other oil for that.
