I like Amsoil products and use a few myself, but I don't use their oil, not because I think it's bad oil - it's not - there are just better alternatives in my opinion. I've used their grease for my ball joints and tie rod ends for the past 230,000 miles. While the original no grease fitting ball joints were replaced, I'm still running the original tie rod ends at 244,000 miles. That's Minnesota miles, snow miles, sub-zero miles.
I use Schaeffer Oil, American's oldest oil company. Delivered right to my door by my sales representative - who has never once in 14 years of buying from him tried to sigh me up as some kind of dealer or other program in order to get a discount. If interested, here's his web site with complete product information.
