Tim Mills is great! He is as good as Frank, who sells the Auto-RX. I bought stuff from him and he is willing to sell small quantities. In comparison, I emailed the Schaeffer's rep in Colorado and never even received a reply to my email. After my experience with the Colorado rep, I figured I would never buy any Schaeffer's Oils product. But Tim Mills is completely different! I am going to try Schaffer's Oil in my car before I buy a caseful. I am very happy with the Chevron oil I am using right now (I started using it after people at this site said that it was good oil), but Schaeffer's Oil is apparently a considerable bit better. Some people talk about the Schaeffer's being expensive, but the part synthetic is only about 3 bucks-Mobil 1 right now is something like 5 bucks and change! Now yes, there are shipping costs, but if a person decides they like Schaeffer's Oil, you can buy by the caseful. Obviously, people like to buy for as low of a price as they can, but you do have to pay for quality. I am going to start using K&N oil filters again. They cost about 10 bucks, but if they flow much better and help your engine last (your engine costs thousands of dollars), what does it matter if they cost 5 bucks more than a Pure One, or a Wix, or a Hastings? If you do four oil changes a year, what is twenty bucks? I figure the Schaeffer's Oil really costs about the same as a good conventional oil-after all, you can go 6000 miles with the Schaeffer's Oil.
