Bobby Unser's AMSOIL Experience:

I was running the Pikes Peak Hill Climb (in 1976) in a car equipped with a very special rear end that gave me an edge over the other guys. The rear end was fitted with some 1 948 Ford parts which you just couldn't buy anymore. They were getting harder and harder to find, and here I was, destroying some of them in one practice day! Well, I knew that had to stop soon, or I'd have to use a different rear end and probably lose my competitive edge. I called a friend who has a good engineering background and I told him I was looking for a gear lube with the best extreme pressure characteristics possible. His immediate answer was AMSOIL. I called the company in Superior, WI and they put me in touch with a local dealer. Between working with the dealer and Al Amatuzio (CEO of AMSOIL), I learned some amazing things about AMSOIL. I receive products from all over the world for testing and evaluation, but when I put AMSOIL in the rear end, I had never seen anything like it! I went from totally destroying the rear end in one day, to using the one through 3 days of practice, a day of qualifications, a day of racing and it was still good! Where I used to go through one rear end a day, now I used the same one the whole season and it was still like new! I was amazed then, and I still am now.
