I'm not saying anything one way or another for or against Amsoil. But I do want to say that there is almost more to the story when you see a picture like that. How many miles were on it when he started to use Amsoil? What were his change intervals?
For instance, did somebody else change the oil once every two years for 10 years / 200K miles, then your buddy buy it and start using Amsoil?
If he bought that car new, started with Amsoil, and changed it every 5K and it looked like that, than that really sucks!
