I have to laugh there is a show on History channel right now talking about oils and they are showing Amsoil right now.

I also have to say I am having a tough time finding a good comparison chart that isn't done by Amsoil now. I found a couple like one done by Penzoil but it didn't include Amsoil.I am still not feeling very well and am going to give up the search soon.

I learned all I need to know about life by killing smart people and eating their brains.
