I recently ordered 4-1g jug case of their 15w-40 Diesel oil thru their web site. Was shipped and billed for 2-2+1/2g jugs. This fact combined with 2 e-mails sent to Amsoil's customer Service (to which I received no replies) and the fact that I find their WEB page unusually comfusing and difficult to navigate caused me to write a letter to their President. I did this, more to get it off my chest than to try and change things.
Suprisingly, I received a personal phone call from Joe A. , Amsoil's president, apologizing for the above and promising that he did not want his company doing business this way. He said a personal letter was going to follow after he "looked into" what I had said.
I know they have a quality product. Obviously they have some personel problems but, IMHO, their President is a class act.
