Schaeffer's is a rather unusual oil company that mainly seems to sell to large accounts. Tim Mills, a Schaeffer distributor, will sell small amount to customers, however. There are some other companies that you don't hear much about that mainly sell to large accounts, such as Lubrication Engineer's. Schaeffer's 7000 blend is cheaper then Mobil 1 (about $3.00 a quart) but of course you have to pay for shipping. There is considerable evidence (check the UOAs-do a search) that Schaeffer's is outstanding in reducing wear. Schaeffer's meets or exceeds all requirements and I believe that it also meets ACEA A3 European requirements, which is very unusual for an American motor oil in the USA. Schaeffer's is used in auto racing to some extent and I came across a web site where a guy said that he saw Schaeffer's oil being used by a race team (probably the synthetic Schaeffer's). There might be some other brand name written on the side of the racing car.
