I like to use Wal-Mart Tech 2000 coolant (horrified gasps) in my engines and
the customers who don't absolutely insist on Autobahn stuff (I also have
never seen a connection between using dealer only coolant and longer head
gasket life).

There are three reasons I like to use the Wal-Mart stuff:
1. Phosphate Free
2. Cheap
3. Readily available in any city around the country (so if you have a coolant
leak you don't have to worry about mingling your dealer coolant with some
other coolant).

I know accept the fact that I will be executed as a traitor to the DM.  My
philosophy is that most of the time the DM is definately worth doing, but
there are also times it ain't.  Experience shows when to hold 'em and when to
fold 'em.

My only regret is that I have but one life to give for my coolant :)

Thanks,
Ken Wilford
