Thank you for the AMSOIL Technical Service Bulletin. I wrote an e-mail to
AMSOIL, but I got no answer. In Switzerland nobody sells AMSOIL, but
then I found a dealer in Germany. So I could buy Z-Rod 10W-30.
Thank you again. It is great that I may ask questions here in this forum.
In Switzerland I think nobody is interested in the right stuff for American
cars. It's the same with the '64 Impala SS 409. For this car it is
great that I found buddies driving 409s too, same as here with the ZR-1.
