ZR-1 Franz · 02-09-2013

Until now I used Mobil 1 Synthetic Motor Oil SAE 10W-30, especially for
the ZR-1 and for the Chevy pickup K 3500 4x4 with the 454 engine, but
also for other Chevrolets we own.
Now I would like to change to Amsoil. Amsoil says for these two cars that
SAE 10W-30 Signature Series is the best choice.
If I remeber right there was a discussion here whether it would be
better to use an Oil with Zinc additive, this would be Amsoil Z-Rod 10W-30
Synthetic Motor Oil. What do you think? Thank you for your help.
