The European motor oils appear to have more zinc and phosphorus.
Car runs great and this is used in my 401 cid LT5. I chose this weight combo for all the reasons mentioned above.

Karl,
Thanks again for the recommendation. I have not drank the AMSOIL Kool-Aid and they will not reasonably ship to military address overseas; Mobil 1 Formula M is easy to get. BTW, your image you posted is blurry AF.
