As good as Amsoil is I have a hard time with the price differential to Mobile 1. I can get M1 for just over $5.15 a quart plus tax. Amsoil is $11.70 a quart plus tax and shipping. Forgetting about the tax and shipping for the moment 10 quarts is $51.50 for M1 and $110.70 for the AMSOIL. I can add a bottle of zinc addative for $10 to the M1, have an even higher zinc level and still be $50 ahead vs AMSOIL on every oil change. With the exception of zinc (zddp) Mobile 1 is still a great product. Unless someone can convince me otherwise I’m staying with M1 even if I have to include the zinc addative.
