The amsoil AME 15-40 is a good oil with zinc
for the best Zinc levels.

Ok ill look in to that thanks. They have a marine 15-40 that is full synthetic? I would think they would but just never looked in to it.Amsoil is good oil, but the on highway version still has much lower zinc than it use to. If you wan the best amsoil possible run the 15-40 marine oil. It does not have to conform to the new stringent on highway standards.
BTW I believ Amsoil 15-40 is what Scott O'hagan was running when he wiped out his stock cam. Run the Marine version for the best Zinc levels.

Good question.How much zinc is to much zinc? I talked to amsoil and they said you can actually run to much zinc. At what point is to much with one of your cams in my truck
We typically put in two bottles for break in, or if someone is running a radical cam with a lot of lift and duration at high rpm. That is the most we suggest and we have not had any issues with that. If it were me I would not excede this amount and then you won't have to worry about too much. On all of the other street trucks we suggest one bottle per oil change.

The AME 15-40 says diesel/marine. I take it your talking about something diffrent?Amsoil is good oil, but the on highway version still has much lower zinc than it use to.

What is your opinion on Valvoline Premium Blue 15w40? It is approved by Cummins, but I wonder if they actually did testing on the oil or if it is a marketing sceme.
