I have been using Rotella T with a bottle of zinc additive in my puller, I use Rotella and Amsoil in my farm tractors. I have my puller engine torn down and it has a lot of carbon on the pistons and head and plugs after just one season, I'm going to switch to something else, I'm thinking Amsoil 15-40. What do you think of the zinc additive??

if you want a higher zinc oil, use amsoil z-rod line. theyre 10w-30 z-rod should be more than adequate. if you want you can email me or call 419-204-0846.

Zinc is simply an anti-wear additive. When the engine heats up, the zinc bonds to the metal and protects the engine better in a cold start condition.

In a puller, not sure it is doing that much for how long we run them.

Well you must be wrong in your assumption of what Zinc is used for and my reason for this is when I hauled nothing but motor oil to Natural Gas facilities the main difference in most of the oils I hauled was the amount of Zinc in the formula. These engines never shut off, if possible they ran 24/7 some of these engines had run continuously for several years after overhauls. What I was told about the extra Zinc was mainly for valve life. Keep in mind these were engines that sometimes were made as far back as the 1920's and some were brand new. So I'm sure they are not worried about the cold start up.
