yes i added few oz of shaeffer's oil moly ep, amsoil and shaeffer's are my top two oil
that is why i refilled it will shaeffer's 9000 series so i could compare some numbers
a mix of both city and highway driving, before i drove the truck i waited until temp showed 100F and babied it until fully warmed up,
i did refill with schaeffers oil 9000 5w-40 instead of amsoil, just wanted to see how the numbers would compare between the two oil
no towing
