Go with a run of the AMSOIL AFL 5w-40.

Ok so we have lots of reccomendations for a 5w40. Is there a certain brand that has shown to be best in the LS1? Also should I stick with Syn or go dino?

seriously - the first thing I'd do is stop all additives and switch to a different oil. some decent recommendations above.
don't be too hard on your advisor - some engines just shed more than others, and no guru in the world can stop that. how low was your previous TBN? does this car have an OLM?

So, you think your OLM is telling you to change your oil too soon? You are having wear metal problems and you change your oil 1k beyond the change interval recommended by your OLM? I think we have found out why you have wear metal problems, and it is not the oil.
