Sorry to say, but these Honda V6 engines have issues and I would stay away from them... Honda knows about piston ring and knocking issues/cylinder wear. These engines need to have early 3-4K mile OCI's with a really good cleaning motor oil. PP, Redline, etc... I know all this because I used to own Acura MDX's and will not buy them ever again. Got to know a few Acura mechanics and they told me Honda knows that they have serious V6 engine issues. Do some internet searching and you will find more info...
