Kirk, somewhere up there you said "You could buy the CTS and use AMSOIL for example to exceed even the European spec.....here is why"
Is the Amsoil certified to meet the spec?
also, about the GM monitor, a couple of years ago I was at dinner during a conference, the owner of a well known lab was there too.
He knows the lady that headed the algorithm team and spoke highly of her and her efforts.
Good enough for me.
I would discount anything a dealer told me that increased their profit.
My Dodge 2500 came with a 7,500 OCI in the manual, they gave 4 coupons for oil changes at 6,000, and then pput a 3,000 sticker in the window.
Same people told my daughter they couldn't install the filter I sent her with, (Jeep) because it voids the warranty?
Yeah, I trust them. NOT!
This is not about trusting a dealership Per se. It's more about the fact of them dealing with some sludge issues that have occurred in this high tech engine,as well as all the other sludge issues in other cars.
Should the dealers have done nothing to address the issue of sludge???
So now when the dealer attempts to address an issue it's either bogus or an attempt to make more money........now everything is always about an ulterior motive?
Looks like Amsoil works on the CTS........http://www.25000milemotoroil.com/Best-Oil-for-Cadillac-CTS.html
This link will discuss way down on the list regarding oil type and the algorithms for oci's....
