Had this on the list of things they wanted to do in today’s service… Performance oil service - recommended every 18,000km. ”Restores power and protects your engine from harmful deposits left from oil breakdown.” Its $99. The Telluride has 15,000KM on it and is a couple years old. I’m curious as I worry about warranty voiding as well. Is this really a thing?
