mystic (and Frank):
If you've run a "clean and rinse" in your engine (less than 100K miles) and you're now using a 3-4 ounce maintenance dose with each oil change, why would you need to "re-clean" the engine again?
I put an Auto-Rx maintenance dose in my wife's '05 Highlander 3.3L V6 at the first OCI, i.e., 1k miles. It gets PP 5w30 every 5k miles along with 3-4 ounces of Auto-Rx. I hope I'll never need to perform a full clean and rinse on that engine.
BrianWC: nice pics! I wish I'd taken a look under the valve cover of my 2002 9-3SE before I turned it in off of lease in 2005. 5k mile OCIs with M-1 0w40 the first year, then 5w40 the last two years. I might have been surprised!
