Wow, you have a great AA. I just went to mine and there was nothing good on the clearance rack. I have used it and have at least one or two UOAs where it was used, but confounded by the witche's brew of an oil mix I had. Nobody around here VOA'd it because it was discontinued. STP would not give me any data. All I can say is the label says "Contains olefin copolymer and zinc dialkyldithiophosphate."
If you look at the VOA of STP 4-Cylinder Oil Treatment on this site Butler Cat Lab's report shows 1800 ppm phos and 1960 zinc (ANA Labs 2885 and 2213 for same bottle of the stuff, but I would trust Butler Cat). Anyway, could assume similar level for the 6000-mile Extender, but who knows.
What is the price? I paid $4 each on clearance and some folks (Bror Jace I think) said they got it for a buck a bottle on clearance a couple years ago. If cheap enough I probably would buy it, but the CD-2 Boost stuff is cheap at $1.99 and we know what is in it.
