Heehee Naw. Not so bad up here w/o internet in Jellystone. No TV or air conditioning either until today. At least I didn't get eaten by a bear.
Blackstone commented that the insolubles were possibly settled out ad pack, although I turned the bottle over a few times. Maybe I needed to stir it mechanically.
But I'm not still impressed. AAP sells the new Rislone oil supplement that promises on the label to boost zinc to at least SL levels.
Says to use 1/2 bottle for 2004 cars and a full bottle for older--or something like that. And there are plenty of anti-wear ad boosters out there.
I was hoping for proof that cheap old STP would do more than thicken the oil, but I don't see it.
I guess they are relying on traditional "My pappy always used it" rather than making an effort with marketing the performance.
IMO, they should publish some wear test results and ad pack data if it really does anything. (and improve the ad pack too)
You might have better luck adding a quart of Redline to the mix. You would boost the HTHS numbers, TBN, add ester cleaning abilities and add a good amount of ZDDP & PHOS because they love this in their oils!
