If you go with STP use the red 4 cylinder stuff. About 1800 ppm zinc and phos. It's a lot thinner than the other. I rather would recommend Valvoline Synpower Oil Treatment, 15 oz, which has about 1700 ppm z and p and moly boron and other goodies. Very nice stuff.

Big lots was selling CD2 High Perf Oil Boost which has about 4800 ppm z and p. Also CD2 75K oil add which has about 4000 ppm z and p. There are others if youwant to test them, including some stuff in round quart size by stp and fram.

GM EOS is around 8000 ppm z and p.

Modern oil about 800 ppm z and p. SL was around 1000 ppm. SH IIRC around 1200 ppm.

Citgo Ultralife is 1150 z and 1050 p per phone call to them last year. Or go dual rated diesel/gas oil (SL/CF) which typically has more zddp.
