Re: Motor oil
According to the oil company Chemist's I've talked to, you need 1100 ppm ZDDP for the old flat tappet cams. Rotella T has 1200 ppm, Valvoline VR1 has 1200, the 'not street legal' has 1300 BUT you need to change the oil every 500 miles because it doesn't have all the additives, Brad Penn is the old Kendall GT1 and has 1500 ppm.
