i've used pennzoil for over 12 months i think and drive the hemi hard off road a lot of soft sand or sloppy tracks and everything is A.O.K. mds always works and yes a little valve gear clicking when idling but it is a hemi, even the old 426 hemi and my dad had the 392 and 223 50's hemi's they all had loud valve trains when hot and idling
