69 Charger R/T 440
Out: M1 15w-50 @ 996 mi, 11 months (removed oil pan to replace front seal and timing chain cover, and upgrade from factory windage tray to Jegs one-piece gasket/windage tray, so early oil change). UOA results pending.
In: M1 15w-50, K&N #3001 filter. I think the flat tappet cam (Mopar .474”/280 degree, aftermarket valve springs) needs the ZDDP, otherwise I'd be running the M1 0w-40.
