Rotella plus a bottle of break-in additive.


the very next thing i would do, if you have a oil filter cutting tool, check the filter for metal..
if you do not have a cutting tool.. drain the oil through a paint strainer or a coffee filter. tip the filter and drain it too . look for metal. a small amount is expected. if you have lots of metal. there is no need to go any further.. the motor is hurt. if you have no metal keep searching good luck
