Perfect candidate for Valvoline Restore and Protect which you have converted to. Keep it down to your new plan and oil combo, should clean up whatever is in there and help curb issues related to the severe service schedule. 6 months max in this situation. You might can go up to a year again, if you switch to a lower ethanol fuel.
For example, Amsoil says if you use E85 or other alternative fuels then the vehicle isn’t a candidate for extended drains at all, that’s for their Signature Series too.
