After 70-90k miles, drain the sludge and have it analyzed.
he loves fixing stuff that aint broke until it breaks.
I used Redline Shock Proof Gear oil in my Harley Transmission....worked well. Bought a 2018 5.7 with 44k miles. Nice and quiet until the other day....heard the dreaded lifter tick on a warm restart on level ground! Damn...first thing went thru my mind was OIL CHANGE! So I will try the Red juice and let you all know how I likes it.
