All we run on every motor Is a NAPA GOLD made by WIX or a WIX. Big power Diesels and many big HP motors built by my son at the machine shop
My Duster spins to over 8000 evey time out Rev set to 9000, 6 years 5500 stall 456 gears runs hot and still running strong. Members on here have been in it on the street. Pegs the pressure when cold. Factory spare still in trunk. Heavy car. Cut my filters every change never a defect ,
Sorry that you must have bought the only bad one made. Notice they don't sell WIX at Auto Zone. And you have to ask for gold at NAPA. double the price ????
I would never put anything else on my motor. Or a motor built here.
