This was 5qts of M1 5w-30 and 1qt of M1 10w-30 along with 4 ozs of Redline Break in additive. The filter was Carquest blue(WIX) 85516(51516), oversize for this application. The engine is a 3rz-fe(2.7). The truck is a 4x4 and is taken off road occasionally. And I pretty much drive it like I stole it. This is the first UOA on this vehicle and given the results I plan on switching to once a year OCI's. The oil was in service for approximately 8 months.
