189,000 miles?
That engine has been well taken care of for heavy towing...low contaminates.
Moly 78. I see you added 1/2 quart, was that at the end of your change interval?
I have 2 5qt jugs of Pennzoil Platinum that are going back to walmart since their rebate didn't go through. I'll be going back to Mobil 1 in our vehicles but probably 0w30 for the winter. Should have never thought about changing brands of oil to begin with.
Good numbers on your report! Off to walmart and the NAPA parts store.
