3.73 non-ls
Finally got around to popping the pumpkin open and changing the fluid. It is so much quieter now but I can still hear a little bit of whining when the rear window is down. It is not loud (anymore). I am assuming this is typical? Would a heavier oil quiet it down more? I used Mobil1 75w-90LS.
I used a LubeLocker gasket so have no problem opening it back up and putting in 75w-140 if it will help. Thanks.
Edit:
The old oil was nasty, almost milky. Not much on the filler plug magnet but it was caked with a white, milky sludge. As far as I know it had never been serviced before.
