mickey_rubicon said:I have been using the 80 dash 90 from Valvoline by the 5 gallon bucket and it stays clean and gets changed every 10 to 20 thousand miles depending on if I think I sucked any md into the center case. My budget is too tight for synthetic gear lube. But at 219 K miles I don't have any problems with any of the pumpkins.
When I opened the case I did notice a blackish gray greasy film on most of the non moving parts.I can imagine if your oil was bad for long time there will be deposit there that will get washed by new oil, especially Mobil that tends to work as the solvent. You may want to change again soon just to check.
Instead of using all Mobil try make few changes with one can of Mobil and the rest NAPA oil which is $3.99. often changes should wash your gunk out.
Yea you will always get gunk whereWhen I opened the case I did notice a blackish gray greasy film on most of the non moving parts.
