So, I have developed a new oil change procedure that will enhance the cleanliness of your engine oil. Soon to be a DC TSB!!!
- Drain oil
-Change filter (prefilled of course)
-Fill with 16 Q new oil
-Run 30 sec
-Drain 5 Q out via oil pan drain plug
-add 1 Q to top off
I think using this procedure will drastically reduce the engine wear
associated with used oil contamination... ...
Of course you all realize... that if I was stupid enough to put 4 gals of oil in
during my oil change, I would have to do the same thing!!! :-laf
