hi, well let me update you guys.
i have a 1986 300zx with some sludge..oil never been changed for a year or so. so i tried auto rx (4 months ago) but i never got more than 15 miles in 5 months. well in the last week i put over 400 miles on the car .now that 600 miles have gone i just want to change the oil.
i took a look at the dipstick and its pretty clean..slightly brown...but then i drained a little oil into a clear cup and it came out black!
could all of the sludge dissolved and accumulated to the bottom...is this why i see clean oil on the dipstick...i know this sucker got cleaned though..inside most of the sludge is gone...
i just want to know how is this happening...curiosity..this car itself is a suspision...
excuse the spelling.
