Anyway, I want to add the MMO to the Low Ash 30 wt. in the crankcase. The tractor has always been run on the IH LA oil. I only have 16 oz. of MMO left in the bottle. Please tell me how much to add to the mix.
Thanks

Mike, sludge in the drain line is not unusual. Since there is no circulation in the tube, the heavy stuff that passes over the opening just settles out there.
As far as how much MMO to add to your oil, check the container. There should be recommended amounts listed if I remember right.
