I've been doing regular UOAs on our MT665B Challenger tractor. Tractor has a Sisu 8.4L engine. Tractor is used almost exclusively to pull our 30', tri-axle manure spreader. The previous two UOAs were with Service Pro 15w-40 CI-4+ whereas the most recent was with Service Pro CJ-4. Tractor currently has 3388 hours. Engine is equipped with a centrifugal bypass filter which was part of manufacturers recall. If not listed its a 0.

I was impressed by the reduction in soot. Does the formulation of a CJ-4 oil allow the soot to filtered out easier? This oil change I used Mobil Delvac 1300 which I got for like $6 a gallon after mail-in-rebate. Might try and push OCI to 400-450 hours.
