When we bought our coach, 09-04, the engine had 4,000 miles on it. When I got it home I changed the oil. Within 300-400 miles the oil was very dark. I have always changed the oil every 3,000 miles. Everytime it is dark in 300 miles. I have used dino, Rotella synthetic, and last of all Mobil 1. Everyone of them was blackened within 3-400 miles. No one could tell me why. Engine was strong and did not smoke out the tail pipe.
The compression ring was gone on number 2 piston and the groove was in bad shape. I am thinking that this ring may very well have been broken when I got the coach and caused it to let the oil get black in a hurry. What do yall think?
