Car has used 4.5 quarts of oil and that was to 9,000 miles at which time I changed the oil and used Rotella regular 15-40 diesel rated oil. The last 1,000 miles to reach 10,000 miles, the oil is basically holding steady and I haven't added any oil and it stills registers basically full at the top of the oil dip stick. The big bolt above the water pump leaks a little and account for some of the small usage. The car runs better and better every day up until today. I don't know what it will do tormorrow, but it seems to make a sweet screaming sound when I step on it a little. Except for some on start up, the blue oil smoke is gone as noticed when driving behind the car. It's the other issues that have been getting me lately. The door locks went out, the A/C went out, glow plug lights came on. Cruise control kicks in when it gets ready. But as long as I can continue to forget how much oil I have used and have to go back to the books to add it up, the car is fine with me. I used to know that when I drove 200 miles, I was one quart low, which was very easy to keep track of and was fresh on my memory every day I drove the car. I'll know more at my next oil change in 5,000 to 6,500 miles. Now, I just need to figure out how to get some of my money back from having mastered this car as of today and am still working on solving a few other experiments to better understand this beast of a car, the 140 diesel.
