I have a customers truck we have worked on since new that has 687,800 and change. It is an oil field gauging truck we've replaced 3 transmissions countless fuel pumps and the posi trac fragged and destroyed the stock rear end. But the motor has never been into before and still runs like a top and does not use a drop of oil. It has had chevron delo 15w40 diesel oil in it since new.

My truck has 323,000 miles on it and still runs like a champ. Was planning to replace the engine by now but I guess i will have to wait longer this thing wont die.
