I don't know if it makes me feel better, but I'm more so curious as to if this helps. I love my diesel. A lot. I just want to make sure it lasts as long as possible since it seems that most people who drive a modern diesel vehicle (less than 5 years old) complains about the low lubricity of US diesel fuel. Go figure.
