I have had the dealer change my oil the last 2 times is this something they can do? How do you get sample bottle or where do you get them? Any help on this would be nice since it sounds like thats the key to keeping everything in check on this diesel. Any other advice

 

You can probably give a bottle to the Ford dealer and he can get you a sample of the oil.
If you go to Blacksone website they will send you testing bottles for free.
