I have about 200 miles on my new 2500 sb quad cb 2002 auto,cummings 24V 3.55 gears<br>what is the best way to break it in. how many miles to break it in. what can you do to get the ulmate fuel milage from it<br>Thank you, Alan

Change oil @ 2000miles the first time<br>Fill the bed with rocks and put a heavy trailer on it and <br>start towing and in about 20k you`ll almost be broken in. and <br>the milage will start to come up.<br> Danny
