Next week my 04.5 3500 4x4 QC lwb CTD will arrive!!! Can't wait...This is my first Cummins and I have already planned my first trip. From Rhode Island to Tampa Fla. ( two days after delivery).My question is, How would all you Diesel heads break in the motor? RPM range Speed ect...

 

I asked the guy who delivered mine about break in. He said "Don't get crazy with the towing." I said I have a 13k trailer that I want to take on a 650 mile trip up to 8500 ft and back. He said "no problem, that's how you break them in." Of my first 5k about 4k was towing my trailer. I picked up about .5 to 1 mpg on each of my first trips. I spent over $550 on diesel in August alone.

 

Thanks zzsdad

 

vary your speed limit on the highway....60/65/70...do an hour at each and restart at 60....Front of owners manual will tell you the same thing....
Oh go down through Delaware on 13 S and across the Bay Bridge Tunnel through Norfolk....It'll cut 3-4 hours off of drive by bypassing Baltimore and Washington, but cost $10 to go across. After crossing the tunnel and coming into Norfolk, look for signs saying Chespeake/Portsmouth/Suffolk and head that way onto HWY 58 until you hit 95 again....Look at a map first...it's easy to go the wrong way around Norfolk and end up heading back toward RIchmond....

Good Luck...and enjoy the ride...

 

Check your manual. Mine says no towing 1st 500 miles, then stay under 80mph if towing for the next 500 miles. Enjoy your new Cummins. Get some photos up.

 

thanks for the info folks. I wonder what a diesel sounds like in a tunnel!!!!!
