New 2007 2500 SLT

I gave mine 7,500 to get seated.

No expect. Change it every 7,500 miles, and your truck will last longer.

The new '07s are required to run on ULS, and will damage if run with regular diesel. Not so with '06es. They will run with either. For about four months now, ULS is all I have seen at the pumps, so the old stuff is apparently being phased out fast. BUT WATCH THE PUMP LABEL AND DON'T PUT THAT OLD STUFF IN THERE, OR YOU COULD HAVE PROBLEMS IF YOU GET ANY OF THE OLD STUFF. I don't know what the cut off date for selling ONLY ULS.

Just watch the engine while it's breaking in. Oil leaks, driveway spotting, usual stuff. Keep an eye on the oil level. Air filter is easy to check. Drain the water from your fuel filter, especially if you live in a humid area. (in the manual, real easy)

Oh, one more thing. There's lots of helpful info in that little book in the glove box.

tow with her right away without fear...its a Cummins she's happiest loaded.

i done my first at 6000 you could wait till 7500 if ya wanted.

the regular service interval for the Cummins is 7500 miles.

ulsd is required by law on highway service vehicles in the U.S.

Keep your oil changed (every 7500 and fuel filters every 15,000) yer good to go.

IIRC, about 500 miles is the most 'easy' driving you should do, and that is if you fear doing what Chris just suggested. If you break in your CTD while loaded (under load, not drunk), it will seat everything quicker and better. Drive it like you stole it.

As far as ULSD, I know it is supposed to be used in the 6.7 but the last

Filter changes: make Geno's your friend.

Yeah, watch for slow traffic while going uphill.

I'd go 250 miles just to get things started. Then load the hell out of the truck, pull a couple of cars and a boat all at the same time if you are so inclined. Loading helps seat the rings. If you don't load the engine, it'll take years to fully break it in.

No, I'm not exaggerating.

thanks everyone

I will go for a few looooong drives then drop the TT on it and go to the mountains next weekend.

I really appreciate the opions. Hopefully Tuesday night I have a brand new manual to read (along with the truck)

Hook up the trailer and go. just keep an eye on your fluids and temps and you'll be ok. the electronics that control the engine will take care of business if there's a problem.

I maintain a nationwide fleet of trucks.. an engine like yours would see its first oil change in the 6000-8000 mile range. most new trucks will hit the road and not be seen again until their next pm service. I doubt very much the people who rent/lease any of these trucks are concerned about the actual breakin.. they just load them up and run the bag out of them.

in the states all you're going to get is low sulfur unless your buy fuel that's for off road use. More than likely you won't find it at a fuel station. the engine in your truck was designed to work with the low sulfur fuel.

It's hard to find low sulpher diesel fuel in the Atlanta area. They started switching over to ultra low sulpher about 6 months ago. One concern of mine is for the guys that must use ULSD. What happens when a station switches over from LSD (the fuel, not the drug) to ULSD? Do they empty the storage tank completely before getting a ULSD shipment? Can they dump 500 gallons of ULSD into a 250,000 gallon tank half full of LSD and sell it as ULSD? How does the customer know for sure? If something like that happens and it causes engine damage, how can the customer prove which station he bought the mislabled tank of fuel from? My '99 CTD is giving me a bit of trouble right now but I won't even consider replacing it with a new one for a few more years.

Something tells me that they have to pump the old stuff out first.

UPDATE thanks everyone. I have read the manual front to back and took in to account what everyone said. We drove it 800KM before we dropped the TT on it. We then stuck to 80 KPH or 50 MPH the whole way to Banff and back this weekend.

What a blast ! This is the first time in 30 years of driving that road that I never noticed the hills or steep grades. This thing just ran up the grades and never even changed gears. We also used 1/2 the fuel of the 04 Hemi.

Dealer said that 7500 to 8000 KM will be when to change the first oil.

Turns out we only have ULSD in the Calgary area. Selling for .80 / litre at the local Flying J. That is somewhwere around 3.03 / gallon US. Unleaded is going for 4.58 / gallon.

What a beautiful area to break in the CTD. We were there 2 years ago with ours. Yeah, driving it for the first trip is a blast. It will continue. Congrats on your successful trip.
