Towing Break in?

[HBarlow]

Patty,

Welcome to TDR. I didn't notice it was your first post when I responded.

Even correctly quoting the owner's manual, properly understanding it, explaining accurately, and being in agreement with 95% of members doesn't mean someone here won't argue about it.

run it hard

Some of the first Cummins B Series to be used in Pickup Trucks was for Jet Transport, Middlebury, Indiana.

Cummins worked with them supplying engines, they were mostly put in Chevy pickups. They ran them hard and long hauling Jaco RV's all over the USA, Canada, and to Alaska.

Dodge tried the Mitsubishi Diesel engine then hooked up with Cummins.

A very good move for sure!!!Oo.



Run it like ya stole it!!!!!!!!!! :-laf

IIRC, there was an article about that in either Issue 1 or Issue 2 of the TDR magazine.

JET has some old photos on the walls in their lobby.

Years ago they used company trucks and drivers to deliver their trailers and after wearing out a few Chevy engines they installed the Cummins engines in the Chevy chassis.

Jet

HB,

Yes, I have seen the pics, talked to some of the mechanics that worked on the pickups etc. , I had one of them change out the head gasket on my engine.

I worked with JET for about a year, that was over 10 years ago.

Those guys knew a lot about the mighty B Series Cummins, fer sure!! :-laf

Guess I really sqewed up. I hooked up my car trailer loaded at 300

miles and didn't stop until I reached 6500 miles. Then changed the oil

and filter. So far so good at 18,000 miles.

No you did fine break it in the same way you drive it

It's not bad, just not the ideal way to break in the drivetrain. . the motor loved it! Thou personally I would never go 6500 miles on the first oil change, especially on an EGR motor.

What does the EGR have to do with oil changes?

 

[Grizzly]

I believe the best way to break-in a new Dodge/Cummins, after the first 500 to 1000 miles, is to hook up your 5th wheel and tow it to Alaska and back. That's what I did with my 95. My 05 had about 3000 miles on it when we made the 2nd trip to Alaska. I did change oil and filters for the return trips from Alaska.

Recirculating exhaust gas into the cylinders introduces soot which is washed down the cylinder walls into the oil. The regeneration cycle on the 6. 7L Cummins also uses a late fuel injection event to build heat in the exhaust emissions converters and filters - this late injection event results in fuel dilution of the oil. So, by design, there's far more soot and diesel fuel getting into the oil with these engines than with the older 5. 9Ls.

Exactly what Grizzly and RustyJC said, and compound that with a new motor where the rings aren't fully seated and they make some nasty oil for the first few thousand miles.

The amount of recycled exhaust returned to the combustion cycle is very small, if the truck is worked as designed there will be none to little soot, my 2012 has cleaner oil in it after 5000 miles than my old 2005 5. 9 had at 5000 miles, that small amount of exhaust sent back into the engine doesn't make oil get dirty.

 

[RustyJC]

Ummmm... . OK. Whatever you want to believe.

Nope, no soot at all.

Your signature is a little ambiguous- is the "CC" crew cab or cab and chassis? If it's the latter, that truck has a different emissions control system that the PU and used a lot less EGR.



EGR is a scourge to diesel engines. You should see what it can do to an old Mercedes or a VW TDI. The tree huggers could have air almost as clean without it and diesel owners (and manufacturers) would have a much easier and more economical life.

Pretty sure he didn't say no soot, just less.



An oil analysis would positively settle the question, control of the parameters might be a little hard to achieve on two trucks but it could be considered close enough for viable results.



The difference between an exterrnal magaed EGR and the constant in-cylinder EGR is huge. EGR is only circulated when it deemed needed instead of constantly being in the cylinder thru valve timing. By its definition and implementation, soot loading in the oil is going to be less with managed EGR.

When I left the dealer with my new truck I drove 55 MPH I hit I64 in about 13 miles then ran it up to 110 then down to 70 then 110 70 110 then 70 all the way home. Hooked up to my fifth wheel at 300miles went to south TX then to CA then back to IN after being on the road for 6 month.

 

[Cummins12V98]

I am jealous! 110, I can only get 104 out of mine. Picked mine up from Dave Smith and headed west on 90 over the pass. Going up the pass I poured the coal to it up to 95 then going down the hills I would let off. I keep the tow haul and e brake on all the time.
