[Questions] DD13 Vs D13 - Which One and What should I look out for?

I like the DD engines , the DD13 is more fuel efficient than DD15 . I would pull a DDEC report off the computer , also have the def systems hooked up to computer and run it thru a regen . You will also find out how much filter life is left once you run it through regen and the tech can pull the stats . Idle time is important , a truck with out apu is gonna have high idle hrs and is considered severe duty and should have had frequent pm service do to the added run time . Oil samples dyno if possible. Oil psi should be at 50 psi or above at 1500 rpms around 65mph give or take . Check color of coolant resivoir for any discoloration , oil or soot in Reservoir means blown egr cooler or oil cooler.
Basically have it thoroughly gone through and even than you could hit a brick wall months later .

 

I'm a Volvo fan and love my 2015 D13 (780) but in your shoes I'd probably go for the Freightliner if the rest of the truck is what you're looking for. Volvos can need Volvo dealer specific maintenance and you might want to live close to a good dealer or shop who can work on it.

That said, mine has never put me on the side of the road in 300k miles. I'm at 832k on mine and running like a champ. Just regular maintenance. None of these trucks are maintenance free.

 

Considering both are getting close to needing some pricy emission system maintenance, the Volvo for $10k less looks pretty tempting. This is assuming both trucks are in similar mechanical condition.

That's just my $0.02 though.

 

If the Volvo has not had injector cups at 589k it’s probably not far from needing them. Which isn’t a huge deal, especially if you use a reputable shop that isn’t a dealer. But something to consider. Either one are to the point the emissions systems could be really problematic especially if they haven’t been maintained correctly. I personally lean Volvo, I’ve always had better luck with them than the DD’s myself. But whichever you choose make sure you have it thoroughly gone thru, oil samples, dyno etc. And be prepared for a potential pricy repair regardless

 

If this helps my Volvo still hasn’t had injectors or cups at 830k. It has an APU and I don’t idle it ever for more than 30 minutes.

 

The 16 dd15 i drove got better then the 12 dd13 i drove. More power too.

 

Wrong quote. That was for @danny23tx

Sorry @86scotty

 

Don't you think it depends on the loads you carry? My 1st truck was a lightweight Cascadia with a D13 and I swear when I got the DD15 full-size truck with the auto I was getting better MPG. (both had the auto's btw)

I could see the DD13 being better if you're mostly light but if you carry heavy a lot I think the DD15 strains less and does better.
