My '06 is a pretty good truck.

I average 16mpg. Highest tank of 20.7, lowest of 12.2. It is my DD in DFW metro. Think high temps and stop 'n go driving w/ interspersed freeway. There was also a tire size change in there too

I take my oil changes to 7500mi. And I do an oil analysis with each. They all show a great internal condition for the engine. I use Fleetguard 16035 oil filter and one of three 15w40 oils (Mobil Delvac, Valvoline Premium Blue or Rotella). I change the stock can fuel filter every 10k (Baldwin PF7977) and I have a 2mic aux filter after that that I have marked for either 10 or 15k (Cat 1R-0750 or Donaldson P551313).

I run with the tranny in T/H mode. I like the shifts better. I haven't hauled heavier than a bed load of mesquite firewood for a 420mi trip so I can't comment on towing. But I think that was the smoothest drive I've ever had

When I first started searching for a Cummins I remember having the question "Which year?". I wanted something low mileage and a 5.9. The best shot at that criteria was an 06-07. It just so happened I found an '06 w/32k for the right price. It was the right truck. I currently have 65k on my truck and it's been paid off for more than a year now. Value has appreciated. And I ain't getting rid of it for nothing

 

Yup, in cylinder EGR dirties up the oil immediately with soot, "insolubles" as they are called on the oil analysis. Run a good filter and a good oil and the color of the oil doesn't matter, just the content.

You can extend oil change intervals with an oil bypass system. The added oil capacity and secondary oil filter aids longevity. But on the stock system, like I said I'm going 7500mi and according to my OAs I could be taking them out longer than that. So, you have a good bit of room on an oil change permitting you monitor with OAs to forecast.

 

Well after many emails asking for pictures of the bed inside and the underside of the truck (a long story here, but no time to explain), they finally pulled up the plastic bedliner (which to me is always a red flag to me...a used truck with a new liner.), and told me the bed was really beat, with depressions between every bed crossmember.
Too bad...it "looks" like a beautiful truck, you can find it at Strumburg (sp?) in Jasper Indiana.
SO, I'm still looking...

 

I have a 2006 5.9 cummins 2500 with 80,000, last 40,000 have pulled a 10K fifth wheel. ST exhaust, A&e intake, no chip. It has performed quite well, only problem has been a blown water pump, and new batteries. I plan to install heavier rear springs to compensate for a new trailer which will add 400# to payload. Other than that, all is well.

Does anyone have comments on exceeding factory payload specs by 1300 lbs??

 

I'm sure that's been done alot with these trucks.

Getting it moving isn't the problem, stopping it is.

 

texexjim I put firestone air bags on my truck and they work great, run 10 lbs in them empty and 25 lbs with my 5th wheel hooked up, no sag at all, rides nice,

 

^^^I second the airbags, more cost effective than heavier springs. Plus you can air them down for comfort when driving empty.

 

^^^^ Third on the airbags, you will love them.



The biggest issue is the recirc door breaking.

Also check the steering gearbox, the one in my '06 failed at 48k miles and was covered under the 5/50 per my dealer.
