I would think twice before I would get the pac-car engine. It is new to this country and from what I understand the problem is parts availibility.

Then think about if you break down or when you break down, the only place to go is a pac-car dealer. That could create a bigger problem or a huge tow bill.

Detroit and cummings have a much bigger choice of service areas. With Cat gone these are the only 2 I would choose from. Just my opinion

That's true Cummins had problems and I am sure they still do but the company is have so many problems with the Paccar engine that the solo drivers with the cummins engines is getting more miles in a month than the teams do with the Paccar engines so there broke down a lot.

by Mel

Well I took my own advice got rid of that worthless Detroit and bought 2011 Pete with a ISX cummins and just loving it is the dependability And fuel mileage great and the jake brake is great right up there with cats brake saver system

Ditto! I can easily out-pull AJ at Stoller Trucking when we both go up hill. But on flat land and downhills, he's just a tad faster. I have a stock 3406E (5EK, 375 HP). He has the PACCAR MX. Once I get Pittsburgh Power (and Disc brakes in order to slow/stop the future beast I plan on making out of my current truck after I buy it)... Yes, I am considering turning my truck into a Glider (since Volvo doesn't really support the WIA anymore).

Paccar is not a Cummins motor (DAF/ISX 15L). Best bet is to stop by a few KW and Pete dealerships and ask the techs about issues with the MX engines they come across.

I'd wait until the bugs get worked out (which could be 2014 at the earliest) before investing in the PACCAR MX. I haven't heard very much about it, but I think stopping by a Pete or KW dealer and asking the shop is a great idea to get insight on the engine and it's issues.

Also, don't overlook the option of keeping your existing engine and having a Glider Kit built. You'll probably be happier with a Glider than you will be with the MX.

If you MUST get a SCR or EGR engine, I would consider a Freightliner with the Detroit DD-series (DD13, DD15, DD15 TC, DD16) or something with a Cummins ISX as alternatives.

I like the DD-15 better than my current Paccar MX. But I haven't had major problems with the MX...yet. So far, regular maintenance and a handful of check engine lights related to software issues. The truck has 301,000 miles, and I've put the last 171,000 on it.

I would think long and hard about buying a Paccar engine, there are 50 Peterbilts, 2012 models sitting at KW, VanBuren, Arkansas. The company traded them in on 2013 KW's w/ Cummins engines, they couldn't keep them {Paccar} running!!!

And there is a fleet near where I live that kicked Cummins out the door for Paccar, for the same reason. Neither one are worth a !@#$!

by Your

They are BOTH terrible! I would go with a Freightliner Cascadia with a Detroit DD15 instead of the PACCAR products if the company is having trouble with both the PACCAR MX and Cummins ISX. It's too bad the Detroit engines aren't offered on Peterbilt and KW anymore.

by Zachary

If I could get a DD15 in a KW or Pete, I probably would have already bought one. Detroit makes a better engine, but Paccar makes better trucks.

Our Government is allowing mergers and purchases that are not in the general public's best interest, I am alluding to Detroit Diesel being sold to the company that owns Freightliner, Pilot taking over Flying J, Sirius and Xm merging, I'm sure that there are others that I can recall but even though Detroit Diesel is owned by Freightliner, they should "have" to sell engines to other truck manufacturers!! Once I fueled nearly 100 percent at Flying J, since Pilot, I don't even go into their facilities!!

Detroit Diesel was not originally bought out by Freightliner. It was a part of the Chrlysler group and when Diamler sold Chrysler they kept Detroit Diesel and made it a part of the Freightliner group. The company was struggling and the Mercedes engineers and marketing gurus turned it around. They brought the Blutec system to the class 8 market, and it is now the most reliable SCR system available. That was a definate positive to the general public's interest. I'm sure that if another company wanted to use Detroit engines they would be able to negotiate a deal. However, most other companies have chosen to use their own engine platforms. International didn't offer anything but their own engines for a couple of years. They refused to put any SCR technology in their trucks. When they were forced to, they made a deal with Cummins, now both engines are offered.

by Your

Actually Detroit was first owned by General Motors corp who sold it to Roger Penske. He along with John Deer brought the series 60 to production. Suddenly it was the best engine on the road and everyone knew it. It was for several years the "power of choice". Diamler bought it who already had a stake in freightliner and frankly was bought to "shut out the competition",it sent freightliner sales thru the roof. I worked for Detroit when the 60 series was being developed, we all laughed and said it would be crap till they worked out all the bugs.....boy we where wrong.

Yall dont forget about the Mack mp8. My KY tech tells me no work from warranty with them and thats a good sign. They seem to have all the bugs worked out. Plus they are rock solid on the road and very well built. I am waiting for a secondhand pinnacle with the M-drive to hit the market but alas there are none being traded in yet.

That tells me the Mack MP8, also known as the Volvo D13, seems to have had the bugs worked out. That is a very good sign and I am seeing confirmation of that on other forums (truckers report, etc...). Then again, I wonder why PACCAR and NAVISTAR were so late to the game... They, like MACK, VOLVO and Freightliner, should have been getting a head start on this back in the late 90s and early 2000s. Volvo's D12 had (and still has) problems with EGR and Volvo figured out they needed to add a liter of displacement along with a redesign, hence the D13 and Mack MP8. Freightliner/Mercedes/Detroit Diesel also figured they needed to re-design their EGR engine early on, and up the displacement from 14L to 15L. They chose to do an all-new platform for both Europe and the US at the same time. Ditto for the red top (Cummins) who came out with the ISX line.

i am currently doing my research on purchasing a 2014 and have been trying to decide between the dd15 evo and the mx13 pac car. i am with schneider so i am getting a lot of feedback from owners of both as well as several shops at our o.c's, the fuel mileage on the evo is pretty much all coming in at 8.1 and above with 10 speed tranny and 2.24 rears. the mx13 is coming in at 7.65 and above but the specs are the issue there they are running the 13 speed tranny with 3.36 rears. every shop guy i have talked to says they would nearly put it in writing that i could achieve competitive mpg by simply correcting the rears in the kw t680. that said they are seeing a lot of cam housing problems with the mx13 however kw is on top of it and allowing schneider shops to do the warranty work so as to help reduce downtime. also the job requires only about 10 to 12 hours to complete, with no issues after the fix has been made, not all the mx13's have this issue either.as for pricing well im looking at 2014 turn in truck both have less than 25.000 miles on them and both are going for 125,000 but due to my longevity and the fact i have paid off 2 trucks ahead of the contract they have actually offered me a track matching program which means every dollar i put toward the principal above my normal pymt, they will match 1 for 1. with no limit on how much i put into that program could be a substantial discount the overall price of the truck. has anyone got any calculted mpg numbers on the mx13 they are driving. thx for any input, mike m

gun to my head dd15 evo with a 13 speed.more options for shifting than a 10 speed.2.24?too high.kevin talks about 2.64 or 2.79 for running in 11th.a 10 speed,i would think is undriveable with 2.24.i like 3.55 and use all 13 gears though at 55 in 11th is optimum

Whose ever herd of a paccar engine five years ago? Exactly! New engine with

a set of new problems for everybody. This engine is new to the American

trucking industry and many mechanics and shops don't have the tools or software

to deal with this engine. You must go to a certified Paccar dealer and hope

for them to fix the problem. My advice go with the known brands like Cummins

or Detroit too bad for CAT they are out of the bizz. Cummins would be my first

choice. Plus have you ever seen a paccar engine it looks like a freakin yet

engine.

If you have any dealings with Peterbilt and their mechanics. Go talk to a few of them about this engine, all I have heard about these engines is on the negative side. I would not take a chance on getting burned buying one of these engines.

The Paccar engine may have had some problems at first, but the 2013 model engine is a lot better they fixed the fuel system problem and the are running right with the cummins ISX. 2 major things to know is: 1 yes not every shop can work on them, but if you have a kenworth or peterbilt where ever you go you can get them fixed. A lot more little shops are getting certified too. 2 they are a 13 liter engine, but they are still putting out 500 hp and getting better fuel mileage.

40% of the new peterbilts come with Paccar engines and that number grows very year. Paccar is going to be the 500 hp and lower engine in the future and possibly more hp.
