Paccar MX Engine Then & Now - Purchasing A Pre-Owned Truck With A Paccar MX Engine

[@chazarkansas1366]

Today on Paccar employee says Paccar engine is the best.

Mx certified diesel tech here. 75k oil changes... Keep doing that... Please... Keeps me and my coworkers busy!

[@daneblackburn613]

Haha

[@dankruger2890]

Ya, try 55,000 mile oil changes. and if you idles 40,000 mile oil changes

No oil lasts that long. You want your engine to last. Change the oil, OFTEN

[@yahtotv5492]

Well my time driving for a company that has over 7000 trucks. The Paccar trucks with the MX engine spent far more time in the shop vs. the Cascadia with DD engines. And the Detroit engines always topped the fleet every week in fuel mileage. And they ran all their trucks 75k between oil changes.

[@CharterTrucks]

No doubt the Detroit DD series engine is one of the best engines on the market today.

[@chestergerber7125]

Well..imo 50 60 years ago and back, there were zero million mile engines. Even the old Mack 237s and 300s wouldn’t bump 1 million. Then Detroit came out with the 60series, Cat also improving longevity with the 3406 on to the C15s. Cummins had the N14s which also lasted a million miles. Now we are reverting back to low mileage longevity. I will be driving 50 years in June and owned my own truck since 1979. That doesn’t mean I think I know it all, as I do not. But I have used and put many miles on some of these older engines. Also have sold them to someone and visited with them later, of course trucking comes up and I ask how is my old truck doing? Doing good seldom in the shop or never. Fleets are where the $ is selling trucks and engines. Big fleets dump their trucks at around 400 to 600,000 miles. Just when the engine especially Paccar or X-15s are ready to die. That 75,000 mile oil change is ridiculous. So now large fleets won’t grease or lube the truck but maybe every 75,000 miles. Looking at newer used trucks for sale, high mileage ones are generally deleted 😮, then I see many with an in frame usually before 600,000 miles or a complete engine replacement. I may add that low miles on an engine replacement or warranty usually requires many repairs to create a track record on that engine, or catastrophic failure. (equating to many shop visits and downtime )Who knows how many times that truck was in the shop while accumulating the 600,000 or less miles.

The DAF MX-13 engine which is named after the mother of DAF: PACCAR. DAF is an industry as well Kenworth and Peterbilt. PACCAR is the mother of the three.

Love mine!

[@Trucker_Raven.8906]

75,000 between oil changes 😧 Seem like a lot to me 🥴

[@fabianpachoek7731]

Europe loving my 13 in daf

[@Jackknife-TV]

Constant emission problems and electrical problems..... 90% of it is dealer only service/parts .... you could buy a $10,000 Davie System and the $1,200 subscription fee if you really want to get technical I guess it might pay off if you have a fleet of 100 mx13 engines.

[@zacharybishop6595]

Not a truck driver but I like the throaty sound of the Paccar, reminds me of the Volvo D13

[@scubascubadew]

You spoke about keeping idle time low. You also spoke of the advantage for bulk drivers using the MX engine. Some Bulk drivers have PTO's and have high idle time to load and unload. So I guess MX is really not good for Bulk Drivers?? Confused?

[@CharterTrucks]

Kerry, that does seem like a contradiction and is an excellent question. I will try to get an answer for you. Take care.

[@CharterTrucks]

Hi Kerry, thanks for the question. It is a good one. As with all the new engines, idle time creates issues by not generating enough heat, which causes issues with the dpf filter. When running a PTO unit, in most cases the truck idles at a much higher RPM and temperature, so it does not create the same issue, as when you sit and idle. I hope this helps. Take care.

[@arcticfox5118]

I own an end dump with a MX13 in her. The trick here is to service the EGR and def system every 6 months and replace the sensors on a yearly schedule i.e nox/quality sensors as a lot of idle seems to cook them. Also you cant let PMs slide past 25k either as it seems to cause a lot of issues. This means the cost of maintaince and down time average out to around 20K a year by comparison the cats owned by the company are only 5-15K. BUT the cats average 4.5 mpg over 120k miles per year. My MX13 averages 6.5 mpg per 120k. So the company trucks cost $100k or so a year while mine is 65-70K a year which more then offsets the higher maintaince cost. That said id still rather have an ISX or X15 as the MX13 is underpowered for MY job it does NOT like 85500-105K loads and the motor is pretty weak on pulling hills. Good jake though. That being said of they make a 550-600 HP 2050-2150 torque rated 15 liter engine id consider one. My MX13 had 700k and im fairly happy with it.

[@bormanaj]

We’ve got 3 500hp mx-13s and 2/3 have had a catastrophic failure before making it past 750,000 KM. The third one is now strictly on local runs and no longer runs any further than from one location to the next (all within 150km of each other) because it’s a ticking time bomb. All 3 of those trucks were driven by the best drivers we have that really treat their trucks well. 1 punched a valve thru the head and the other slung a rod and ended up burning the engine bay up... not overly impressed with the mx-13s. The rest of the paccar trucks are 510hp, and it seems they’re always in the shop for egr valves and turbo actuators. Not to mention their plastic oil pans have ALL warped (to the point you can visually see the warp in the rear P/S corner when the pan is sitting on the floor and you’re standing 6 ft away from it) and some of them ended up damaging the block in the process. Not impressed with these engines. Edit- all our paccar trucks are 2015+, for those I saw wondering if the newer paccars are better, they’re not.

[@CharterTrucks]

Thank you for your detailed and objective analysis.

[@dankruger2890]

My brother doesn't like the 2011-2014 mx13 and he drives for a union food delivery company with a large fleet and they wont buy Paccar's any more but love the newer cummins. Maybe the Paccar has changed alot in the last 5 years. ISX had problems back in the day 11'-15'

[@CharterTrucks]

I think Paccar like Cummins has improved the treatment systems over the last five years and both seem to be performing much better.

[@moparjr89]

The new x15 eats cams like the isx

[@Trucker_Raven.8906]

@@moparjr89 Yea I heard about that.

[@samirkasimov4934]

Both engines are good , Cummins and Paccar have improved a lot. Depends what you want, if you want power choose Cummins if you want fuel economy choose Paccar

[@adammcphee1795]

I'd love to know how much these guys are paid to talk up the paccars

Ha, not quite. Camera Crew is there as well.

[@jerseycowboy1]

All these newer engines are failing around the warranty expiration date, 500,000 miles. A company don't run trucks to 1 million miles. They sell them just under the 500,000 mark before they are ready to cause major repairs.

Major turn off cost of parts..

[@kevincarter5854]

How many miles will Paccar warranty their engine, if they think it will go 1 million miles then warranty it for that and only require 75k oil changes, proof is in the pudding just look at all the reviews online about problems problems problems and I know companies that will no longer buy a truck with a Paccar engine , proof is in the pudding.

[@Dewey_Boondye420]

they warranty to 750k miles now or 7year.
