    Hello my man, well the fact is I'm back home and I'm currently driving an 2010 mx in a daf cf car transporter, guess what? 4 litres of water a day and a gallon of oil every 4-5 days, there has also been injector issues, now in fairness the truck is double shifted so miles are clocking up fast, they are treated rough but the mercs, volvos and scanias in the fleet are not having the same issues, I'm not misleading anybody I'm recounting my experience which started in 2003 and continues to this day, I have no faith in these engines, they have improved but are far from a great engine, certainly not a million miler ! liners and pistons don't seem to wear out as quick but they still have plenty of other problems. Detroits and cummins have major problems with egr etc but paccar are bad engines from the core.

    Scaniaman,you rule,you are the best.
    You are the only person i know who comes on a forum to complain about a engine based on his experiences with that engine which you bought
    3 years before that engine went on sale.

    Because what you fail to mention is that the fact you bought those trucks in 2003 while the first MX only went on sale in 2006.:yes2557:

    Like Sebas said,stop telling lies.
    All you are doing is making yourself look like a fool.

    Yes fangio I know the ones I owned in 2003 weren't mx but they were still paccar engines and as far as I'm concerned things haven't improved much since the introduction of the mx as I can vouch for now with the MX I'm currently driving, ok the oil burning problem seems to have been cured on newer models of the mx but injector and cam problems are rife, how's your paccar mx engine going since it was rebuilt? The mx I'm driving still uses oil and water to beat the band but I doubt it has the newer improved rings and liners like you had to get in yours, bloody shame to see a new engine being rebuilt , but hey as long as they fixed some of the issues eh? The point is wether it's the mx or it's predecessor daf/paccar haven't built a decent engine since the introduction of the ATI's in the 80's, older engines were very good but to this day they are still working on 'issues', it took them over 20 years to sort out the oil burning issues across newer engine models including your beloved mx, engine wiring, cams, injectors and heads are still a problem, a friend of mine owns the largest fleet of dafs in the country, he has 3 new mx engines on standby at any given time, supplied by daf to keep his business of course, he will tell you straight out the daf is not for a small operator! Those engines are fine for light loads or flat roads like you have in Belgium but they don't last over here!

    and fangio........grow up! It's only an engine, if you want to resort to personal insults I will 'rule' then the next time I see you in coblefret I'll slap you round the ears..child! Smiley faces? Really?

    Scaniaman, engine is now past 7y going on 8.
    In fact i will run that truck and engine for another 4y.
    (for those who don't know my engine was rebuilt in 2008 by Paccar free off charge as those early engines 2006-2007 had a design fault in the pistons,they didn't break but used oil,the "upgrade" fixed that problem)
    Doing fine and getting great MPG.
    Oh,and light loads? I think running at 96 000lbs gross can qualify as heavy loads.

    ps those are the EU MX's which run DEF only,EGR was only added in the EU in 2014 which made them the same as North America MX's built after 2012.

    If the PACCAR engines are as bad as this post says then you would think PACCAR engines would have been off the market by now

    The engine itself is awesome. Strong puller, great economy, smooth, and quiet. Its the electronics and after treatment that will put you in the shop 10 days a month.

    Amen! I've spent at least $15,000 on the after treatment. If you buy a Paccar engine now you can get a full 5 year 500,000 mile warranty for about 6K

    I've been offered a truck with a year warranty on a 2012 T700 with 460,000 miles priced for $55,000

    Paccar knows the after treatment troubles and making a slight effort. I think the warranty should be included but still a nice price for a nice truck

    MPG wise, I go from Florida on 95 north. Cruise at 58 and get almost 8 MPG

    We run these engines Paccar engines in Euro 3 & 4 version.
    No emission addons.
    They have been very good.
    Compressors , oil coolers , wiring , alternators , belt tensioners and the odd injector not good but good on fuel and and the hard parts of the engine have been very good.
    We run heavy (+- 110 000lbs ) from sea level to high altitude and they do well.
    If they sorted out all the bolt on pieces I would be very happy.

    I was told by a mechanic that works on Paccar since the beginning. He told me the wiring harness on the first generation of Paccar engines is miss designed and the wires can start rubbing together causing weird codes

    Buy all the warranty you want, if your truck runs three days then goes in a shop for a day.... Runs four days, goes in the shop for a day.... How do you make money? Great, you aren't paying for the repairs and they'll put you in a rental if your truck is down for more than a few days at one time but it won't be, it will be down for a day.
