Pete 386 with the Paccar MX engine

Thank you, I'm really not sure how I did got all that in the above post. All I wanted was the bottom line.

 

Very strange that you use those to voice an opinion about the MX engine as Paccar only sold the first MX's in 2006.

And i have an MX engine.
Gross at 96000pounds.
Between 8 and 9mpg.(our version is without EGR)
My engine was rebuild at 220 000km for extreem oilconsumption.
And i was very happy about it as i planned it when i was on holiday and Paccar did the rebuild free off charge.
I now have a younger engine which didn't cost me anything.

About the DEF system,there is one point that nobody has mentioned.
There is bad DEF fluid on the market(make from pellets which they dissolve in water)
People who have used that here have had problems.
So if you buy DEF,make shure it is from a certified source.

 

We have Paccar engines here for many years, they are called DAF here, even pre-mx engines were just the same, Don't you think 220,000 is a bit low to have to rebuild an engine? Even if you have a fresh engine now there is a chance it will last only another 220,000, what then? It'll still have only 440,000 on it, that's nothing! I had one that needed to be rebuilt around the same mileage.I can't understand how you think that's acceptable, we have old Scanias here with 10 times that mileage and they still aren't burning oil! These pacaar engines are a far cry from old CAT or CUMMINS engines, I'll bet you never heard of extreme oil burning at 220,000 in those.

A big difference between your story and mine is that Paccar wouldnt rebuild mine free of charge, as a result of their poor quality engines and shoddy backup nobody are buying DAF here anymore, I for one will never have a Paccar product inside the gates again! Here in Ireland I know many people who bought DAFS which were hailed as a miracle truck at the time , they were thought to be simple and easy to maintain and their simplicity would mean they were reliable, nothing could have been further from the truth, I got sucked into this bs and bought 2 , something I regretted almost immediately !

 

Scaniaman,
you most be right.
Daf has the biggest market share in Europe by selling crap trucks.
It's a wonder that all Daf owners don't go bankrupt.

As i stated before,you are talking about engines from 2003,3years before the MX was on sale.
You have had bad experiences but these have no place in this thread about the MX.

 

It has 500 000km now and still doesn't use oil.

It should also be said that the extreem oil use didn't effect performance.
Would the engine have lasted with the high oil use?
I don't know.(only way to know would have been to run it without rebuilding it and as the rebuild was free,it would have been very stupid off me to experiment)
My guess is it wouldn't have shortened it's life.
I made the intervals longer,took regular oil samples,analyse off those samples didn't show any wear on the components off the engine.
One advantage off burning a lot off oil is that as you refill,the engine keeps getting new and fresh oil.

Having said all this,i still prefer an engine to have normal oil usage.

 

Also I think your claim that daf has the biggest Market share, it doesn't! It's still behind Volvo and scania, then again they are the only decent makes we have this side of the Atlantic , mercedes aren't as tough as they once were, man are crap, iveco are worse, what's left then? Erf? Daf?

 

Any mechanically minded guys here want to explain the reasons for extremely high oil use? Personally I've always thought it was due to engine wear, that's what it was in mine, the rings and liners were completely stuffed! Only other explanation as far as I know is a serious leak. Otherwise the oil is being burnt and that will affect the life of the engine

 

Scaniaman,this part off your statement makes it clear you know not much off the MX.

I didn't say i had extreme oil usage by the time it had 220 000km.
I said it was rebuild then.
If you really knew about the MX then you would have known the the first generation MX either used oil from the first day or didn't use any oil.
The reason why it was only rebuild at 220 000km is because several things were tried before Paccar found the solution.
It was the shape off the pistons that caused the problem.
All the Daf's with that problem in Europe were rebuild at Paccar's expense.

I think that we all would be better served by facts,not by rants about bad feelings.
I know what my truck has cost,how good and bad it was.
Were there things wrong with it ? YES!
Did it get resolved? YES!
Did / do i earn money with that truck? YES!
Do i regret buying it? NOT FOR A MINUTE!
