DAF oil

I recall some time in the past someone mentioning that DAF;'s don't like
modern oils and that a simple monograde was better. Anyone found a brew that
they like? We are having problems with smoke after a period of slow rev
running eg tunnels and it has been suggested that using 15-40 could be the
problem. Have tried emailing Chris Ries with no joy- change of email
address?

Use only straight SAE 30.  It will take a few thorough oil changes to get
the 15 etc out before you really see the difference.  You can also try
'ambesta glaze buster' which is an additive to the diesel and seems to solve
some smoke problems but even with this you should still switch to 30. The
commercials use this so any chandlery should stock it, Total, BP etc all
make it. I've also used straight SAE40 which worked well in my DAF 475 but
is really for summer temperatures only.    

Could possibly be worn valve stems or worn cylinders/rings but try changing
the oil first, much cheaper.

Chris is the smoke king though.

You can also find monograde oil at most agricultural coops in France.

Greetings,
        Chris Ries is at his barge at the moment and without email
connection.  He will be returning to the e-world late this week.  I am sure
he will have an input.
        I have a very old DAF 615 that I have put 1600 hrs on with modern
15w40 multi-grade oil and have had no problems what so ever with smoke.  I
am quite sure mine is not the only one running on 15w40 and not smoking.
        What explains some smoking and some not?

Cheers, Roger

Folks,
I have absolutely no experience with this motor. I do, however, have  
45 years of experience racing sports cars and I'm sponsored in part by  
an oil manufacturer, so I'm not exactly a neophyte either.
That said, I'm not aware of any technical reason a multigrade oil  
would not work just as well as a single grade oil. The viscosity of  
oil and and how this is measured  is defined in the specification that  
the manufacturers follow in labeling their oils. In the USA this is  
generally both a mil-spec and an ASTM spec. I assume that the ASTM  
spec is what is used worldwide. Anyway, the requirements for the  
viscosity of an oil is actually specified as a range of viscosities  
vs. temperature. To be labeled, for example 30wt, it has to perform  
within the ASTM spec at all temperatures. Thus it's viscosity in  
actually much more at cold temps than at warm temps, but we all seem  
to know that we are mostly interested in the hot viscosity, which in  
this case meets the requirements of 30wt. A 10w-30 has the same  
viscosity at elevated/running temps, but has a much lower viscosity at  
cold temps, in this case acting like a 10  wt oil.
So a 10w-30 and a straight 30 wt oil will have the same measured  
viscosity at elevated/running temp. I can't imagine that the DAF only  
smokes at low temps, so I don't see the reason either wouldn't work  
equally well.
But then again I'm sometimes too technical for my own good.

DAFs notoriously do smoke most at low temperatures, when starting up
especially, and when under light load. I assume it is due to the rings not
expanding to scrape off all the cylinder oil but could be other things maybe
even the valve guides.  There is also just old age and wear.  Switching to
SAE 40 then 30 has stopped this in my DAF 475, plus the glazebuster helped.
A side benefit is it has reduced the annoying drip down the thread of the
cambox cover's retaining studs.  

If your engine runs fine on multigrade and you are happy with that then
leave it that way. You are probably reducing initial wear and if there is no
smoke you're not likely to build up excessive carbon in the cylinders.   If
it smokes more than you like either try a monograde (which is the original
spec), a glaze buster fuel additive, a valve overhaul, a new short engine or
a replacement engine.  In order of cost.

David

If that's 1600 hours from new it's a spring chicken!  That's about the same
as 50,000 car miles, not a lot for a big 6 cylinder diesel engine.  Save the
monograde for its retirement and old age.  My DAF won't reveal its age but I
think it had a hard misspent youth in a lorry.  

NB this subject has coincidentally also cropped up on the main list,
competing there with 'dry dock in Burgundy'.  I've suggested they swap
lists.

Your explanation certainly matches my understanding of oil viscosity and why
single grade or multi-grade is not the primary issue in smoking DAFs.

I should have mentioned that this is a 615 engine and has done only 250 hrs
since installation. It was very expensive  and sold to us as a total rebuild
though reepeated requests for a list of work done to it have so far been
ignored; however that is another story. We have been travelling south fron
Friesland since July so glazing is a possibility. Oil presssure kept
flicking upand down between 2 & 3 bar but has now settled at about 3 bAR.

The recommended oil for that engine is monograde:
SAE 20 at ambient <0C,
SAE 30 at ambient -5 to 30C,
SAE 40 at ambient >25C

Oil pressure sounds OK should be 0.35 (worn) to 1 bar at idle and 3.5 - 4.2
at 2000rpm, do you have the manuals? If not email me off list and I will
email them (they are quite large). Max oil pressure is adjustable on the 475
and 575 at least, I assume the 615 has it too.  

Is the smoke black (diesel), light blue (oil) or white (steam)?

Is the smoke black (diesel), light blue (oil) or white (steam)?


Careful, white smoke is not necessarily steam, it is more likely to be
incomplete combustion i.e. unburnt diesel. It is difficult to tell which,
coolant (i.e. antifreeze) or incomplete combustion (i.e. unburnt diesel), or
a mixture of both in certain circumstances. The best way is to smell the
smoke and deduce from the characteristic odour of either.

Yes quite right.  Simplest test however is that steam will largely disappear
after emission unless it's a very cold day, unlike smoke which will blow
away.

Smoke is blue though oil level not dropping to any discernable extent. It
used to look blue or white depending on light until we renewed all the
injectors.Now just blue. If we are running at say 1400+ revs then smoke is
not too bad. If we wait for a lock for say 15 mins then we leave blue smoke
screen for 15 mins.
Yes oil pressure adjustable and we were advised by supplier to drop pressure
below what it says in manual (which we have.)  This made no difference.
I'm waiting for a new stock of filters and will try swappping to monograde
when they arrive. Our engine room gets bl***y hot so perhaps 40 grade
best(?) Ian.
