Title: Diesel engine oil capacity
Post by: baroudeur on May 29, 2013, 18:03:37
After my i30 had its first dealer service last May I noticed that the engine oil level was way above the full mark and the invoice shows 5.3 litres which agrees with the Owner's manual.
I have just had the second service done and, again, the oil level is above the full mark.
I tend to be fussy about these things and, although 0.3 litres is unlikely to be detrimental I can't understand how these things slip through the system.
And, of course, I am paying for oil I don't need just like the windscreen fluid that is always full so doesn't need a dealer top up at £3.50.

So, the question is has anyone else noticed this overfilling after a service?

I had a Hyundai Terracan in 2004 and the same thing occurred with that.  That was also was listed at 5.3 litres but was overfilled at the first service.  As I was caravanning in those days I did an intermediate oil and filter change and by adding a little at a time after the  first 4 litres I discovered that exactly 5 litres brought the level to the full mark.  The second dealer  service had the same result and I complained about it.  Subsequent services on that car and my second Terracan were fine with the level at the full mark and I believe there was a bulletin advising dealers of this.

Any comments?.

I've only changed oil on mine once and 5 L equals the full mark. I think that's the common experience.

Like you say, full capacity of the CRDi is supposed to be 5.3 but mine never took more than 5ltrs at any service.

I supplied 6 at the first service but got a full litre back.

It appears that the residual oil left when drained must equate to about .3Ltrs

I have changed the oil several times in my 2007 CRDi.  The most I have ever put in would be 5 litres. 

I have never found it easy to check the oil level.  In other, non-diesel cars, I have checked oil levels with the engine cold and the oil level was very clear on the dipstick.  The oil level seems to be less clear/precise on the CRDi's dipstick.

When draining the oil, I don't think I get as much as I had put in, so I guess it uses a bit (not enough to be a concern).

The extra 300 ml doesn't do any harm, don't lose any sleep over it. :wink:

5.3l here as that's what hy state & guy I went to always put 5.3. have to also remember the oil filter is upside down. so some oil will run out of it when left standing best to check when warm and short time after you turn off motor. they all state don't over fill as could damage motor but that's just what they all state. a small amout over don't hurt. I saw a guy in USA when I was there miss understand measurement & filled a V8 diesel motor completely up think was close to 20L? and started it bang

That's right, oil, like other liquids is incompressible, so if you fill up the space where the crank rotates, you're going to blow the sump right off. Most likely, when built from  new there is no residual oil present in the motor, so 5.3 is required. In use at oil change, there will be some oil on any horizontal surfaces and valleys which doesn't drain away, so 5 L is most likely enough. 300 ml  distributed over the sump area probably amounts to a few mm rise in sump level.

As stated, capacity 5.3.
My mechanic has only ever put in 5.0 to the full mark.

Post by: agentr31 on May 30, 2013, 12:03:15
in my 1.6 diesel i put 5.5L and it takes it to just over, like 1mm...

as stated above the oil filter housing holds a fair bit, and it has to fill after you start it...


just remember, rather too much, than too little!

only service I got 5-3 ltrs of oil in and didn't go over the fuel mark,was when I let the sump drain overnight,I cleaned every skeric of oil out of the filter canister,every other time have only used 5 ltrs which has taken it to the full mark.

I think we have discussed this issue before, and came to the conclusion that the 5,3 L was dry fill, and 5,0 was when changing the oil.

When I change on mine, I put in 5,0 liter, start the engine until oil pressure lamp turns off, and then wait at least 5 minutes before checking the oil level Again.

5,0 liters allways reach the top mark of the oilstick.  :goodjob2:

Only service the dealer has used just 5 litres was the 15,000k service. Every other service they have used some from the extra litre bottle I supply.  :undecided:

Perhaps they are topping up their own cars?  :lol:

I agree that the 5.3 litre is a dry engine fill so a filter and oil change only requires 5 litres.  On the dipstick 5.3 litres is about 10mm above the full mark.

What really annoyed me is that I stuck a  note on the rocker cover asking that only 5 litres of oil be used.  Yesterday, whilst I was out, a message was left  by the dealer asking if my service experience  had met my expectations.   I will respond on Monday.

Excess oil at £3.00  and windscreen wash that they didn't put in at £3.60............................... :confused:

You need to ask why you have been charged for a service you did not receive when you respond next week.

I would hazard a guess that they reply by saying that it is a mistake as the technician ticked a box but shouldn't have.

So you reply -specsavers

I specifically requested that I didn't want windscreen wash added at my last service. I got sick of paying for it knowing it wasn't required as I fill the bottle with my own.
At least they listened.....

In spite of me telling them the air filter didn't need replacing as I run a K&N filter, it's listed as being replaced......
No charge listed for the filter so I'm assuming it actually wasn't.  :lol:
Just annoying that they can note on the invoice that I supplied all filters but they can't remove the "replaced filter element" from the list.....

And the environmental charge of $5.00 and workshop supplies fee of $2.50 shits me....Next they'll be charging me for the paper the invoice is printed on...  :lol:

I am on my fourth Hyundai since 2003 and right from the first car  I raised the question of why windscreen fluid was charged when the container was full to the brim.

Answer   -   it comes in a service pack  (like oil in 5.3 litre packs?)!!!!  Load of rubbish of course just the first  answer that comes to mind.  They think we are easily fooled.  I then asked "next time my car is serviced may I have the washer fluid pack you will not have used?"

This morning, after a run out, I drained off 350ml of engine oil through the dipstick hole with a suction gun.  Level is now on "full" mark.  What worries me is that the oil seems VERY black after 70 miles so I now wonder if it WAS changed?  :evil:

New oil in my CRDi goes black very, very quickly.  I don't know why, but it does.
Title: Re: Diesel engine oil capacity
Post by: Phil №❶ on June 05, 2013, 23:57:29
It's because Diesel engines swallow some of their own exhaust gas, to reduce nitrous oxide emissions, this gas contains soot. Controlled by the EGR valve, a source of much discussion and debate as to whether to disconnect, or not. :confused:
Title: Re: Diesel engine oil capacity
Post by: rustynutz on June 06, 2013, 00:51:23
And also the last bit of old oil that's left in the sump discolours it.....
Title: Re: Diesel engine oil capacity
Post by: Eureka on June 06, 2013, 07:38:07
I am sure the remnants of the old oil have something to do with it but I'm guessing it might be more to do with what Phil says.  My previous vehicle was an XF ute.  I changed the oil in it many times and the new oil didn't discolour anything like the CRDi does.

That may have had something to do with the sump plug location on the Foul Can too....  :undecided:

because its diesel...

notice how sooty the exhaust pipe is? well that goes past the rings into the oil a bit too...

I realise that as   I have had diesels since 1983.

Perhaps I should have qualified it and stated it is exceptionally black compared with previous oil changes.

I check the colour of the oil in my car the day before the service and although it was a lighter shade of black, if you can have such a colour, the oil i had in the diesel at the same mileage/12 months was a blacker shade of black.

Just back from holiday in France/Germany.  1200+ miles, half fast motorway and rest  touring local attractions, gave a brim to brim of 51.75 mpg and the car computer gave 52.0 mpg.......satisfied.

Back to oil I have had a reply from Hy U.K.

Thank you for taking the time to contact Hyundai Customer Services.
With regards to your enquiry, the level could rise above the max mark when stood for a couple of reasons, such as the oil retention in rocker area / breather system.
With some vehicles if the oil filter cap is not removed prior to changing the oil, a quantity of oil will still stay within the housing therefore having an effect on the level


I have replied asking them to explain why, if 5.3 litres is the correct fill, it takes the level above the full mark as the servicing is done by a Hyundai dealer presumably to the correct standard and therefore the explanation given does not address the problem.

They have replied

I have taken the liberty of forwarding your comments on to the relevant department.

Perhaps this should have been done on receipt of the first enquiry?

I'm still waiting for a reply since last August

Well another year gone by and another annual service. Hyundai never replied to the question last year after referring it to 'a relevant department'.  Perhaps there isn't one so I will never find out.

This time the oil level is exactly on the full mark  :goodjob2: ...and the invoice shows 5.3 litres.    :confused:



I think the air con (Comfort model) may be playing up as it doesn't seem to get as cold as I recall from last summer and the dismal temperatures up until now haven't needed a cool setting but I am off to south of France in a couple of weeks.  Has anyone ever taken a temperature reading at the dash vents with the settings at fully cold and fan on 2?  I get a reading of  4°C which rises to 6.8 with  fan at 4  max but my wife's new  i20 gets  down 1.8°C on fan 2 and goes up to 4°C at fan 4 then drops back to 2° very quickly.

I supply 5 litres for each service, despite the 5.3 capacity and it always seems to be enough.
I started off supplying 6 litres, but the 1 litre bottle always came back unopened, so I now just supply a 5 litre container.

Yes last few services I have done or had done only supplied 5 litres,it has always come up to the top marl on the dipstick,I once did a service,let the oil drain overnight,cleaned the oil filter cup out(as this always has at least 100 to 150 mils in it)I then measured out exactly 5.3 litres and just threw it in the motor,Low and Behold,it was over full even after starting the motor to check for leaks,then letting it still for a couple of hours before rechecking.

I supplied 5lt last service, they noted on the invoice that only 5 was supplied, yet to this day, the oil is at full mark.

For Lila, I will be removing the oil etc using an electric pump for the 1st time.

BTW If you want to get ALL the oil out with a pump, I find the plastic white party balloon sticks work well with cool oil, not hot obviously. They fit down the dipstick, but remain stiff enough to get to the very bottom of the sump.

Just looking at this old thread, my first i30 CRDi i always got same guy to service, he always took his time draining the oil, would take filer cap off. put it up on car lift, remove sump plug leave it to drain, then after put sump plug back lower it do oil filter & if needed fuel filter. then take his time putting the oil in not just tipping 5L in & saying thats it , he would add a bit check dip stick ardmore check dip stick, start motor till oil pressure light goes out as that indicates oil filter full ( but oil will start to run out of that as soon as you shut off ) he would double check oil level & always put the 5.3L in. i once only gave him 5L but he said when checking it needs more. .3 is not far off half a L.
then i get my second CRDi i30 & for one reason or another it got service by a dealer. first dealer service i supply 5.3L in containers & ask for container back. i get home check oil it's black, when my old mechanic did the service oil was dirty looking too but not this thick black like b4 service. so i check the containers they had only used 3L gave me the rest back. then next service back to old mechanic told him i suspect the dealer pump oil out but don't always pump it all out. he shakes his head as the older diesel oil gets the thicker it gets . he puts 5.3L in. then i move so go to a bush dealer was cheaper than service in Sydney. they use 5L pump it out as they told me after i asked. so if they pump out you got to expect dirty oil still in there. also the EGR valve has got to add some soot eventually to the oil.
i just change to a little Hilux truck diesel ( not new ) ask toyota dealer i got it from to do full service as part of deal, these baby's hold 6.3L of oil , i check the dip stick this motor has done more k's than my i30 CRDi but oil looks clean like a petrol motor so say to tell oil has just been changed, i drive 300K check oil level oil still looks clean not perfectly clean like out the bottle still not the black i'm used to seeing. might have had EGR valve blocked but who know's. i don't think blocking EGR valve does anything for performance. but could possibly cut down soot in oil.
my advice ( if you want it as i'm not using it LOL ) is find a mechanic that drains oil *& takes more care with checking level it's hard as oil runs out filter into sump after standing, so makes level look higher. then you re start you will see the oil pressure light is on for a short time every time you re start when it's off the oil filter is full so always check oil soon after motor has been runing not after its been standing for hours.
