Question oil level too high after servicing

hi,
maybe it has already been adressed but i don't find the answer:
we are at least 2 locally talking together with same issue with 3 different mechanics doing the same thing: oil and filter change for 2 cars over the last 2 years:
after the service is done at subaru dealer, arriving home we let the oil rest from 5mn to one night (not much difference) and check the level: it is every time consistently around 1cm above the maxi on the dipstick arriving no far of the twisted part of the dipstick. my particular car came with the same too high level new from factory.
any logic in this?
did you notice the same thing?
this happened with 3 different subaru dealers so I guess there is a reason for that.
thank you for the info you can give me.

(garage floor is really flat, new with tiles no bumps nothing: i can move a car in every direction by pushing it with one hand with no significant difference of strength needed)

I wonder if the problem is your dipstick? I do my own oil service and filter, complete drain and 5.5litres of oil added, after a brief run to check for leaks etc, the level is correct on the stick.

dealer charged 6.0l for a 5.9 needed not sure if he rounded to nearest integer or really put 6.0l.
as I said it arrived to another person I know measured in a different garage than mine.
mine is perfectly horizontal, checked with spirit level last year when making it
edit: i believe there has been change in design altering the engine oil capacity could be that ...

ok good to know thank you...now what is the technical base for saying this?
Here in europe when the high pressure direct injection diesel started in all diesels (mid 90s') all the concessions of most (if not all) brands received a note saying that it was critical not to go over the max mark because of engine destruction due to lubricant going back in engine on an uncontrolable way and being the combustible even with contact turned off...we could the first years see some cars on side of the road with an unstoppable engine going wild in revs until it dies because of non respect of these specifications so we may be a bit oversensitive on that respect compare to people who don't have diesels in their country.
it does not worry me more than than on my 2.0i forester (that was on correct level by the way), but, on my 2.0D i must say that i'm wondering what is the reason justifing this behaviour and where does the risk of having problems start in term on oil level on the dipstick.

Remember oil dipsticks are indicative only, they are not a calibrated instrument! The oil capacity with filter is 5.5l (5.9l if euro 6), if this was added at service, then what is showing on stick is correct.

yes it has as far as i know a friend has had is 2.0D almost a liter overfilled and this is the excuse Subaru gave him there are 2 diferent capacity in function of fabrication date before 2014 and after (if i remember correctly the date) practicaly: 6.5l for old 2.0D and 5.5 for recent 2.0D and 5.9l on our user guide... and as here in this zone of france subaru is near zero in sales volume the dealers don't see recent cars so often and they do 3 to 4 of this litles selling brands to make a living...so they not so specialized...hence my question here i might get more sensibles answers :)

here is the excess oil in a turbo diesle :( :

Perhaps early '14 still has earlier design ee20, filling with 5.9l would definitely bring it over capacity. What is your full engine designation?

Ee20zvuxlb (this code would score well atcomputer password safety analyser :)) )

edit euro 6: 5.9l of oil according to the F.M that I Read ;) (just did a double check to look less stupid just in case.)

Personally I fill using the dipstick as I've no idea how much remains after draining.

But I *do* leave it a bit low on refill, only topping up after drivng a couple of miles and waiting 5min for drainback. No mechanical is going to do that, even if it *is* in the manual...

ok I have the answer from the mechanics..pretty simple in fact:
he receives the oil in cans of 2l so 5.9l=3 cans, he did put everything so 6l...he agreed it was too much and pump out the excess...
they probably all square up this way instead of leaving the can in the truk for the driver to top up if necessary.

not very serious in my opinion...as for the risk with the oil excess...when it starts to be dangerous...no idea :(

so if "no idea" is the answer i'd say let's respect strictly the manufacturer specifications to NOT overfill. at leas for this dealer... if you don't know don't take risks...no?

Thank goodness it was only 100ml over, I'd say no harm done but still good that you are getting it pumped out.

he actually pumped out more like 0.3-0.5l to end up with a level just below the max point.

after reflexion could it be that instead of relying to gravity to drain the oil he pumped it out through filling hole leaving some oil in the engine?

edit:200km and the oil is already dark

this would make sense...if the dealer did not charge for the drain plug gasket

you can't use an extractor on the later EE20s, the dipstick tube is a really odd shape and a suction probe won't get into the sump. I've tried...

well after having another overfill by 400ml in september I had the same problem again after yesterdays service... I had to go back to the workshop to have 400ml extracted... again
And when I left the car the day before I reminded them that last time they overfilled and that I would check their work...
This drives me mad... no other subaru dealer in 80 miles radius :( and 2 years of waranty left...

mind you in france I know of 2 subaru dealers that do exactly the same crap... that is puzzling me :(
