Whenever I had my XF Dealer serviced it came back with the oil level gauge bang on half way which I believe is correct. It would also bring your attention to any diesel dilution if the level went up.
Exactly same when I got the car serviced at a independent Jag specialist. The bar was in the middle and said OK. I queried the specialist and told him the bar is in the middle and should I be filling it up? He said it was normal for it to show the mid bar and wouldn't recommend topping it up unless otherwise the display suggested.

Don’t forget the bar on the display is the equivalent of the min/max markers on a normal dipstick.

Guys this is what the level is after a drive. When cold the bar is full.

I think you may need approx 250ml of engine oil. I would personally keep it topped up. Especially if you are a regular motorway driver.

Hi KJ
Looking at the pic it seems the bonnet is open? I presume however the engine has been switched off for at least 10 minutes to allow the oil to drain back into the sump? I ask because opening the bonnet and checking the oil is one way to circumnavigate the normal and preferred way of doing things i.e. after a run turn off the engine and with the bonnet closed, wait 10 minutes and then check the oil. The 10 minutes is obligatory or in other words the level indication will not work. Other than that I think I would be inclined to top up as Kennyd90 says and regularly check as per the Jag procedure dictates, bonnet closed, switch off, 10 minutes wait, check oil..
All the best
Brian

Thanks Brian for the suggestion. I will get a litre of oil ordered straight away to make sure it is topped off.
Will continue to monitor and report any other findings :)

Kj, one question I have is, that how long did it take you to take off the undertray of your xf? I will be servicing mine in July and it would be good to get some tips from your experience. Cheers.

Kenny although for the 3.0 here's my guide which will be similar enough....

Hated the number of screws I had to take off for the undertray :( If I recall correctly there were about 10 towards the front and 2 away from the car.

Then you have to remove another shield that hides the oil pan underneath (basically sits or under laps the main tray). I partially removed the shield by undoing 2 screws and 2 nuts and snack the oil tray in the gap. It was enough for the size of my tray.

In total including extracting the oil and making sure every drop was in the oil tray :) 30-40 mins....

Here is a clearer picture of what I mean :) Credit to @Gav
As pointed out by the red arrow that is a massive tray that runs the entire length of the car.

Instead of removing the entire tray I removed the screws as circled in red and it created enough of a gap for my Oil collection tray to fit into the gap.
It was not tight in any way, just a little pull I could see the sump nut.

Personnally I wouldn't bother putting any more oil in. The level sensors are telling you the amount of oil in the engine is perfectly fine.

Why put more in? Do you think the sensors are faulty?

You certainly shouldn't be putting oil in until the max. If the oil gets too hot and expands - it won't have anywhere to go as the pressure rises.

This is how gaskets fail.


Something that was very clearly related to me as a young driver changing my own oil, by my father; a qualified truck mechanic back in the day.
Also backed up by my own learning and training in aviation engineering.

Better to be slightly underfilled than overfilled.


Your oil level is fine.

Thanks Rigger for the suggestion. I have bought an additional 1 litre of Oil, will keep it in the boot when required :) However I do remember the Jag specialist whom serviced it last year said the same about the Oil level. Hence why I am a bit confused. First time doing a oil service on a car with digital oil level display. I am use to the norm of oil dipstick and certainly miss having it on the jag :(

No mate. They are solely a manufacturer.

Hi Kj, that is brilliant! Thanks for this. It'll make my life a whole easier. Appreciate everyone's help here too. Cheers.

Not sure where you got that information from Allan.. but in car engines the oil will have somewhere to go as the temperature rises, you don't 'fill' an engine with oil, you merely put the recommended amount in.. which is not 'filled to the brim'... core plugs can fail due to pressure but that's a different subject...

Stupidest idea ever in my opinion. My wife's BMW has no dipstick. Recently the timing chain tensioner came loose which I noticed due to oil residue on the drive. I had no idea how much oil had been lost and the digital gauge would only give a reading once up to temperature. So, I had to run the engine, potentially low on oil until I had a reading telling me how much to add.

Pete, your right. Most definitely do not fill the engine to the brim. When I said to the max - I meant the max limit on the dip stick.

Pressures can still rise though and seals etc get popped.

Couldn't agree more in regards electronic dipsticks. What amuses me is that they can readily tell you when you need oil but are unable to tell you if you have over filled. I don't think KJ has a problem and his intention to keep the 1 litre top up in the boot is sensible. I'm sure if the oil is checked every now and again there will be no dramas.

Actually that’s not true the car does tell you it’s been overfilled

Thanks Gav, I never knew that but glad I do now. I wonder if that is also the case on my BMW? I could imagine that being a bit more critical given its normal fill is 4 litres and the fill light comes up whereupon it asks for 1 litre. Always bothers me that the car is running on what appears to me to be a very low initial oil fill and then up to 25% less before it needs a top up. Thankfully I've never seen "overfilled" on either car but can remember a few occasions when I've seen others showing slightly overfilled on the dipstick. They were the sort of vintage where it was apparently of little consequence whereas nowadays it appears to be a big no no. Does make me wonder what might happen if you over filled by say 1/2 litre or more not that I am prepared to try it :) . .
