So, I did a little testing for the Oil level check indicator and the results have completely confused me.
6:00 pm - I Check the oil level. The car has not driven for over a week now. This is what the oil level indicator shows me.
6:20 pm I drive it very gently for around 15 mins in traffic, Engine reaches half warm on temperature gauge. I traveled around 2 miles in total. Sat around 10 mins in the car and checked. Oil level actually went down.
9pm: I come out of the Gym. Get into the car, check for oil level again. It showed me the same dropped level as 6:20pm
9:45pm I drove the car a lot more now and I pushed it a little harder than before. Drove in manual mode with revs between 3k to 4k. Did a few quick 5mph to 20mph. Come home, parked. Came down after 15mins and checked the oil level again.
I mean what on earth is going on here. Am I crazy or doing something incorrectly. Oil was always measured on a FLAT surface and in the same spots. Outside temps were avg around 45F/8C. I am freaking out over this.
Just a thought, I don’t have a a car without a dipstick so please take this however you wish to.
As the procedure to withdraw the oil when doing an oil change is to use the small tube in the oil filler cap would it be possible to use a long thin probe to check the oil level?

If I remember correctly, somebody did try that but discovered there were a few sharp bends in the tube which made it impossible.
Keep in mind, that the level between to two lines represents a single qt.(or possibly liter). The variations represent mere ounces. Nothing to fret over.

Thank you Unhingd. What should be a warning flag? I know it indicated a level almost near to the bottom line once. I just want to know some indication as to when I should add more oil or take it to the dealer. Clearly if I would have added more oil when it showed me half or near the bottom level indicator, it would have given me an overfill warning as soon as I started driving it.

I look at the oil level as specified: 10 minutes after it is warmed up. If it is at 3/4 (very infrequently), I add a cup of oil. As with any testing, consistent methodology is the key (a whole organization dedicated to this subject: ASTM)
Mine just below half. With other cars I’ve always added a bit to keep near the max on the dispstick. The engineer in me wants to add a bit to bring the level up but the owner manual says ONLY to add when the display says “add oil” - quite a dilemma.
Whats the consensus. Add a drop to raise the level a bit or wait .?

If you add a quart, you'd overfill it. I personally would add less than a half qt. If you let it get to the add oil stage, you'll have no clue how low it got.
Excited to join this illustrious thread. I have had two oil changes at my dealer so far without incident. Third time was a charm. Look how much I had to extract in order to get the yellow bar in the middle of the guardrails.

So The F gets its annual today. I look at the invoice and sure enough 8 L of oil. Check the oil level. Overfilled. It never ceases to amaze me how the dealership service departments can continue to make such well known errors.
I will email them (so I have a record) and call them in the morning. (Its 6:30 PM). Always something.
I just had a service (where I found out about my other troubles...) and the service person said they just fill it from a big vat, into which they program in the vehicle type. So if this is happening, maybe the programming is wrong? (And lots of cars getting overfilled.) Mine was OK this time, I checked before I left the lot.
Pretty sure the AJ133 and AJ126 engines already do this.
Download the AJ133 Technical Training document from my Dropbox here: https://www.dropbox.com/s/8y4iax9hm2...%20V8.pdf?dl=0
and check out pages 69 and 70.
From my reading the reason JLR say you should warm the engine up and then wait ten minutes before checking the electronic oil level indicator is so that almost all the oil has drained back into the sump, and not because the oil needs to be at any particular temperature.
I have checked the oil level indicator under a range of conditions - left overnight stone cold engine, hot engine, warm engine, follow 10 minute wait procedure and so on, and I get the same reading every time - "Oil level OK" and smack on the Max mark.
Nice document, is there a similiar one for the V6 that you can share?
Incline, even a slight one, makes a huge difference.
In a picture GGG just posted, over 2 liters down.
This is also thanks to Cambo's app that shows numerated oil levels.
