So I tracked my car yesterday, while it was cooling down I decided to check the oil, it said oil overfill. Now the car got very hot obviously and oil expands, once I was home and the car cooled down i checked the oil and it said OK. Is the car filled properly as to when you track it states its overfilled? Does jag account for that?

 

I believe the thin modern oil expands a lot when hot, and Jaguar have designed for that. It's why they insist you don't check levels immediately after turning off the engine.

 

The engine oil level sensor has the capability to measure oil temperature, so in theory it could compensate level for temperature

Oil level indicated is dependent on the car being level.

It can indicate over level when on a slope but show level ok when car is parked on level ground.

You can get an oil level after running the engine, there is a delay time of approximately eight to ten minutes after the engine is stopped.

Or raise the bonnet (hood), select oil level then press cruise control cancel button twice to toggle to immediate reading.

With the latter method you can observe the indicated level increase as oil drains back to the sump.

 

that's interesting, didn't know you could force read oil levels.

 

Here's the procedure to get an instant reading during/after an oil change...

Dave, what do you make of the steps right after that for "updating average oil level?" What is that for?

 

Hi Justin,
I assume the car averages readings over a number of starts, so this would reset the average. In my case, the oil is always at ‘full’ before changing, so it wouldn’t make a noticeable difference if I did that.

 

so does no one know why my car showed oil overfill at the track, would the car account for oil expanding? Trying to figure out if I'm in trouble here.

 

If the oil level is showing full and ok when cold, it will show overfilled when coming off the track. No concern here. If you don’t want this to happen, fill oil to the half or 3/4 mark when cold.

 

So I just bought a 2018 F type R on the 22nd of this month. It was a leftover demo with about 1000 miles. Got a new car title. I’ve put about 500 miles on it since I bought it. I’m still learning all the settings. Tonight I was sitting in the garage going thru some of the screens and settings and came across the oil level check. It said overfilled, or over full whatever the message is. The car had been sitting in my garage, level, and hadn’t been run or started today at all.
Do I need to do anything about it? I can call dealer on Monday but seems odd. Thoughts?

 

Being a 2018 it will be AWD and it's quite common for JLR dealerships to overfill them with engine oil, as the AWD sump capacity is around 1/2 a litre less than the RWD sump capacity. A lot of dealerships either don't seem to understand this or just not care, lots of threads and posts around here about this.
So yes it is probably overfilled a bit, but many AWD owners here have had that experience and it has never caused a serious problem for any of them.
You have a couple of choices:
1. Contact the dealer, complain, and insist they fix it. Some will send a technician around to your place to drain the extra oil, some won't, some will say "bring it in and we will fix it". Depending on how far away your dealership is this won't be a problem for the car but it will probably be inconvenient for you. Don't bother getting it flat bedded to the dealership as this is a minor problem not worth that expense or mucking about.
2. Get yourself a vacuum / extraction pump and remove the excess oil yourself, Mityvac is a popular brand.
This is how dealerships do an oil change anyway, there is an oil extraction tube smack in the middle of the oil fill hole.

 

Once again thank you OzXFR!

 

Follow up question to my earlier post. So after seeing the overfilled message on my new/leftover 2018 I took it to the dealer on Saturday morning. It turns out the dealer doesn’t have service hours on Saturday. SMH. So I removed the excess oil myself with a vacuum pump and texted the sales rep at the selling dealership to ask if the oil was changed. I was curious about the overfill. He said it was changed the day I took delivery.
Here’s my concern. The oil I removed was black. If the dealer wouldn’t have told me it was changed less than 500 miles previously I would have thought it was never changed. Keep in mind the car had 1040 miles on it when I took delivery, and about 400 miles on the supposedly fresh oil??
Any thoughts on why the oil would be black?
I would expect it to be kind of a honey color.

 

Send a sample off to Blackstone Labs. They’ll be able to tell you why it’s black and whether it needs to be changed. $35 for a thorough analysis including TBN. (Additive level)

 

@Unhingd has the best advice.

Many folks on BobIsTheOilGuy.com prefer Oil Analyzers over Blackstone these days for direct injection engines because they actually measure oil dilution from gasoline, not just infer it.

That said, modern detergent oils should carry impurities in suspension (including particulates from cold running) so they will darken up within only a few hundred miles. I'm guessing your oil will test fine.

 

Hope so. I guess I’m a bit old school. Back when cars actually had dipsticks when you went to buy a car you’d pull out the dipstick. If the oil was dark/dirty looking you would infer that the oil was in need of changing, at best, or that the car perhaps wasn’t well maintained. And also give it the smell test to see if their was any type of burnt smell. I’m showing my age. I realize things have changed. I was also told to change oil every 3000 miles, which I rarely did. Now it’s 15000 or more.

 

RWD takes 7.25 L, AWD takes 6.5. A large amount of dealers fill 7.25 for both. I believe this is because the service manual was not updated. The tech inserts F-TYPE V8 and the machine pumps in 7.25 L is how I imagine it happens.

I complained when it happened to me and they sent a service rep and a tech to my house to take care of it.
