Hi guys,
My car had its first oil change last week. 2017 R coupe.
The cars booklet states the car takes 6.5 litres of oil which equates to 6.8 quarts. The tech drained the oil replaced the oil filter then poured 6.8 quarts of oil inside the engine. I got back home and checked the oil level. The display says, OVERFILL.
I checked it three separate times and it's the same.
So what went wrong .
How much extra oil triggers the OVERFILL message. Last, how much needs to be removed to resolve this issue. Maybe half a quart?
Thanks guys.

 

You may want to wait for an overnight cool off before checking it cold - mine went from overfill the evening I picked it up from the dealer service to OK the next morning...

 

There is much confusion about how much oil the R takes. Seems that when JLR added AWD to the mix they lowered the sump capacity. If the tech put in the amount for a V8S then it is overfilled. There's an entire thread about it here somewhere.

 

Did you wait the allotted time after driving it home to check? I think you already know not to drive it. I would have dealer pick it up on flat bed back to their shop to resolve.

 

The oil change was done last Saturday afternoon. When i left the dealer, i drove the car like i stole it, very hard. And there was no issue. I parked the car in the garage for the remainder of the day. Then i took it out at night, once again drove the car hard and there was no issue. For some reason, on Sunday i thought to check the oil level just to see that the level was okay. When i checked, it said, OBERFILL. I started to he car, warmed up the engine fully. Shut off the motor, Then checked again approx 15 minutes after shutting the engine, and still says OVERFILL.
He put the proper amount of oil but still reads too much oil in the motor.
I don't understand ....

 

There are only two possibilities: not all of the oil was removed, or too much oil was put in.

 

Agree with Nati.. either not properly removed or too much put in.

I believe the sensor that says overfill is quite sensitive so if you have a quarter or half quart too much and its triggered, its my understanding that it won't really hurt the engine.

My own approach would be to have the dealer remedy the situation and I would witness them taking out the excess to make sure it does not look dirty which would indicate they did not remove all the old oil in the first place. Or, could be a faulty sensor etc. etc...

The oil should be at full with a warm/hot engine and the dealer should check this before you pick it up after the change.. if its still warm I suppose you could check it yourself before driving it home.

A quick question which i should have asked while at the dealer.
how do they remove the old oil because i never saw the car being g lifted up. It stayed on the ground in the bay slot. Do they suck out the oil somehow with a machine ?

 

My dealer sucks it out with a pump, however, he knows what he is doing and has gotten the refill dead on every time on any of the Jaguar cars that I've owned. In my case the master mechanic for the dealer looks after everything on my cars, including oil change and I do hang around to watch/talk with him when I can.

In your situation, they seemed to have caused an overfill situation and as you do not have a dip stick on these engines so you can visually assess the oil cleanliness or level, you should really consider having them remedy the situation from scratch. So, remove some oil and check the condition of it and go from there.
And to add, if I did not have a relationship with the mechanic to rely on, I would be certain to spend some time face to face with the service manager on this.

with a vacuum pump connected to the tube inside the oil filler hole.

 

I may be stating something most know, but for completeness if the car isn't level then overfill can be shown (or possinly unferfill).

When rechecked with the car level it will show oil ok

 

On a related question, when you check your oil and the indicator says it's " ok ", is the warning triangle with the exclamation point in it, lit and visible in the display?

 

Funny you should say that, I checked my oil level a few hours ago, it said "OK", and yes the little yellow/orange triangle with an exclamation mark in it was lit up.

 

I assume the exclamation indicator shows that the ignition is on, but the engine is off. Every car I've ever driven shows something like that.

 

Correct, it's nothing to do with the oil level indicator.

 

I'm a bit late to the party on this, but I recently bought a 2023 F-Type R Coupe with under 6000 mi. on the odometer. One of the first things I did was check the oil level. It shows Overfilled. The car was last serviced by a Jaguar dealer in January 2026. I've left two phone messages for the Service Advisor requesting a call back. Nothing as of yet. I'll give it another try tomorrow. Although I drive the car quite conservatively (most of the time) I am concerned high RPM's might well foam the oil and damage the over full oil pan. I didn't buy this car to have to be concerned about how hard it gets driven but that is where I am now. I have always checked my oil at every fill up, no matter what I am driving. I do not care at all for a system where I can't see exactly how much and the condition of the oil on a dip stick. The instructions state to shut the engine off and wait 10 minutes before accessing the on dash notification. I don't find that a convenience at all and certainly not useful on a road trip. Does anyone know of a after market kit for adding a simple dip stick to the engine?

 

Are you aware that this is a very common problem at these JLR dealerships? Scary but true. In case you don’t know, the AWD version of the car like you have takes less engine oil than the RWD P450. For whatever the reason these ding dongs always seem to manage to put the higher amount of oil called for in the RWD setup into the AWD. It’s a thing.

Are you aware how basic of an operation it is to change your own oil on these cars? It can all be done from the top of the car. That is exactly what Jaguar does. They pump the oil out from the top and then fill with fresh. They do not even lift the car at all to drain from the bottom.

Given how easy it is to do, and given the known repeat issues with oil changes with JLR dealerships, a lot of folks on this forum do their own oil changes. I do. It is very easy.

Something to at least consider.

Cheers

 

As for the last question - after-market kit to add a simple dipstick - has been asked before a couple of times and so far the answer is "no, no such thing".
The usual twist on this question is "can I poke a long rod/cable/whatever down the oil extraction tube to use as a dipstick?" and again the answer is "no, the oil extraction tube has way too many and too sharp bends in it".

 

There are any number of YT videos showing the oil change. About as easy as it gets. A Mityvac, which can also be used for brake fluid, extracts the oil. Record how much came out, put that back in. Important to have the car on level, and check oil level before extraction. Dealer oil changes, outside of warranty, run about $300-400. I buy Liqui-moly, and brand name filters, my changes are about $125. My dealer never screwed up my warranty oil changes, but that is not always the case.

 

You should do that with a dipstick too, and for the same reason. The oil needs to drain back to the sump. There is a way to get the system to give the oil level without waiting. I think it's open hood, open driver's door, but don't remember. I think I tried it once but it wasn't useful enough to me to commit the process to memory.

N.B. When checking, make sure the car is level. If it is filled to upper limit and then checked with the car tilted the right/wrong way, it could show overfilled. Also, it's possible to reset the gauge to the new "average" using a process in the service manual. It's possible that was done and it's now not really calibrated correctly. I've never had reason to try that process but have seen it in the service manual.
