This is the first car I've had with an extraction tube in the filler neck. When needing to add oil can or should you put the filling spout (funnel) over the extraction tube or is it better or is it required to avoid refilling over the extraction tube. My plastic funnel is small enough to slide along side the extraction tube. Also, would it be normal for oil to read "ok" if checked cold and then read under filled (by 1 liter) when checked after warm up? I'm checking the bonnet up/driver door open method. Thanks.

 

Doesn't matter. They both drain to the same place.

If you are not letting the car sit for a while after warm up all the oil may not have drained back into the pan. Might explain low warm reading. A full quart is a lot though.

 

Good thought I the low oil. I'll check again with a good ten minute wait.

 

 

+1 on that

 

Well, I decided to recheck my oil readings before adding more oil, so I drove the car for 20 minutes or so at pretty good speeds (About 8 miles). Parked in the parking garage at work on level space and waited over ten minutes. I checked using the manual procedure (not the open door/open bonnet procedure). The read out was initially "ok" with the bar reading just above the bottom of the vertical bar, it then flashed over to read "Add 1.0 L". then flashed back to ok then back to "add 1.0 L". It may have done this three times or more. I tool a picture of each status, but can't get the pictures to upload.

I suppose the car is on the threshold of needing the 1 Liter but can't make up it's mind?

 

That would certainly be consistent with showing at the bottom of the vertical line.

 

Add 0.5L initially to see if that's sufficient to take it into the "OK" zone.
Not sure what the resolution of the sensor is, but it appears to be pretty coarse.

 

That's what I'm thinking as I certainly don't want an overfill situation.

 

Vince, don't forget that the normal dipstick display is some unspecified average. If you add oil, you should use the instantaneous display mode, and separately, resetting the average would be a good idea, as we have no idea how long it takes the average to catch up with the new level.

 

Dave, When you mean instantaneous, are you referring to the open bonnet technician check method? If so, can you add the oil when the car is cold (after sitting overnight) and then do instantaneous check or should the car be driven for some time (say 8-10 miles) then allowed to rest for the ten minutes, then checked?

Also, how does anyone know that they haven't overfilled the car if it is reading an unspecified average. If it says to "add one liter" (if it is a steady reading and not switching back and forth to "ok") how coarse could the average be that wouldn't make an overfill happen? I'll stick with a half a liter and then wait for an oil change in the next month or two when it's due for service on it's in service date.

Dipstick anyone?

 

"Dipstick anyone?"
A resounding yes, but Jaguar apparently decided we don't need no stinkin' dipstick--at least not in MY 2018.

 

 

How do you "clear the average?"
Thanks.

DJS, Make sure you do the hokey pokey and turn yourself around.....:

 

 

I have a 14 base. I read people talking about various ways to check the oil level. I only know of one via the menu. What is this instant result you are speaking of?

 

See post #15, above...

 

Some questions, DJS:

1. What is the "instantaneous mode?" Checking the oil level after a 10-minute or so shutdown?

2. What is the "open bonnet technician check method?" Is that method the same as the "open door/open bonnet procedure?"

3. I get the process of clearing a previous value in general, but what am I looking for on the display? Where does the "average value" show up and how do I know if it (the average value) has cleared? (After following Step #15, I found no difference in my oil level display from a check taken just prior to applying Step #15.)

4. I read 1/3 below the top fill line/bar. How much oil would you say I've used? (1,500 miles on this oil change.)

I have a '17 SVR 5.0L if that makes any difference on the process of checking the oil level relative to the 3.0 L motor. Not assuming anything here.

TIA, DJS. Much appreciated. I'm feeling a little chagrin at having to ask these questions since an oil level check should be so simple. (I agree with fujicoupe. "Dipstick anyone?" My first rant in 2019, heh.)
