As many of have had the dealer overfill the engine oil.


Here is the result.

Yikes. Just the weekend, I had to remove 750ml of oil from my new-to-me 2017 R. I have no idea why the dealers overfill the AWDs. And for the love-of-God, please put dipsticks back in these engines? By all accounts, the electronic oil readers have been an unmitigated disaster.

 

One excuse is that the RWDs require more oil, so dealers appear to sometimes use that measure regardless of drivetrain.

 

I watched that teardown video when it was posted here last week. There is nothing conclusive to prove the failure was due to overfilling. He says so in the video. One thing that is conclusive is that the car was totaled due to body damage, but the engine was a complete write-off. He notes that this seems very much like a case of insurance fraud, and I have to agree. Nine quarts instead of 5.7 isn't just a case of using the wrong spec on filling. There's something else going on. I can think of a possibility or two, but that's as much speculation as failure due to overfilling.

 

And, the early documentation was only for RWD's (before AWD was introduced). Maybe Jiffy Lube could claim confusion, but not a JLR dealer.

 

And to be clear, my 2017 R was sold by a full-on JLR dealer, with a sheet showing service done at the time of sale. This includes a full oil/filter change. And I still had to remove 750ml to bring it back to spec.

 

My dealer overfilled the oil not once, but twice ! And the second time I had specifically mentioned to the service advisor to tell the technician who was performing the service not to overfill it !
I got the overfilled warning when I checked the oil level on the menu and used my Mityvac to extract about 7.25 liters (a little more that 7.6 quarts). The stated capacity of the V8 with AWD is 6.5 liters / 6.9 quarts or 6 quarts, 29 oz. I carefully pumped 6.5 quarts back into the car allowing for some oil that would remain in the filter and engine galleys.

So it was overfilled but not grossly so. But still more that it should have been. Another negative side effect of the overfill was that the electronic oil level gauge continued to show overfilled for a long time although it would show overfilled and then a second or two later it dropped to just below the max reading. I believe that had something to do with the fact that the gauge is showing an average reading. I tried switching it to the "real time" reading but that didn't make a difference. After I put about 500 miles on the car, the gauge seemed to reset itself and now reads accurately.

It will be interesting to see what the cause of failure is, provided he can determine it anyway, in the engine being torn down. It would take a real pinhead to put 9 quarts in that engine. I would think someone just dumping a 5 quart jug into one would be a more common mistake because that's what so many cars take these days.

 

The inability to get a real-time reading of oil level is maddening. I also tried the procedure in the service manual (hit the cruise-control "can" button twice within 2 seconds while in the oil-reading screen. Didn't do anything.)

As the sensor is giving your an average, you're just guessing when it comes to add extra or removing too much. I don't suppose a dipstick would fit in the fill tub insdie the oil cap? Anyone tried this?

 

The hood also has to be open. Works for me.

 

This. It will work with ignition on (doesn't have to be running) and the hood open.

 

Ah! Thank you! I'll give it a try. Awesome, thanks for posting.

 

No way for the dip stick to go down the oil suction tube. Too much bending of the tube as it snakes around before going to the bottom of the oil pan.

I though someone posted the problem comes from the fact that Jaguar and many others have automated oil filling stations to save time while servicing the cars? You punch in the car model and then it dispenses the correct amount of oil. But the list of capacities had some errors with the big one being the AWD and RWD take different amounts of oil.
Leading to over filling the AWD models. Apparently the dealers don't check the oil level after filling because the automated system is supposed to eliminate all that?

He couldn't.

He notes that the whole thing is suspicious (totaled due to rear end damage) so perhaps someone added enough oil to get it running enough to stage an accident. Again, just speculating, but that's all we can do here.

 

One problem I am having with my newly acquired V8-S is finding a good source for all the exact and accurate fluid capacities in my 2014 V8-S. Even trying to search find capacities in my 26,000+ page Shop manual is nearly impossible and in many cases, is not listed in those manuals. And I have been searching and searching for the common capacities: coolant, engine oil, diff fluid (although that one was listed in the Shop manual), trans fluid, etc.

Anyone have a good reference or link to these capacities that is ACCURATE and from Jaguar??

 

Nice choice of year and colour.

Screenshot of my Jag service manual. Refilling based on these values always gives me the 'filled' symbol on the dash. I've never gotten an overfill message using this volume of oil.

 

From my MY18 handbook:

Engine oil refill and filter change - AWD 6.5 litres, RWD 7.25 litres.

 

Yep, on a RWD F-Type both V8 and V6 the correct engine oil fill amount is most definitely 7.25 litres = 7.66 US quarts.
I have changed the oil about a dozen times now on the F-Type and every single time I have added exactly 7.25 litres and the oil level has never read anything other than smack on the Max mark.

 

Thanks jpl500! Yes, sounds like we have 2014 samies. I'm really pumped about this car and I know it will be a great one when we get all the preventative kinks out of it. Had only 22 miles and an older 2 owners, so I think its a keeper. I have ordered the original owners manual that was lost along the way. Hopefully that will give some good solid info as well.

After seeing your numbers, I always wonder, so what happens with the difference from 8.9 liters (initial fill) and the routine oil change amounts of 7.25L... and difference of 1.75 liters or 1.85 QUARTS!! My physics class taught me "matter is neither created nor destroyed". So I am wondering, is 1.75 quarts floating around and that amount always remains in the engine??? (Things that make you go hummmm).

I noticed were a "B" owner at one point. A man after my own heart.... here's my 1973 MGB with only 32k original miles-- and all stock except the wheels and respray. My first roadster in college was a B and I've always loved them. How far we've come with the F-Type in comparison, eh?? Unreal!

 

Yep, that extra 1.65 litres is in the engine, in the oil galleries.

Beautiful MGB. I bought one new in 1974 and drove it as my daily car for 31 years, winter and summer. Abominable build quality (British Leyland days, and the Jags built under British Leyland in the 70’s were almost as poorly built, providing the basis for the continuing myth about Jaguar quality). But mechanically, that MGB was a gem, and tons of fun.
