Hey all,

There is a chance that I am just a complete idiot, but bear with me and some of you might be shaking violently by the end of this.

(important new update) - while not guaranteed, tuner confirms very little apparent damage to engine. We are a touch sluggish but he is confident it's a non event. I can certainly hear and feel it after pushing the car really hard on big runs, but we will have to just wait and see how she looks during the tear down coming soon)
In case anyone has dug really deep, I am sure all of you by now have seen the service bulletin on Topix that the mechanics use to service the oil in our cars. Since 2014 it has been clear that 7.25 liters services a full oil change and filter change in a 5.0 supercharhed. This comes out to around 8 quarts since ethereal mechanics figure a little oil burn.

This has been updated and shows in the 2015 release. So what's so scary about the?

Suprise, your six figure R AWD that you had the dealer change the oil in early has been riding around with 2 quarts too many and probably has a shot engine.

The new AWD R's, with filter, must not be given more than 6.5 quarts. Jaguar, while putting it in the manual, has failed to update topix and have not informed the mechanics.

I had the two top people at my dealership try to talk me out of the facts and eventually look at each other in disbelieve as they came to terms with the fact that they will be replacing my engine (I had them do it for the warranty end, bad call me!)

Check your manuals, and in case you got a dealer oil change, call and ask the dealer how much oil they put in last time before you tell them why your asking.

I am trying to make a huge fuss about this now because I don't want this entire forum to become even a big complaint board for 16 r owners with blown engines.(winky smiley or something)

Isn't there an overfill sensor?

 

You check your engine oil every week as stated in the manual, right?

 

Wow and that's defiantly overfilling it to much. I just had my first oil change done but mine is a 2015 S so hopefully they didn't overfill mine. I'm going to have to check it when I get home to be safe. I'm not even sure how to check the oil level in this car but I'm sure its in my manual. Thanks for the headsup Chris.

 

In the past half century of putting oil in cars, I've only used the spec'd capacity to figure out how much oil to buy. I don't think any trained mechanic puts in a specified amount without checking the level before the final quart goes in.

Now, if the level sensor is off by more than a half quart, you'd have something to talk about.

 

RI check the oil daily almost and change the oil/filter myself every 3k miles otherwise. Problem is just a few miles while over filled that much can cause permanent damage I would think. And surprisingly enough, thetc car does not have a overfill warning, it will only tell you if your overfill if you go and check the electronic dips tick through the rediculous process they have. I did do that thankfully and found it, but no, you wouldn't know until you had a problem otherwise.

 

The head mechanic said that they pump in exactly 8 quarts and that is that. No checking it. They said also that they think the cars electronic dips tick is flawed and usually wrong by more than just .5 quarts. He virtually dismissed the thing all together and said ignore it.

Scary now? Can anyone else see that this might actually be a jaguar corporate oversight?

 

Think again....



This 2014 model had just came back from a dealer service and it was only by absolute luck that the owner saw this message as he had the bonnet up during a clean.

Idiots had put in at least 1 litre too much.

 

Well, I found one last week who obviously does and worse. I took my less than 1 year old Jeep to the selling dealer last week for it's first and early oil change. I always check the level when I get home, and when I checked the dipstick it was more than a quart overfilled. I took pictures of the dipstick clearly showing the overfill.

I took it back the next morning, and they apologized and said they had drained it to the right level. I checked it again once home, and it was still at least a half quart overfilled.

Talked to the Service Manager who apologized again, and said they were going to fully drain it and put in the specified amount of new oil while I was standing there supervising. They weren't using bulk oil, which they don't use for full synthetic, which this engine requires. After watching him put in the specified 6 qts. it was dead on the full mark on the dipstick--only took 3 trips to get a proper oil change. They admitted it was more than a quart overfilled and documented that on a new service ticket.

Unfortunately, carelessness is still common at dealerships, and I always check their work.

With regard to this thread, I find it hard to believe that the AWD version calls for less oil than the RWD, since it's an identical engine, but who knows . . .

 

My understanding is that permanent damage doesn't occur w/ a 1-2 qt overfill unless it is driven many miles in that state. That's why it's important to check it after every oil change.

You did, and I think you'll be OK.

 

Having absolutely no knowledge about the AWD version (which of course makes me an expert) it wouldn't surprise me if the oil pan is shaped differently.

 

Coincidentally, if you view the you tube video on how to check the oil level in an F-type put there by a Jaguar dealer, you'll see the oil level is overfilled. This is the fundamental easy stuff and gets me wondering about how complex issues are handled.

 

Yep, shortly after I posted I had the same thought. JLR has documented that it's mounted higher to accommodate the front differential, and the hood had to be re-designed w/ a bigger bulge as a result, which is why the hood vents are in a different location.

Thus, it's quite plausible that the AWD oil pan has a carve out for mounting purposes giving it a bit less capacity.

 

I've been in the aviation safety/accident investigation business for 36 years. It is a striking pattern in most incidents and accidents that it is usually the little things that cause complacency and set the accident sequence in motion. On the other hand, catastrophic mechanical failures almost always have happy endings.

Similarly, oil changes are ridiculously easy and prone to complacency and lapses of attention, but a transmission rebuild tends to command a lot more attention.

It's a characteristic flaw of humans doing boring jobs.

 

I just had this EXACT thing happen to me 3 weeks ago. I took my Type R in for it's 1st oil change at 3000 miles. The dealer put in the specified amount then added a 1/2 quart for the filter change. I drove it 110 miles. After sitting in my garage for a few days, I checked the level before starting. It was overfilled! I had Jaguar flatbed it 65 miles back to the dealer. I witness the dealer suck all of the oil out and measured it. Exactly 1/2 quart over. The engine is fine. But this is apparently common practice so I guess that many F Type owners are driving around with too much oil.

 

This is just plain sad! Whatever happened to pride in workmanship??

 

An update: I just had the lead mechanic at my local dealer (different dealer than the one that overfilled my car earlier) check online w/ Jaguar. The capacity listed in the owner's manual on page 223 is incorrect. The correct amount is still 7.25 liters.
There is a paragraph right below the chart that says: "The quoted capacities are approximate and provided as a guide only. All levels must be checked using the level marks or information displayed in the message center."

So....check your oil level off of the message center and you'll be fine.

 

Of course, they are. That's always been the case with any car.

 

7.25 Liters = 7.66 US Quarts. So how does a Dealership actually measure how much they are putting in? Do they open 8 quart Bottles and add approximately seven and a half of them ? Or do they buy their Oil in 55 Gallon Drums? If they do, then how is their Pump equipment calibrated?

If all the old Oil isn't completely sucked out there could also be a chance of an overfill .

I think it might be a good idea to check the Oil level before leaving the Dealership .

 

Let me remind everyone else that the R AWD asks for 6.5 not 7.25, so your lucky they only put in 7!

I was 2 quarts over twice and put on about 250 miles in total in the overfill ed state.

Update: the complaint is slowly clmbing the chainext of command. We should all know it's been resolved when topix shuts down for a day, the workshop manual chapter on oil changes it inaccessible and all of a sudden the dealer is calling you to come in a swap some unimportant accessory.


SUPER UPDATE:
Apparently despite all the indications, sounds and noises to the contrary, the engine is perfectly fine.I was almost quietly escorted out once it was finished but insisted I see the nechanic. He nervously seemed to indicate it was fine.

I am going to follow up on this daily until I get an answer fromy him on what corporate says.

I'm pretty disappointed so far. This dealer clearly doesn't usually get owners who can at least pop a good

On a side note, the dealer GM and most the guys around the shop do seem genuinely nice. I like to believe this is just an oversight.

Chris.
