Can anybody tell me the part number for the oil level sensor. The morons at the last garage I used managed to break it and didn't have the part to replace. Suffice to say it wasn't a Jaguar Dealer. I've tried looking on ebay for general Jag XJ oil level sensor and all it comes up with is this: 6PR 009 622-081 HELLA Sensor engine oil level for the statuesque price of £87! Oh to have a good old fashioned dipstick!

 

May want to try:

HELLA Sensor, engine oil level 6PR 009 622-081 | eBay

Appears to be cheaper than what you have found.

Or, if you are after the factory (OEM) unit, you can try:

JAGUAR OEM 11-16 XJ-Oil Fluid Level Sensor AJ812432 | eBay

This should still be cheaper than what you found if I remember my money conversions correctly.

 

How did they manage to break that? Isn't it inside the engine? I hope you aren't having a shop do your oil changes!

 

How in the heck do they break this?







Genuine Part # - AJ812432

 

Is your shop aware that the oil is changed (vacuumed out) from the top of the engine?

 

I know it might be hard to believe, but there are a lot of shops out there that do not have a vacuum pump to suck the oil out that are not regular high end car places. So, they end up dropping the plate under the car and accessing the drain plug like other vehicles.

I know I had a reputable place change the oil in my car that had no idea that they could suck the oil out of the engine. They kinda looked at me like I was growing a horn out of my head. I showed them the tube and they were all a little surprised. they said that they were just going to drop the plate on the underside and go after the drain plug that way. Granted, this was in "small town Ohio". So, me pulling in there with a Jag kinda had all the techs in wonder. But, the owner came out and told me that he was going to personally look over this oil change. I was nice enough to supply them with the oil filter (brought it with me because I knew I would need the oil changed after my long drive) and also the instructions on how to do the live read of the oil level so they could fill the car to the proper level.

 

What concerns me is there is a 100% chance that they do not have the correct oil. Granted, another type of oil will work, and if your warranty is out no real issue, just saying.

BTW: I got an oil vacuum from Amazon for $35.

 

IMHO oil is critical. When you have a recommended oil change interval of 16k going on the cheep will result in premature engine failure. Recently we have seen several owners whose engines have failed and I'll bet that was a result of some previous owner not having the proper spec oil in the engine. Really, think these engines have very close tolerances and orifices and are designed to work properly when the correct lubricant is used. At present I am at 78k+ and my engine is running as smooth as ever. While I do change oil @ 7.5 to 8k intervals I go to my dealer and rely on them as they use what is recommended.

 

XJsss, I am like you. I cannot imagine letting my engine run on the same oil for 10K+ miles. I change my oil every 7.5K miles too. Granted, I do my own oil changes and make sure to get the correct oil so I know the oil changes are done correct. I only had this shop do the oil change as I knew they would do things correctly and I made sure they had all the correct info to ensure the correct stuff was used.

 

Can you point us to one documented example?

 

Mikey take a look at some of the recent X351 threads where there have been catastrophic engine failures. Almost all if not all were purchased second hand with low to reasonable mileage at "great" prices and, I believe, you will have your answer. In one the timing chain was the issue. The tensions are Olio/mechanical. So with the proper oil the tensioner has oil pressure to tighten and then when it moves far enough it mechanically moves to the next "cog" to maintain tension. Just my long time Jag owner point of view.

 

I've read them all. Not one has any shred of evidence that the incorrect oil - type/viscosity/ interval was used or that such an error might have contributed to the issue.

 

My observation was based on talking to the lead tech at my dealer, who had a strong opinion that these engines are extremely reliable if they are taken care of and properly serviced they are not failing. The ones that they see with engine failure have all had a checkered past. So my "evidence" is based on discussions and observations only. Thankfully not on personal experience.

 

If the oil level sensing device fails how do you know you are low on oil since you cannot check it with a dip stick?

 

I intend on changing oil at 7500-8000 intervals with the oil that Jaguar specifies. I do believe that the oil will be cheaper than a 3.0 liter supercharged V6 just like the oil was cheaper than any of the Ford motors I have had.

 

If you use Jag specified oil, it is $10/quart.

 

Cheaper than the Amsoil 10W40 that I use in the bikes which is $12.99 a quart. We change oil in the track bike with filter every 500 miles. If you wants to play you gots to pay.

 

I, for one, am not going to risk an engine to save a few bucks by using cheap oil. That's just stupid.

I don't know how much "better" it is than any quality tier 1 synthetic oil. It was developed by Castrol and Jag specifically for Jag (go figure, another British company!) - But, I found and bought 2 cases of it. It is actually fairly hard to find but I got it from an ebay seller. It is the M2C925-A/B spec that is near impossible to find. It is rated for 15k miles I think but I don't think you should go that long between oil changes. And it does have a UV dye in it so Jaguar knows if you are not using it.

 

Castrol has stated that present production version of this oil no longer has the dye in it.
