Had an oil change about 2 weeks ago.

As always, I check all fluids and noticed the dipstick is at least an inch past the upper dot.

Car was cold, in garage over night.

My service record says that 7.7 quarts was used for the oil change and filter.

 

Not good imo....slight over is ok but this looks excessive....assume level "ish" when you checked it ? I do my own oil changes and if I see this I would be draining it off to where it should be...however it would appear you had somebody do it for you so....take it back and ask for it to be corrected. TS

 

The proper way to check the Jaguar oil level is to 'STOP ENGINE WAIT 1 MIN'
That has been printed on dipsticks all the way up to the X300.

It is no longer printed on the sticks but it still applies.

Sitting overnite, the oil drains into the pan. That is not the intended oil level.

There is also a TSB about the oil level in the X100.

That's what I thought.
However, the owner's manual states that the engine should be cold.

Mechanic says he put in 7.7

A quick Google search:

 

Jaguar disagree with you:



It is preferable to check the oil after the car has sat overnight and is completely cold.

 

OK wait 2 mins. Like the document says "Stop the engine and wait for a minimum of TWO Minutes". I always stop the engine and wait 1 min.
Jaguar increased the oil capacity by issuing a new dipstick. Nothing else was changed except the dipstick. Put the new dipstick in the older engines and call it good.

I'm sure they want the engine COLD so some idiot will not burn himself/herself.

mmm.. I've always checked mine cold and it shows right on the dot... I should recheck this - thanks for posting this information motorcarman

 

Not the first time the manual was wrong!

I have always checked the oil level after the engine has been running. What I do not understand is how one can over fill the oil level. If it calls for 7.7qts then you put in 6 and use the dipstick and figure out if you need a qt or a qt and a half. You just do not fill it with 7.7 qts. Because that is what the manual calls for. The manual is not always correct!

Sorry for being so blunt but this is not the first time and I hope it is the last time…

 

If you've fitted the replacement dipstick, Jaguar specifies 8 quarts of oil.


Just my observation added to the discussion.

 

I think you missed the point of my post - I wasn't correcting you on the number of minutes that one should wait, but rather that you stated:

Your suggestion that the OP had made an error by checking the car when cold was misleading - when the oil has drained into the pan it absolutely is the intended oil level.

 

Yep...always checked the oil level with the engine cold and be sat overnight. I can't think of any better way for the oil to be back in the sump..after all it had all night to get there !!!
Done it this was on all my cars since 1979 and haven't seen an engine blow yet through lack of oil. TS

 

I would be very worried with the oil level an inch above full, "especially" if the newer dipstick has been installed.


When I bought my car (with 100K miles on it) the engine was burning a bit of oil, but other than a random "tick" now and then, it ran fabulously. 30,000 miles later it suffered a catastrophic bottom end bearing failure which required installing another engine ($$$).


I believe the IPO must have been over filling the sump to offset the oil consumption and this led to oil foaming, which destroyed my bearings.


Ideally, I now check my oil with the engine having sat overnight and NEVER fill above the top dot. I've put 70,000 miles on the 50,000 mile engine that was installed (120,000 total engine miles) with no problems since.


Over filling and oil foaming are huge risks.

 

I've been checking the oil in all of our vehicles first thing in the morning after the car sits overnight. Been doing it this way since 1969 and I'm far too set in my ways to change that procedure now....

My wife's 2006 XK8 takes exactly 8 quarts to read at the "full" hole on the dipstick and I never vary from that....

 

Photo 1 was taken before the car was started and it had been sitting overnight.

Photo 2 was taken only after 3 min of run time. As you can see how critical it is to have the proper level of oil in the car.

Photo 3 was taken only 5 min of operation

Photo 4 this was taken after the engine had reached operating temperature and sat for a minute or two.

In looking at the relationship of oil on the dipstick from a cold engine to a hot engine it was different but not by a lot but it was different. Because of the high oil usage on a cold engine I would be checking it on a hot engine. That little bit could make a difference on a cold startup.

Good post Gus!

 

The things indeed! Thanks.
