I don’t do fluids because my cars are in a underground condo
garage, so I buy my 10W 30 Mobil One High Mileage, my filter, and
take it to a closeby shop that performs the change as I stand next
to the guy that is doing it.
So he takes filter of and I instruct him to let the car drain for a
while. He adds the 5 liter jug and then three lines (3 liters) of
the other 5 liter jug…total 8 liters. From cold, my dipstick is
3/4 of an inch above the full mark!!
Is the refill amount for the AJ16 not 8liters/8.5 quarts?? Even if
(and this is not the case) There would be 1/2 a quart more on thee,
the dipstick should not be that high.
Either the refill amount for an AJ16 is not 8.5 quarts or those
dipsticks are wrong.–

You left out the fact that after it drains, he installs the new filter,
which is EMPTY of any oil. He should then add 8.5 quarts of oil, which
all goes into the sump (still none in the filter). So at that point,
YES, the level will read high on the stick.
NOW, run the engine for ~ 30 seconds, turn it off and let it sit for ~
2 minutes. Now read the level on the stick, and you will see it has
dropped to the “hatched” range on the stick, as some of the oil which
was in the sump is now in the filter.

A procedure that I have adopted on all my engines when I
change a filter is to prefill the new filter with oil prior
to installing it on the engine. This provides pressurized
oil to the bearings as quickly as possible when the engine
is first started after the filter change. Without the
prefill, the first few seconds of running are without oil
pressure and a few more seconds probably have a high
percentage of air mixed with the oil.
I used to work for an engine bearing company and saw many
bearings that had suffered from oil starvation. I do not
have any test data that my procedure will add significantly
to engine life, but I feel that it can only help.

If I recall correctly, I believe the owners manual for the AJ16 (I
believe think the AJ6 and V12 as well) calls out 8 U.S. quarts
engine oil capacity. I change my oil every 7,500 miles - 8 quarts
of Mobil 1 15W50 with filling the oil filter. The dipstick may read
a little below absolute full, but not enough to make a difference.
I’ve done this through both V12 and my current '95 AJ16 and never
had any oil related problems. These motors are capable of very high
mileages with proper care and maintenance. I was changing my
transmission fluid and filter every 30,000 miles and just switched
to synthetic ATF with my change last spring (and one drain and
refill since and synthetic diff. oil. I’ll monitor and advise on my
service life of these synthetic fluids. The transmission shifts
feel smoother with the synthetic fluid…–

I would encourage AJ16 (1995 & 1996) XJ-S owners to check their Drivers
Handbook (glovebox-sized book that came with car originally) under
Fluids, Capacities, and see what the oil refill capacity is.
The August 1993 Jaguar Service Manual, Supplement to Volume 1, page
09-4 gives the refill capacity for the 4.0L model at 8.5 U.S. quarts,
and 10.5 quarts for the 5.3 & 6.0 V12.
If you only put 8 U.S. quarts in a 12 cylinder upon refill, you would
be risking serious damage, and the oil would not even appear on the
dipstick.

George, thanks for refreshing my memory about the V12 - t’s been

George:
The handbook does call for 10.5 US quarts oil, but when I
added 9 bottles Mobil 1, my dipstick showed full (after
running the engine for a minute and waited a few more
minutes to take the reading)…?
The handbook also says that the fuel tank capacity for the
1995 V12 convertible is 21.6 US gallons, but I have never
added more than 17 gallons with a solid yellow warning light
(there was a recent topic that covered it – half-way fill
is ca. 9 gallons).
The factory documentation also specifies 0.025’’ gaps for the
spark plugs, and I suppose this is also incorrect.

Well guys, I can assure you the car was drained and refilled as
usual, 8.5 quarts or 8 liters where added, and 5 days later, when
checking the oil level as I usually do, the oil is still 1 inch
above the full mark. It seems that this has not happened before!!
I hope I don’t break anything (doubt I will), but I also don’t want
to waste that very expensive Mobil One and just get it redone.
I was thinking that maybe the car was not warm enough at the time
of the oil change and not enough oil came out???

No, that one’s correct! And critical!

Drain. Never, never, never run with too much oil.
Too little, on the other hand, is far more acceptable. If the car
holds 8 litres, I wouldn’t have a problem running on level ground
with perhaps 3. So, rather than running into this problem again, why
don’t you just forget the manual and instead add perhaps 6 quarts,
run it for five minutes (any more is pointless), and then add until
the level is between the full and add marks on the dipstick?

It’s just very odd that it would happen to two people with
the same engine (AJ16). In the past I have bought 8 quarts
of Mobil One in separate bottles and the level always
showed right. Only difference is I bought 2 large 5 quart
containers this time and one was used fully and the other
had two full lines left of oil in it, hence the same 8 qrt
that are normally added where added this time around.
Either
A-car was not warm enough for all oil to come out
B-once you switch to Mobil 1, eight full quarts don’t come
out anymore (this is my third change since switching)

Just an ‘‘off the wall’’ idea. Is it possible that you have the
wrong dipstick installed from a PO? Why not post the measurements
and have others confirm yours is the same length?
Screwier things have happened in the past with our cars.

I doubt that it’s the wrong one. Jaguar lists the same
dipstick for the x300, xj40, and Aj6, and aj16 Xjs. I might
just get a new one for kicks.
I looked at some archives on the X300 forum (same AJ16
engine) and found the same issue.
Another poster with a AJ16 XJS as well has carved another
line on his dipstick.
I guess the important thing to figure out is if it’s more
important to refill the car with 8.5 qrt after the oil is
all drained and filter changed or follow the dipstick.–

Throw the 8.5 quart BS out the window, the level indicated by the
dipstick is what’s important. There’s a windage tray inside the
crankcase, and the level of the oil relative to this windage tray is
critical. It isn’t a big deal if the level is lower than the tray,
but it is IMPERATIVE that it not be higher.
If there’s any possibility that your dipstick has been replaced with
an incorrect one, I dunno what to tell you. I suppose there’s some
way to drop the oil pan and check where the dipstick sits, but I
dunno how to check it.
