Jaguar X-Type JJM 21 02 20/15 - Manual (Page 156)

7-6 Maintenance
Checking and replenishment
Check engine oil level
Check the oil level regularly with the vehicle on flat, level
ground.
Refer to page 7-5 for dipstick and oil filler locations.
It is preferable to check the oil level after the vehicle has been
standing, that is, with the engine completely cold.
If the engine has been started do not check the oil level until the
engine has reached normal operating temperature. Stop the
engine and wait for a minimum of 5 minutes to allow the oil to
drain back into the sump.
Remove the dipstick (A) and wipe clean with a non-fluffy cloth.
Replace fully, then withdraw the dipstick. If the oil level is above
the lower of the two dots on the dipstick then no additional oil
is required.
If the oil level reaches the lower of the two dots, remove the oil
filler cap (B) and add oil, to the quantity and specification
shown on the next page.
Refit the filler cap and hand tighten securely.
