What to do if your Jaguar XJS has an oil leak?
Note: Engine oil leaks from around the unit are commonly encountered; at each service check for and rectify such leaks before they can result in a serious loss of lubricant. Transmission lubrication: At each service, with the vehicle horizontal, check the lubricant levels in the automatic gearbox and the differential.
How often should I Change my Jaguar XJS engine?
At every service, apply injector/fuel system cleaner, then check the idle speed, which should be 750±25 rpm. Engine oil: Ideally, change the oil and renew the filter at least every 3000 miles or annually (whichever comes first), having first taken the car for a run to warm the oil and aid flow from the sump.The sump plug requires a 7/8in.
How often do you change the differential oil on a Jaguar XJ?
Every 20,000 miles (approximately), drain the final drive unit (after a run, when the oil is warm and flows more easily) and re-fill with fresh lubricant. Differential oil: Duckhams Hypoid 90DL or equivalent (a lube specifically intended for limited slip differentials). Differential oil capacity (approx.): 2.75 pints (1.6 litres).
How to fill a rear differential in a Jaguar?
Remember to wipe away the crusty road dirt before removing the plug. After the plug is out put your finger into the hole… you should feel the differential oil right at the bottom of the opening. If you don’t, top off the oil until it reaches the bottom of the filler hole. Overfilling only aerates the oil, reducing it’s effectiveness.
How often do you change the air filter on a Jaguar XJS?
HE units: 18 degrees BTDC @ 3000 rpm, with vacuum pipe disconnected. Every 5000 miles or annually (whichever comes first), check the state of the air filter elements (one for each cylinder bank, and fairly easy to reach; the filter housing lids are secured by ‘over centre’ type clips), renewing if visibly dirty.

What kind of oil does a Jaguar V12 take?
The Jaguar V12 engine and all 6 cylinder engines before the AJ6 engine of 1980’s vintage needed quite a thick oil – usually 20W-50 – partly because the engineering tolerances were not so close as they are today with modern manufacturing methods, and one needed a good thick oil to fill up those tolerances.
