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.
What kind of oil should I put in my XJ engine?
There is no point in putting very thin, exotic synthetic oils such as Mobil 0-10 in the XJ engines. The engine will be noisier and leak more. There is no great harm in mixing fresh oil, so while all V12 engines will leave KWE with 20-50 in them topping up with 10-40, 10-50 or 10-60 is acceptable if 20-50 can’t be found.

Why does my Jaguar XJS have poor fuel economy?
In summary, the fuel filter sold for the model was not manufactured to suit Honeywell’s specifics resulting in incorrect placement of the O-ring on the fuel line. Automatically, inadequate sealing will lead to leaking of oil out of the engine. Apart from being a fire hazard leaking fuel is a major cause of poor fuel economy.

What kind of engine does a Jaguar XJ12 have?
The simplest incarnation was in the carburettor fed E Type and XJ12 models, but the engine was designed for fuel injection from the start, and as soon as a suitable system was available it was fitted to the XJ12, the XJ-S was injected from the start.
