Change it exactly as listed in your owners manual.
it should be 7.9 qts i just finished changing mine tonight
5w-30 is recommended but you can use 0w-30 as well. You can also use synthetic oil if you wish but it is not needed.
jaguar recommends 5w30
7.5 litres
3 litres
The inline Jaguar 4.0 engine uses 8 quarts of oil. This is true for the supercharged XJR as well. This series or XJ300 model by Jaguar using the inline or straight 6 all use this many quarts Be prepared if you take it in to any shop for an oil change since their pricing only applies to vehicles using up to 5 quarts so be prepared to bring in 3 additional quarts and they will pour them in without charge. I do this on occassion when I don't have time to do my own oil change. Dave (Las Vegas)
7 quarts
I do believe that the oil sensor in a 1996 Jaguar tells you how much oil you have and it tells you the oil temperature.
not at all just take it to quick fit
5W30 weight
What type oil does what take?? The correct weight oil is listed in the owner's manual. Brand is your choice.
