Postin this for a fellow XJ owner having trouble on the road. Any ideas what can be causing it to use up that much fuel?

That is about 4 mpg. I would at a minimum expect visible black smoke from the exhaust, especially under moderate acceleration if it's really burning that kind of gas.
I'd bet leak.

Well. If the plugs are really fouled, He's got a problem. If I had time, I'd start by checking if the O2 sensors were working, or that the air intake wasn't totally clogged by something.

Maybe I should of express my self a little better. I was replying to someone suggesting that the fuel was being siphoned while the XJ was parked. The excessive fuel consumption took place while on the HWY! When I last spoke to my buddy, he told me it was traced to a faulty O2 sensor. Thank for all the replies(even the smart *ss ones).
