Hi this might be a reaally stupid question, but after looking at the manual and doing some google searches i cannot find anu useful info. Im trying to change the engine oil in my XJ but cannot work out which is the drain plug? Theres a square section under the motor (sump?) and has a bolt in the bottom, in the centre (looks like a torx bolt or something)...is this it?
Im scared to remove something i shouldnt...
thanks
