A local franchise of an Oilcan Henry's lube chain tried to charge me extra for a basic lube and oil change 'cause they said that my (bone stock, mind you) XJ had "more than normal" zirk fittings to be greased. (It was real hot out and I didn't want to deal with changing the oil) Evidently their docs didn't match what they found. To their credit, at least they did grease the thing, but it took half an hour of heated discussion before they capitulated on the price. Obviously, I don't go there any more. I mention this because even the pictures in Haynes or Chilton's may be incorrect. Mine match my FSM, so I don't know what the source for their info was.
