Can you do me a favor then? Next time you have your oil changed(or if you do it)could you make it a point to get the part number for me? It'd be much appreciated, by me and many other Zetec owners. If it does in fact exist I'd like to try one and see how it does.

Please keep in mind that I certainly wasn't placing blame or calling you ignorant. But, as you said, there is definately a descrepency(shut up Joe)here that should be sorted out. Good luck. No hard feelings I hope.
