Thats a pretty cool gadget. I just bought my XF a couple weeks ago and I bought the stuff to do an oil change today. I bought a Fran oil filter? Is that OK. The guy told me Fran makes most of the OEM filters for the car companies and he said Fran makes as good of a filter as there is so I bought it for $11.00 but I didn't put it in yet. Please let me know if is ok to use a Fran Filter please thanks. You seem to know a lot about oil changes. Thanks again
