Based on info I read here and elsewhere, I had been taking my Expedition to a Jiffy Lube. I decided to do it myself one day. I was able to reach up to the oil filter from beneath the vehicle. It was not nearly as difficult as I expected. It seems like there is a plastic diverter of some sort beneath it...if you let it drain slowly it doesn't make a mess. If you haven't already, I suggest doing the filter change yourself at least once. It might not be as difficult as you think and you could probably include it in the 5K OCI. You may not need 5K OCI depending on your drive cycle. Blackstone said my oil was in very good condition with 7,500 OCI.
