I finally changed my oil today at 5000 miles, not the 7500 recommended. I went to walmart, got the Motorcraft 5W-20 synthetic blend, Ford filter and proceeded home to drain the hot oil. The fun started when I tried to get the old filter off. I tried a cap type filter wrench first, it kept slipping, then I tried a squeeze type clamp wrench. After partially crushing the filter, I still couldn't get enough leverage to turn it. Next I tried driving it off with a hammer and flat tip screwdriver, still didn't budge. Finally I used a 4" C-clamp tightened very tight with C on the bottom of the filter, I put a pry bar through the C and finally it turned and slowly untightened. I'm glad I didn't have to resort to the screwdriver driven through the filter, that's just way too messy. I don't anticipate the next oil change to be quite as hard, since I didn't ask "The Hulk" to tighten the new one for me. I put exactly 5 and 1/2 quarts in and that brought the level on the dipstick up to the correct level. I don't know why Ford put that filter on that tight, I guess they want you to give up and bring it back to the dealer, no way, I'm the only one that's going to touch my 2008 Copper Limited.
