I currently have just over 140,000 miles my 08 and have changed the oil over 25 times on this one. I use the Motorcraft filter and the Motorcraft semi synthetic oil and have never had any problems. I use the same on my other 3 liter Ford which is now around 160,000 miles. Iíll probably be close to 180,000 miles when I get rid of my 08 Focus. The one thing that I do when I change the oil is poke a hole in the filter to keep down the mess when I unscrew it.
Nice contribution. Thanks!
