Did first oil change (by myself). Word of caution...don't leave the oil pan underneath when driving off the car ramps! I crushed the large kitty litter pan and spilled a good amount of oil on the driveway, jeez.. Long story short: I had one of those magnetic drain plugs (trace of carbon black residue on it). About the drain plug: Back and forth several times to Pep Boys. First I tried an 8mm thinking it was same as OEM drain plug, nope....returned it for a 10mm (just on a hunch) nope...then said hell with it and bought a set of allen sockets and found the 9mm was the one! And hard to believe this little 2.5L takes 9 quarts. I also cut open the filter...not a single trace of metal particles. Just turned 128k miles...
