OK---so I took some advil and got under there and changed it Saturday. The 2010 Mazda 3 has a splash guard that had a hole that is 'right handed' meaning it is open directly below the filter and has some extra space to the right of the filter so a right hander can get a filter wrench in there, or in my case a ratchet. It hurt like a bugger with my thumb but I did it with a ratchet, extension and one of those 3/8 inch drive filter cap things I just happened to have laying around.
The only issue was that I DROPPED THE FILTER JUST AFTER I UNSCREWED IT AND IT LANDED ON THE SPLASH GUARD AND SPILLED ALL OVER IT. I should have used my left hand to unscrew the loosened filter the rest of the way but got lazy and didn't move over. Anyway there are a ton of indents in the slash guard and I spend the next half hour and 3 old towels reaching in the hole and cleaning out all the oil that was sitting in there. Felt like a TOTAL NOOB. I usually remove the splash guard to do the OC, but with the thumb decided to try with it on. Well at least I'm still good with the warranty------------!
