I finally got around to installing this today only to find that it most definitely DOES NOT fit on a 2012 Mazda 3. The threads are correct, but the lever portion makes contact well before the blue washer is seated properly. Yea I realize the crush washer is still in place in the picture, this was a test fit before bothering to pry the crush washer off.
This one is for my Ram 1500 when the first oil change comes up. Had one on my grand caravan. Makes DIY oil changes easy and stops garages from buggering drain bolt heads. Nice quality brass unit. Never had a drop of oil leak from my previous unit.
