This is the first UOA I've gotten on my wife's 2008 Mazda3 with the 2.3 liter engine and 5 speed manual transmission. The analyses I've gotten on my Civic have always been influenced by the makeup oil I've added, but this car doesn't need any so I wanted to get a UOA with TBN to confirm that I don't need to be getting nervous over 5k miles. The manual recommends 5000 mile OCIs for severe service and 7500 for normal. On my Honda (which gets similar driving patterns) the OLM puts me conservatively at 6000-6500 miles and it looks like that's valid for this car too (again, conservatively).
Here's another boring Motorcraft UOA:
