Just had oil changes in my 2010 Nissan Sentra and it is black already. It's only been about 3 weeks.

I'd recommend putting synthetic oil in your SE-R. If you have very cheap oil like Walmart's Tech2000 (which I've heard is recycled/filtered/re-refined used oil), you will not get the expected mileage. This said, get your oil tested if you suspect something is wrong. You'll know if there are debris in it or if your it's just burned up.
