I don't put many miles on mine, right at 5k last year (managed to keep it just under so I could skip emissions inspection).
I use Purolator 1 filters, and Castrol synth. It's been, um, more than a year.
I'm going to send it off for analysis, changing it tomorrow. Last time I sent it off at 5k the test came back near perfect. It wasn't even black, still looked the same as when I put it in.
