How long have you ever gone between oil changes?

I'm totally in favor and recommend anyone to change the oil between 3k and 5k especially if you utilize a aftermarket "performance" filter. IMO there good for nothing but making a intake noise..unless you have a forced induction system or a modified cam intake set up.

Just so you know, it's not just 'your opinion'. Those filters do a very poor job of filtration. Cummins (diesel engine manufacturer) has come out with a TSB against them. Their capacity is lower than a stock cellulose and their efficiency is lower too. I'd recommend an AMSOIL dry filter to replace your oiled filter. We use the same filtration technology that our U.S. Government uses on the M1 Abram tanks. If you tell me what your filter dims are, I can look up an AMSOIL 'universal' filter to replace it with & give you a price.

I've never seen metal in my Yaris oil! I'd start a used oil analysis regimen on that car post haste before you get in position where the engine fails.
