That said regular changes are generally sufficient but I eyeball my oil choice sideways every so often after being quietly screwed by m1.
Reading up on 0w20 is interesting. In the end I opted for edge with Toyota filters. A pair of 5 quart bottles ran me a bit over $50 via prime. Another bottle will give me two oil changes easy.

I'm also not a big fan of Mobil 1, although I haven't tried the 0W-20. My experience is with Volkswagens and VW 502 spec oil. I've used both Mobil 1 0W-40 and Castrol Edge 0W-40, and the car definitely runs smoother and quieter on the Castrol which seems to be a bit thicker and doesn't shear down as quickly. Both oils are simarly priced. I'll probably stick with Edge when I get my 4Runner.
