Check out the oil viscosity Toyota uses in the 5VZ. Also check out the change interval. Keep in mind this with conventional dino oil. Interesting.
I dropped off a sample from my oil change yesterday to a local lab I just found. The oil was Mobil 1 0w-40 'Euro Spec'. The interval was 7k miles. I'll post the report from the analysis when I get it, should be tomorrow.
