2008Yaris w/ 131000km due for oil change.Conventional or synthetic?Change filter too?

After spending a good deal of time over at bobistheoilguy, trying to get to the bottom of the oil mystery, The best oils are:

1. Redline
2. Amsoil
3. Royal Purple.

In that order. Everything else competes for lousy slots that are somewhat distant from these top 3. For a filter, the Royal Purple brand oil filter is top notch. IIRC it filters down to 3 microns. Not a whole lot is going to get past that. Due to the other 2 costing more, I have always ran Royal Purple in our Yaris and it has 200k on it. With royal purple filters. I run the oil for 7500 miles before changing it.

I've always ran RP with OEM filter. Due to lack of availability, I switched a couple years ago to AmsOil, and also tried their EK filters and seems to be great.

Anyways, I went back to OEM filters for cost reason.
