I wouldn't mind doing it every 5K at all which would be about once a year, just trying to justify a 10k cycle which would push 2 years, although 2 years seems quite long.

It's 10k miles or 1 year which ever comes first as stated in the owners manual. 2 years on the same oil is way too long to the point you risk serious oxidation. I don't recommend the 10k mile change even. Remember toyota is in the business of selling cars, as long as it gets past the warranty period that's all they care about. I recommend changing every 4-5k miles. If you want to push it further take a sample and send it to blackstone labs then start pushing up 1k increments as long as you get the same wear levels. Remember everyone drives in different conditions and wear levels will differ between cars. I like using fram ultra filters too as I find the oem Toyota filters on the cheap side
