Keep in mind - there's nothing super special about Genuine Toyota / Lexus 0w20. Here in the US at least, we have an abundance of cheap, high quality synthetic* 0w20 oils available anywhere.
It's a perfectly good (maybe even great) oil, but so are Mobil 1, Pennzoil, Valvoline, etc.
* Synthetic is a slightly weird term, because most of our synthetic oils are still technically refined from crude, but with a special process that many experts say produce base oils that rival or sometimes outperform traditional synthetic Group IV and V oils. I say with a 5k mile oil change and normal driving, don't bother with the ultra high end "true synthetic" stuff from Amsoil / Redline / Royal Purple etc.
