When your in the US go to the nearest Mazda dealership and pick up as much Mazda with Moly 0w20 that you can find.
221VI with over 600ppm of moly and 40cst of 35, ILSAC GF5 SN. You can't go wrong and it's specced for skyactiv.
TGMO 0w20 will serve you just as well to and is available in Canada for quite cheap. Bring a 5L jug to a Lexus dealership and they will charge about $4.90-$5 per litre to fill it.
Enjoy the car once you get it.
