My 07 RX is leased until 54K, so I use Mobile 5000 5W30 bought at walmart in the big 5Q jug for $9 and $2 extra for another quart since the car takes 6.4. I usually put in 6.2Q after an oil change.

In my Prius which I bought and will keep for awhile. I use Royal Purple 5W30 Synthetic. It uses real synthetic base oils unlike Mobil 1, so I switched.

5W40 is perfect for that, I know some guys who like the Castrol Syntec 5W40 for that reason, though some also like the Mobil 1 0W40.
