Favorite 0W-20 engine oil?

:
CX5
I've been thinking about buying ow -20 oil in bulk and was wondering what brands most people use and recommend?

I've seen Mobil 1 and Kirkland recommended but how about stuff like Quaker state? Are they okay? They are on sale right now for 14 dollars.
 
I have 7,000 miles on my cx5, NON turbo (which 0w20 is recommended for in the manual) . However, I finally just switched to 5w30 and ditched the 0w20. For MANY reasons, thats another thread topic though. Im not anti 0w20, I just feel its a better choice. Having said that, for the short time I DID use 0w20, I loved the Mazda oil eco7 0w20. I believe it still has a high dose of moly and is a really good oil. IF i was going to go BACK to 0w20, it would probably be pennzoil ultra platinum 0w20. Since the final choice i made on the 5w30 is pennzoil ultra platinum (i absolutely love this oil for the skyactiv) . A close second would be amsoil 0w20 or the Mazda, both considerably more expensive. I think all the oils you mentioned are decent, but if i had to pick between just the 3 you mentioned (quaker state, kirkland, mobil 1) I would choose Kirkland. Hope this helps.
