Dealer says 0-20 oil

2013 dbl cab v6. Talking with the dealer the other day and they said Toyota now says 0-20 oil in the v6 instead of the 5-30. I tried looking into this and cant find any facts on it. Anyone else hear of this?

 

What does your Owner's Manual say?

 

Lighter weight for colder climate?

 

I've heard nothing of the sort for the 4.0, although I don't think I would have too much of a problem running 0w-20,,, although I doubt I would do it without some firm documentation from Toyota or an actual oil pressure gauge.

 

Manual states 5w30...I bought the platinum warranty partially becuse is came with 8 free oil changes and the dealership told me it took synthetic...but when i took it in for a change they told me it took regular and if i wanted to upgrade to 0-20 mobil 1 and i would have to pay the difference which was more than i wanted too...

 

Look on your oil filler cap.

 

The dealer here changed all their bulk oil over to 0w20 5+ years ago. They put it in everything made since 2000 I believe.
