The reason I ask:
I have been using Castrol Edge 5w30 in our 2007 Prius since last year.
My supply of the Castrol is about to run out, so I have been topping off with PU 0w40...which works fine. The question I have is: my next full OCI, should I just switch to my stash of PU 0w40, once the Edge runs out?
It is getting warmer here, not sure how much that will affect the weight.
Thoughts?
Thanks,
GL
