Any recommendation on those combinations? The car also leaks oil once warmed up to hot. for this purpose I was thinking 20W50, but read that 15W40 is better with keeping oil temps consistently lower. Any suggestions?
Also cant decide on either of the brand.

Either brand is fine. Buy the one that is availabe or suits your wallet.
Here in Oregon we have similar weather, I run, 20W-50 year round.
