Euro C5/C6 same as ILSAC 0w20

Flow is largely irrelevant. The winter rating is about cranking and pumpability. If it pumps it will flow.

And this is determined by temperature. How cold is your coldest expected starting temperature? An oil with a 5W winter rating will be guaranteed to be pumpable down to about -30 or so, are you starting below that temperature?
It doesn't get too cold. I'm in Niagara area and vehicle is kept in garage. Unless I take it out, car gets short tripped by my wife. I was looking at Pennzoil Euro 0w30 but has no approval and API SN.
 
I think there is no difference between Euro C5/6 0w20 oil and ILSAC API SP. I see VOA on both and can't seem to find any difference. I know the 30 grade Euro oil has a HT/HS of 3.5 vs 3 but the 20 seems the same. Any thoughts?
SP contains a standardized LSPI and TGDI timing chain wear tests. These particular tests were adopted by the ACEA under C6.

Euro approvals have their own similar tests using their own engines.
