Dino with best cold starting properties?

[Garak]

Absolutely. I've ran all kinds of 5w30 conventional oils in the winter with few complaints. If the battery isn't up to par, the oil won't help much.

this was a sarcastic comment and not meant to be taken completely serious, evidently it was in bad taste and my apologies to the op.
i have no data to bring to the table, all i have is internet propaganda, some of which has come from this very site. i have never run used oil nor would i, with that being said one could argue that alot of( still good) oil gets drained.

That comment make very little sense. What benefit would using synthetic bring to this guy's neighbor? If you can bring some data to the table not internet propaganda I would entrain your argument.

Did the oil & filter change for him yesterday. Motor is smooth and quiet, didn't expect anything different. He now has a couple 5qt jugs of Mobil oil sitting next to his Hyundai oil filters on the shelf ready to go for the next change. Thanks to everyone here for the advice given!

The Valvoline 5w20 conventional has good cold capabilities.

Most 5W oils are certified down to minus 35C, but the engine manufacturers recommend a 0W oil below minus 25C. Engines do start more easily on 0W oils and that means the battery and alternator will last longer.

Within reason. Only some manufacturers actually recommend 0w-XX oils, regardless of weather. Sure, a lot of the European ones and some Japanese ones, do, but plenty do not. In any case, I've had no problems with 5w30 in -40 over many, many years.
