where i live we haven't had a winter where it got below -10 in quite a while, using 5w20 would it make any difference to use a synthetic or would dino flow just as good?
dino vs syn at -10

-10f is fine with fresh dino 5w30. Motorcraft, Havoline and PZ are very good in this regard.
That temp is not reason in itself to "need" synth, at all.

Not that i live in that type of cold but imo on the above
Dino 5w-20 is thicker in cold than 0w30 synth. Synth 5w-20 is thinner.
0w flows better than 5w which flows better than 10w
but how much flow do you need? cars are engineered for cold way better than we think
10w oils are tested at -25C which is -13F
5w oils are -30C or -22F
0w oils are -35C or -31F
these are just the CCS tests. the MRV tests are done at even colder temps
