I had Green Oil in mine, not an issue there.
It will help if it is really cold. You will notice the engine revving lower when cold as it does not have to work as hard.
It makes little difference compared to regular 0W20 in summer.
Don't pay more than $15 extra for the Green Oil (compared to 0W20) as you will not earn it back. It can save you half a tank of gas over its life, tops.
If you were in Anchorage instead of Atlanta it would be a different story
