Which engine oil is best?

I am putting back together my 4G63T engine very soon and i'm considering what engine oil to run. I was thinking something that is full synthetic but is that bad in a turbo engine? I'm thinking about Mobil 1 or Valvoline, what is best or do you have any other suggestions? What weight would be best? I was thinking like 5W-30 but I don't know i'm kinda new to the 4cyl. turbo engines. Any input would be great!

mobile 1 10w 30 is what i use cuz its the best for my car. mobile 1 is the best out there and in weather over 38 degrees 10w 30 is best

holy obnoxious sig text batman

the weight is for the temperature. people use 5w30 or 10w30

On a turbo car you tend to want higher weights, since we beat the shit out of parts. And the turbo beats the shit out of the oil (there is a reason all turbo DSMs came with a factory oil cooler). I wouldnt run 5w even in the winter. 10wXX Mobil 1 is probably one of the most popular synthetics used in dSMs from what I have seen. I run regular old penzoil 10x30 or 40, whatever is on sale. I have no problems with parts wearing, so I'm sure any synthetic will do fine.

From my experience, I would go with Royal Purple, Amsoil, or a Lucas additive. They have also kept the temperature under my hood down after racing. I also recommend 5w30 in the winter and 10w30 in the summer. (Just posting what has worked best for me)
