Turbo Coupe Oil

I would use as low a weight as you can use without having problems. If youre engine doesnt leak, then 5w30 if not 5w20. It does help economy, and probably performance too. Thinner oil = less resistance, "freer" engine.
Another thing, if youre gonna use synthetic, and you SHOULD, make sure you run synthetic diesel oil. Regular synthetic doesnt have the zinc and ash? our stock slider cams need. I had been running supertech synthetic in my car for 3 years and when my motor blew and I took it apart the cam and followers were wiped. Thats when I learned about the whole synthetic and slider controversy.
