Another question thats probably already been answered but I didnt see it. Could I benifit from using 2-stroke oil in my 05 6.0 powerstroke?

It doesn't hurt it... But it will keep the fuel system lubed up and retard wear of fuel system related parts. The few times I've used it on a 6.0L you won't notice a huge change but it should become more quiter and a bit smoother running...

The 6.0H's still had the HEUI injection system in them which required engine oil pressure for them the fire. It still couldn't hurt to put some lube in the fuel which will help the innerds of those injectors!!!:2cents:
