change oil

I looked and didn't see this. I change the oil in my gas engines to the synthetic oils. I have 170,000 on my F350 7.3 and want to change it also. Is it Ok? is there a special synthetic to use? Nobody has had any problems going to the new oils have they?
Thanks
Lee

No not at all. I run 5w-40 rotella synthetic right now. You can run any diesel rated synthetic that meets CI-4 specs

Thanks guys, I went to this link and got totally confused.
Car Bibles : The Engine Oil Bible
I'm only getting 13 mpg mt or loaded, is there a way to get more mpg without too much loss of power?
