Which oil to use?

I've had my 7 for 5 years to be soon and have been using either BMW oil or lately Mobil1 0w-40. I know that BMW recommend Long Life oils only which are very limited to choose from. Everything I've used poors like water and I'm concerned about its ability to protect the engine especially having almost 130k miles on it. Did anybody use anything higher than 0w or 5w? Does it make any difference on the car's performance, funcionality?
