Is there any particular fuel treatment recommended for use in our cars to help prevent this problem?

I have only ever had "top tier" 91 and 100 octane fuel in my car, and make sure the oil is up to operating temperature (and then some) to minimize carbon deposits and still had injector failure. Not sure there is anything we can do short of replacing them when they fail.
