[QUOTE=95331140;2655875]Maybe it could be better for keeping the injectors cleaner for the long-term..[/QUOTE

I don't believe it would make a lot of difference to the injectors. That being said all injectors will eventually need cleaning & new "O" rings fitted, usually after well over 100,000km. I believe a lot will depend on driving style as well - a car that has been babied will carbon up the injectors sooner than an engine that is given a good workout from time to time.
