Please use the search function found in the upper right hand corner of the page. There have been countless threads on those very things.

Basicly what you will find, will be in tank fuel injection cleaners only work if your injectors are slightly to not at all dirty.

And the best oil for you engine will depend on your pocket book and driving conditions.
