We've had aviation mechanics tell us to put MMO in our airplane fuel to keep the valves from getting caked up with lead deposits from the low lead fuel we have to put through that engine. It works!

We used to own a Piper Pa-22-160 with the Lycoming O-320 B2A engine.  My flight examiner, Catherine Hiller, told me to swap out the spark plugs, top for bottom, every oil change or when the mag-drop became interesting.

Don't worry about your injectors wearing out or failing.  Do worry about particle contamination, so good oil filters and scrupulous attention to cleanliness when changing them out.

Lynn and I worked for a Tier II auto manufacturer making among other things Bosch injectors.  The only was we could meet the fit an finish requirements for the valve body was by inspecting every single bore for fit and finish.  The second generation of measuring machine we built hit the sweet spot for speed, accuracy and documentation.  Just so long as the operators didn't ship the test samples to the customer.
