Others do so every day, however, and report clean engines and long engine life.
Why do you think you need to do anything beyond continuing your current change regimen?
It runs too good for me to suspect any sludge or significant buildup. I'm just thinking long-term. Good suggestion on a higher mileage syn though. Believe me - I want to leave "well enough alone" but wanted to get some feedback. I certainly trust now that over the course of 55k miles - my engine has been cleaned pretty well by the Syn.
