MMO is an ancient remedy and does not work well with the modern oil additive package and will likely do more harm than good.

The safest way to get an engine flushed and keep it that way is to use one of the oils I indicate or any other CI4 rated oil. Once the engine is cleaned out use your favorite premium oil with ADEQUATE oil change interval.

Thanks for your post and have a great day,
