When AT-205 is mixed with engine oil, it seems this mix become powerful piston ring cleaner.
Something that I consider more or the same effective as Kreen in oil, and definitely better than typical fuel system cleaner or Berryman combustion chamber cleaner.
Somewhat this is a pleasant surprise even though I am not sure how long the effect will last, so far I have got 1500 km and the effect is still noticeable (quiet engine with very responsive powerful engine). It seems it dissolve deposit left by LM MOS and LM MoS2.
However, wondering if someone has observe the same effect with AT-205 in engine oil ?
