- The land of USA-made Subies!
You’ve got it backwards; the oil itself is the stronger cleaner of the two… the EC is a “lite” version to begin to break down sludge & varnish at a slow rate for safety. The oil itself is formulated for maximum cleanliness and if used in a sludges engine may release large chunks of carbon or other accumulations that could plug the oil pickup or internal passages.One question I had for Dave, what ratio do you need to run the EC to get the same cleaning ability as the oil?
Straight HPL EC will not clean as quickly as straight HPL PCMO.
