All new cars and certain rebult engines use a cylinder honing technique 
called Plateau Honing. This method makes the cylinders like those of a broken-in 
engine so that when first started the rings are already seated. This is a MUST 
on new cars which must meet emissions standards upon first starting. That is 
why they can use synthetic oil.
