When Restore was a new product, a 292 cu.in. ford Y-block with many miles as a test pig. Record compression. Change oil and add Restore as per directions--netted an increase in compression on all cylinders but what was most noticible was that the really low pressure cylinders were pulled back up to almost normal compression. Now IF diesel engines react the same as gassers, and IF the Restore product is still the same, THEN the above results may be valid for our beloved Mercedes diesels. An increase in compression in our diesel engines can't really be a bad thing
