CAFE blah , blah , blah !! While at my Hyundai dealer I over heard a customer complain that on his "new" 2012 Hyundai (DFI) that he needed a complete upper intake cleaning to the tune of $300 . The customer became irate when the service representative said that it is not uncommon for the Hyundai DFI engines to require a upper intake cleaning approx. every 30K miles ! Really ? ... That combined with a OCI of every 4,000 miles makes DFI engines a bit on the expensive side to maintain with normal performance . A new Ford Fusion with a traditional PFI engine remains on my short list of new vehicles to consider ...I don't want to be a "lab rat" experiment for auto makers and their marginally performing DFI engines !!
