I currently drive a 2009 Ford Fusion with a 3.0L v6 for my company car. I was planning on buying it for the wife when they present me with the offer, sometime around 120K miles (I drive about 7K miles a month, so it shouldn't be too long). I have to take it to be serviced by fleet vendors (Jiffy Lube, Valvoline, Midas, etc.) at 6K intervals. Is that too long of an OCI for 90% highway miles on conventional oil?
