I wasn't really sure where to put this.
I mean, a Crown Vic is a passenger car and the diesel fuel is acting as a lubricant, so maybe Passenger Car Motor Oil (PCMO) - Gasoline Vehicles? However, if it's using diesel fuel as engine oil, does that make it Heavy Duty engine Oil (HDEO) - Diesel Vehicles?
It is certainly engine oil related, so Off Topic is probably the worst place to put it, but whatever.
