Hey, I have a 2010 F-350 with the 6.4L PowerStroke Diesel and I am planning to go to Baja 1000. My dealer keeps telling horror stories like, "just 1 tank of Pemex diesel and your motor is junk" and saying that the warranty voided immediately. Surely, you can't tell me that everyone who has driven their new Ford in Mexico has a blown engine now !! Can anyone enlighten me or give me a better idea than carrying 150 gallons of fuel around with me ??
