Up here in Canada our ford dealers are really pushing for a max of 5k miles (8000 kms) and recommending synthetic at that... they are going as far to say that warranty may not be honoured if you follow Ford’s oil life monitor. This fear mongering from dealer reps is just nuts. They are scaring people to come in every 6 months minimum or you will lose your warranty (oh the horror). They are publicly saying on Facebook forums that all oil is worn out by 5k miles and must be changed. It can’t possibly last any longer. And following the oil life monitor will surely damage the engine.
Didn’t ford send a letter out to dealers telling them to stop this nonsense? Anyone have a link to it?
