2011 F-350 Engine light on
#3
Thanks for your response. What I've been told is that these motors are designed for heavy work load and since I've retired I just drive to town etc. I was told that they need higher octane than what is supplied in my diesel fuel so I should add an additive. Not sure if its making any difference. The engine light only comes on when I've been highway driving for an hour or so and remains on until I get back to driving around town . Not sure what this means
