I have a 2011 F550 6.7 with really low mileage. Only has 26500 kms on it. It sits in a heated garage most of the time. Gets used mainly in the summer to tow a telehandler or for camping duties. Oil is changed at the dealer using delvac 5w-40 synthetic. Oil was changed about 2.5 years ago. But it only has 5000 kms on the oil. What’s your opinion on changing oil on these? Around here people are crazy and say that you have to change oil every 8k kms max or 6 months. And that’s pushing it. They would rather you change every 5k kms. And fuel filters every 10k kms...
The truck has an oil life monitor but it has never gone off saying to change the oil. It’s out of warranty not based on time alone. It’s one of those things - it’s a tool. When I need it I need it to work. Just looking for opinions on these so I can learn more about it. It will likely be used more in the coming year then in the past.
