6.7L Maintenance Intervals

[hmdavid]

I have a 2012 F350 with the 6.7L diesel. The owners manual states that I should follow the directions from the Intelligent Oil-Life Monitor system for oil changes. I know my 2006 F350 with 6.0L required oil changes at 5000 mile intervals. Should I stay with the 5000 mile interval or follow the IOLM system? I want this diesel to last as long as my 6.0L did.

The jury is out on this one. Half the guys on here follow 5k intervals, and half use the IOLM.

More importantly is fuel filters and water separator!

I go with 4500 miles. Oil is cheap insurance

I'm doing 5k oil change and 10k fuel filter change.

Thanks for the input guys. I'll probably follow my old routine of oil changes at every 5000 miles with fuel filters at every 10000 miles. I drain the water separator at least once a month.
I understand Ford's thoughts behind the IOLM and it may serve some folks but my truck will be worked hard in the coming couple of years. I am currently deployed to Afghanistan but when I return, my truck and I will be clearing a lot for our retirement home. The truck will be hauling timber to a yard to be sold on a 36' trailer. Then it will be used to haul a backhoe to the property to dig out the basement. After that, it's hauling building material for a while.
When it's all said and done, she will be my horse and cattle hauler. Enjoying the site so far and look forward to further discussions of interest. Thanks again guys.

Filter in IOLM is what I have been doing.

Your IOLM will trip about every 7500 miles.

I did an oil analysis at that mileage and it was OK, So I've just stayed with the IOLM. Oil and filter approximately every 7500 and fuel and air filters every other oil change

I change my oil every 3,000 with the DPF EGR intact, 5,000 when it's deleted.

Changing at 3,000 miles is overkill. I'm sure you already know this, though.

Had my truck since Aug '12 and it only has 2500 miles on it. Going to be hauling my 36ft Fifth wheel, 200 miles tomorrow. Going to change the oil afterwards. Ive been getting the Notices in the mail from ford saying that my estimated mileage should be 10k by now. LOL
