Maintenance questions
So my one specific question is in regards to the coolant. I read that an anti-foaming agent needs to be added every so often I guess, however any mechanic I ask has no clue wtf I am talking about. Anyone?
And besides oil and maintaining fluids, are there other special DIESEL maintenance habits I should get into?
Oh, and I have someone who has the same truck, with the 7.3. I did what he said for the oil and put Full synthetic 5-40 in. He told me since I don't do much heavy hauling I can get away with once a year on the oil changes. Anyone agree or not? It seems a little too good to be true, but at 15 quarts I hope it is.

Use 15W-40 Motorcraft or Rotella. Only Motorcraft filters. Change every 7500 or so miles. Change your fuel filters every other oil change every 15K miles or so. You can run Diesel Kleen every once and a while, but you shouldn't need it.
