I had a old 7.3 f-250. Ford I bought in 2010 with some damage to the front. Just got around to fixing it this year. We'll after sitting for 6+ years I changed oil and new batteries. Fired up after about 30 seconds of cranking and runs well. The only thing I did before storage was add anti-fungicide to the fuel. I thought that was doing good for sitting for so long.

Hi. As a suggestion, may want to run for 500 miles, and then install Oil System cleaner, and repeat oil change a second time.

^^^^^ I agree with above. Change the oil a couple of times in the first thousand miles. I restore vintage motorcycles that have set for years. You will be surprised at how much sludge that builds up in a motor that has set over time.

Doing better than me. Trying to get my idi 7.3 going after sitting for 6 months......grrrrrrr.Marty

I will watch for any contamination and change. I will change transmission fluid in the 6 speed because I don't know if the shop used synthetic fluid and I want to flush it anyway.
