Godzilla Idle hours question
I have a new to me F250 - 2022 Lariat with 51300 miles, 1970 hours and 470 idle hours. Is this a lot of idle hours compared to total hours and mileage and should I be worried about cam issues going forward?

I don't think idle hours is/was the issue. My truck went south at 36K miles and idle hours are minimal.
Update: My truck has 65 idling hours on it at 55K miles. So, I don't think idling hours were the source of my lifter/cam failure.

Not being a smartazz to the OP but why buy a used 7.3 engine and think you might have to worry about a malfunctioning part that is a hit and miss problem. If it craps the bed deal with it, untill then don't stress and enjoy the truck.
Those aren't alot of idle hours seems normal to me. As a reference my '21' with 208,249 miles, 5,241 engine hours, idle hours 1,666. 😉

Unfortunately... Sometimes used is someone elses problem they sold to start over again. If you throughly went through the truck and started fresh with all maintenance oils and filters. Visually checking brake pads and lubing the slide pins. Maybe even doing plugs just because they're cheap and super easy to change out. That in my mind would put my mind at ease and would figure that in the price when buying it. 🤔

Seems higher than average but I wouldn’t be concerned.
My 2020 7.3 has 100k miles and coming up on 5400hrs of which 3000 are idle hours so I’m at 55% idle hours.

33 miles per hour x 1970 is 65k miles. So its a little on the high side but nothing to worry about at 26 miles per hour.
I would change the transmission fluid and antifreeze a little early. If you are worried, transmission fluid now as it could have been a city light to light or job site to job site dealy…

I wonder what constitutes idle hours. Sitting at a stoplight? Coasting up to a stoplight with RPM at 1K ? Low speed through a parking lot? My truck is never left idling. Yet, it has some hundred hours of idle time.

Maybe someone here can point to the source of some info I heard that the oil life algorithm counts idle hours differently than running hours; idle time decreasing oil life by something like a factor of 2X?

I have not seen that on my 7.3. It's running on a 10k mile clock. 1% = 1000 miles driving or idling.
