What is the equation to convert engine hours to miles. I’ve read to conflicting stats. One says multiple hours x30, one says x60? Which is correct???

+1 50 would be extremely optimistic in these parts. 25 would be what I use here.
The yard shifter trucks I work on at UPS have an hour meter and an odometer. We do PM’s based on hours. I’ll look at one and report back what they do in an industrial setting.
This is a truck that moves trailers around a hub and doesn’t go in the road.
My wife’s 2021 Suburban has 51,xxx miles and 2,092 hours. Works out to 24mph in her case.
Edit-I just looked at the Yukon she had prior and it had 73,584 miles and 3,214 hours, 989 of those were idle hours. 23 mph overall.

What is interesting is I can pull up the number of engine starts on semi trucks. I don’t know if you can pull that info on say a Mustang GT as an example.
I have always been a fan of changing oil based on hours rather than miles. I think all cars should have hour meters.

GM, for their vehicles equates 1 hour to 33 miles. They have a paper about it. It comes up pretty often on the Caprice board as there are a ton cars there with 10,000 to 20,000 engine hours on them.
Your data will be very valuable and I can't think of a better example to compare hours vs miles as it relates to engine use and wear!

Miles / Hours varies greatly depending upon type of service the vehicle is in, the locations (city or suburbs or rural), etc ....
There is no OSFA answer to this.
Many newer cars have this info for you; they will track hours as well as miles. If your vehicle does not have this feature, you're going to have to do some timed trials and make an estimate for your specific situation.

It's good piece of information until it decides to randomly reset to 0.
My Prius calculates that for me.
I forgot to mention that I'm waiting delivery of a scangauge2. I plan to put that in my Sienna and possibly it calculates that or at least will give me the data points.
You would be better off approximating how many of your miles is highway driving and adjust the multiplication factor accordingly.
