Average engine hours for 100 000 miles

Most of you are missing the point. At least the trucks with DCI display gives you % of oil use left before an oil change is needed. Around 12% a you get a DCI display to change the oil soon. This is determined by mileage, fuel used, speed, temperatures and hours. Therefore, a reading of low milage and high hours may indicate a lot of idling and trigger the change oil soon warning before the recommended 7500 oil change interval.

Since the computer keeps track of the hours why not display it. A good GM mechanic maybe able to judge wear and tear on an engine by hours alone, but for the average owner, it really means little but as it was said earlier, high hours and low milage could be a red flag if you're buying a used truck.

I would use it to get an average number of hours per day. Get the purchased date, do the math and get the number of days old the truck is, then divide it by the hours. A high number of hours per day would indicate a lot of commuter driving, long haul driving or a daily work or delivery truck. You be the judge on how many hours per day would be good or bad for a used truck.

1. That’s a ton of hours!

2. Wow – that’s really low!

So, what’s the magic number? 1000 for gas engines? 2500 for diesel?

I was driving my 2017 pickup today with 21360 miles on it, and after a recent service, they exposed a digital dashboard that gave me my engine hours. I had a total of 627 hours on my truck, with 595 of it driving and 32 at idle.

627 hours! On a boat, that would be considered a decent number to most audiences.

I am going to average out the running hours of my engine to mileage for the sake of developing a chart and use the values of 22,000 miles to 600 hours of run time. This will “normalize” the numbers a bit for an apples to apples comparison.

Each vehicle will be different, but after research, this seems to be the average of most vehicles.

Let’s put this in context. If you were shopping for a car by modern standards, and you found a 15-year-old car with 50,000 miles on it, you’d say it’s hardly used. So why is a boat with gas motors given the flag of death with 1400 hours on her? In fact, it may actually be easier on the motors as we don’t tend to run our boats as hard or varied as we do our cars. Diesel engines even have more longevity as there is not the internal combustion components that will break things down as easily. I’ve seen diesel engines run for 1,000,000 miles – this would translate to 167,000 hours. This is a bit of an aberration for an example, but I think you get the point.

My recommendation is not place the Scarlet Letter of “high hours” and educate our boating community. It really comes to maintenance and age. (I could say that I have high hours on me, or at least it feels that way!) Look at age of the engines, maintenance records, and oil changes. Get a mechanical survey, and send out the oil samples. Look at the wear and care of those engines.

Enter the total engine hours into the calculator and adjust the miles per engine hour, if needed, to determine the miles of driving equivalent from engine hours.

Engine Hours to Miles Formula

The following equation is used to convert Engine Hours to Miles.

M = EH * 27.5

• Where M is the equivalent miles of driving
• EH is the number of hours of engine run time
• 27.5 is the equivalent wear, in miles, an engine would see from idling for one hour (this can be adjusted in the calculator)

What is the Engine Hours to Miles Conversion?

Definition:

The engine hours to miles conversion is done to calculate the equivalent mileage worth of wear and tear an engine would see for running a certain number of hours while idling.

How to Calculate Miles from Engine Hours?

Example Problem:

The following example outlines the steps and information needed to calculate miles from engine hours.

First, determine the number of hours the engine is running. In this example, the engine is running for 8 hours.
