Engine Hours?

[karnovking]

Can anyone tell me how engines which are measured in hours would be translated into miles?

Like what would be considered high hours on a motor and what is considered low hours?

hours as in.... time?
ive never heard the expression of high hours on a motor before.

I'm guessing an engine running at 2500 RPMs for one hour is equivalent to 60 miles. So 3334 hours is roughly about 200,000 miles. 1667 hours is about 100,000 miles. So, that should give you an idea right there.

If the engine runs at 3000 RPMs, then it would be about 70 miles in one hour.

These are just forumlas I'm making up. Most 4 cylinder cars run almost 2500 RPMs at 60 and 3000 at 70. So I'm using this as a reference. If your engine runs about 2500 RPMs, use "hours x 60." If it runs at 3000 RPMS, use "hours x 70." This may not be SUPER accurate, but will give you a rough idea.

well now, this depends on what gear the car is in.

Marine engines, contruction and agricultural vehicles almoat always have hour meters on them, that measure the length of time the engine actually runs.
This is because actual mileage on such vehicles is less useful than the hours the vehicle runs.

In cars, its the same way......100k miles of city driving puts many more hours of use on a car engine and much more wear, than 100 k of highway driving but we cannot tell. IMHO cars should track mileage AND hours on the negine.

In my experience,
2000 hours is equal to about 40 to 60 k miles on a car.

Its rare to find construction or agricultural vehicles with more than 8000 to 10,000 hours on them that are not completely worn out.

okay thanks. That was pretty simple, i'm shocked I didn't come up with that "formula" myself. Not exact, but a good way to ballpark it!!
