Makes You Think...
This information came from a service bulletin written by
an OEM in the mid ‘70’s. Although there are many factors
that play into the life expectancy of an engine, such as
maintenance and care, the time factors and comparisons
made in the bulletin make you think.
An engine that runs at 1800 RPM for one hour is equivalent
to a car run at 40 miles per hour for one hour.
An engine that runs at 3600 RPM for 1 hour at twice the
RPM is the equivalent to a car run at 80 miles per hour for 1
hour.

precision it needs, but the numbers may open the eyes of
a customer who does not give the equipment the required
care it deserves.
A generator that operates under load for 100 hours is
equivalent to 8,000 miles on a car. This equates to only
running the engine for 2 hours per week over one year’s

per week for 52 weeks (depending on the load) would be
the same as putting between 62,400 to 124,000 miles a
year on a car.
What would the maintenance requirements be, versus what
they actually receive? Makes you think.
