CASE
STUDY EQUIPMENT:
City
Bus Fleet PROLONG
PRODUCT USED: Engine Treatment Summary Municipal Rapid Transit system is running 29 buses
aged 1 yr. to 20 yrs. Careful
records had been kept on this equipment, and engine oil had been analyzed at
every oil change for wear metals. Oil
and filters were changed every 3700 miles. In each bus engine, 2 quarts of Prolong Engine
Treatment was added to 23 quarts of customer's regular motor oil, providing
approximate 8% blend. Results After monitoring the wear metals for about 6 months,
the service interval was extended conservatively to 6200 miles. First year savings in oil and filters were $22,000.
It is note-worthy that only the engines were treated.
Further savings should be realized when these buses have their
differentials treated with Prolong Anti-Friction Metal Treatment and the fuel
treated with Prolong Fuel Conditioner. These
will result in reduced fuel consumption. Also, savings beyond the $22,000 should be realized
in terms of extended life of the equipment, including fewer breakdowns, less
downtime, and fewer parts.
