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.
