In February, 1995 the MTA was made aware of a product called MILITEC-1, which claimed to treat the metal surfaces inside an engine. This treatment results in reduced wear and increased engine life. The information included names and phone numbers of users and some oil analysis results. Several users were contacted and supported MILITEC's claims. Therefore the MTA conducted a small test.

The product is added to the oil as a method of application to the interior metal surfaces. It is not an oil additive. According to the supplier it affects the metal surface and reduces the rate of wear. This is measured by the wear metal levels in the oil analysis. As the treated surfaces wear the untreated metal is exposed and the level of metal wear increases. That is the time to redope the engines. This was estimated as every 15,000 miles.

Exact timing of the application is not necessary. If the treated surface wears away before reapplication the engine is as it is now, i.e. there is no negative result. If an engine is retreated a few thousand miles before needed there is a slight waste of material but no harm to the engine.

The annual cost is $22,400.00 as shown in attachment "B".This is less than the cost of two replacement engines. If 63% reduction in wear translated into 63% reduction in engine failures that would save 180 engines per year.In reality many engines are lost to causes other than gradual wear. If a six year life is assumed, 72 engines wear out each year. Accordingly 63% of 72 is 45 engines. Only 2 of these need to be saved by the use of MILITEC to recover the cost.

Recommendation:

The Quality Assurance Department recommends that MILITEC be used in the fleet system-wide. Also, test in other applications, such as facility air compressors and chillers.

MILITEC TEST
COST TO TREAT FLEET

The MTA will have 814 buses in revenue service as of February, 1997. The cost to treat the engines with MILITEC including the time to dispense and add the product will be $27.52 per bus for a cost of $22,400.00 annually.

Each engine will be treated with 2 ounces of MILITEC for every liter of engine displacement for an average of 22 ounces per bus or 140 gallons for the first fleet treatment. Every subsequent 15,000 miles each engine will be treated with 1 ounce of MILITEC for every liter of engine displacement for an average of 11 ounces per bus or 70 gallons for each fleet treatment. For the first 30,000 miles anticipated in the first year, the cost will be $18,900.00 for product plus the cost of labor at 206 hours per year adding $3,500.00 for a total of $22,400.00.
