Dear Andy:

This is to advise you of the treatment of one our wireline vehicles with GENESIS on December 1, 1995.

The vehicle was a 1978 Chevrolet with a Detroit 671 Diesel engine. The engine had over 500,000 miles of usage. One quart of GENESIS was used in the engine while running.

The results were visible within 15 minutes when the smoke coming from the exhaust, which was black, turned to a bluish color. The truck was then driven for about 50 miles. The truck ran with more power and an increase in horsepower which showed up in pickup. The engine ran quieter and smoother.

The oil and filter were changed and there was another decrease in the noise level. Then engine sounds just as good as new. We have not kept accurate mileage on the vehicle because there is a lot idling time, but it does appear that we are going much longer between fillups.

We intend to place GENESIS in our other vehicles.

Very truly yours,

R. Salinas
