Application:  As an additive package to motor oil and fuel in 1,800 Horse Power diesel engine driving 1000 KVA CUMMINS electrical generator:  anti-wear protection and reduction in fuel and oil consumption during normal operation.

User: Overseas Quarry


This 1000 KVA Cummins Generator driven by 1,800 horse power engine was in service for more than 30,000 hours. According to the manufacturer’s instructions, oil and oil-filters had to be replaced every 250 hours. We started using Polytron after the generator was in service for about 5,000 hours. Within very short time of using Polytron MTC and Fuel Conditioner, we experienced an average of 10% reduction in fuel consumption. Based on used oil analysis (see tables in the following pages) we decided to extend the oil change intervals to every 1,000 hours and then to every 1,500 hours. Typically, this type of engine is overhauled after 17,000 hours in operation.

 In this specific case the engine was taken apart after 30,000 hours not because it had to be overhauled but because of penetration of water into its oil system. In spite of the water, there was no indication whatsoever that the engine  was deteriorating in performance. Nevertheless, after 100 hours in operation with water presence in the oil system, the general manager of the quarry decided to take the engine apart. “I have seen too many times what presence of water in the oil system can do to an engine, I don’t want to stretch my luck” was his answer when Polytron distributor told him not to worry. The general manager of the quarry  was very impressed  when he was told by the head mechanic in the repair shop that the engine parts looked like new and that he thought that there must had been a mistake in the paperwork, because the condition of the engine parts didn’t have any indication whatsoever that the engine was in operation for 30,000 hours or water penetrated the oil system. The Quarry manager was so impressed by the findings that he decided to invite the local distributor and the US manufacturer to produce a video-tape of the engine parts to use as a reference with his high recommendation for Polytron products. The engine was put together without replacing or machining any parts. According to our most conservative estimate, over 30,000 hours that the generator was in operation, the user saved at least $150,000 on repairs, fuel and oil consumption. And spent only $7,690 on Polytron products, a return of approximately $20 on each dollar invested in Polytron .

  The following pictures demonstrate the outstanding performance of Polytron products.


All the liners were micro-measured. There was no wear whatsoever, all the dimensions were within the manufacture’s specs of a new engine.


In all the liners you could see distinct traces of the cross-honing pattern of the original bore (pink arrow), and the liner  surfaces looked “polished”  like and shiny.
