This bus company was looking for ways to lower their engine oil operational costs as well as reduce their buses’ environmental impact. As Triple R previously used their expertise to help the company resolve contamination issues with their injection pumps and nozzles at their diesel fuel station they turned to us again.

Dirty engine oil can cause a multitude of problems;

  • Wear and tear
  • Loss of power and efficiency
  • Increased emissions
  • Higher operating costs

The company was spending $106,920.00 per year just in oil changes for their fleet

They had seen the results of Triple R’s oil cleaning solutions, they trusted our expertise to lower their operating costs.


The bus company was changing their oil at 9320 mile intervals approximately 6 times per year (55,923 miles) costing them $1,620.00 per year. This was being done across 66 buses. Triple R’s goal was to significantly reduce the frequency of the oil changes by using our innovative AL-100 housing outfitted on the engine, combined with D-series elements.

The oil cleaning system allows for ease of install and element changes. The inlet was teed into the pressure line of the engine and the return was gravity fed back to the oil pan.

  • D-Series elements
