Demonstrations and Tests

Extended Drain Demonstration: Over-the-Road Fleet

Using AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil, AMSOIL By-Pass Oil Filters and used oil analysis, an over-the-road flatbed fleet extended vehicle drain intervals to 79,000+ miles, and realized a 29 percent reduction in the costs of oil-related materials and labor.

Used oil analysis confirmed the high quality protection afforded by the AMSOIL products. Wear metal, soot and acid levels remained low throughout the demonstration, while TBN remained high and viscosity midrange.

Extended Drain Demonstration: Grocery Warehouse Fleet

Using AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil, AMSOIL By-Pass Oil Filters and used oil analysis, a grocery warehouse fleet extended its oil drain intervals to 74,000+ miles and realized a 22 percent decrease in the costs of oil-related materials and labor.

Used oil analysis confirmed the superior protection afforded by the AMSOIL products. Wear metal, soot and acid values remained low throughout the demonstration, while TBN remained high and viscosity midrange. Note the significant viscosity loss suffered by the conventional control oil. Viscosity loss often leads to excessive wear.

325,350-Mile Drain Interval

Virginia independent owner-operator John Blevins used AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil, AMSOIL By-Pass Oil Filters and used oil analysis for a single 325,350-mile oil drain interval in the Cummins 350 engine of his 1984 Volvo White truck. Each oil analysis report showed excellent TBN retention and acid control. Each also showed excellent viscosity retention, soot control and wear control. Wear was measured by spectrochemical analysis of wear metals content. Spectrochemical analysis also showed excellent values for detergent-alkalinity and anti-wear compounds, further confirming the oil’s ongoing serviceability. Blevins’ extended drain demonstration ended three years after he installed AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil when he sold the truck. The buyer, a mechanic, has continued Blevins’ oil and filter regimen, using AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil and AMSOIL By-Pass Oil Filters. In fact, he did not replace the oil Blevins had installed in the engine three years previously. Today, the same fill of oil is in the engine and has seen 500,000 miles of service.

The valve cover and valve train in Blevins’ truck are still clean after 325,350 miles on one fill of AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil.
