Maintain Power with AMSOIL Diesel Oils
When you notice reduced performance in Navistar/International diesel engine equipped vehicles, AMSOIL diesel oils can help address the problem.
Navistar/International diesel engines with Hydraulic Electornic Unit Injectors (commonly referred to as the Powerstroke), used in Ford pickups, vans and school buses, sometimes suffer driveability problems due to oil foaming. Leaching or RTV silicone from the oil pan gasket into the oil causes the foaming. Foamy oil interferes with fuel injection, which reduces engine power.
The ASTM D 892 Foam Test, Sequences 2 and 4, are used to evaluate diesel oils on their foaming characteristics relevant to this engine. Recent testing performed by an independent lab shows the results in the table.
According to test results, AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (AME) and AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD) are clearly not prone to foaming or contributory to the foam-caused driveability problems of the IH engine.
The test also shows AME and HDD dissipate foam more quickly than Rotella T, a popular diesel oil often recommended by ford. Faster foam dissipation means reduced foam related driveability problems.
Let your customers know that silicone leaching diminishes with increased engine mileage, and in the meantime the solution to foam-induced driveability problems, regardless of oil brand in use, is an oil change.
