AMSOIL has a full line of products, including outstanding air, oil, fuel, hydraulic and coolant filters from Donaldson Filters, geared for both light and heavy diesel applications.

AMSOIL’s diesel products are perhaps one of the most exciting areas of the AMSOIL product line.

One of AMSOIL’s most exciting new products is the new DEO Diesel Oil for the new generation of diesel engines requiring API CJ-4 emission quality oil standards. Click here to find out more!

AMSOIL Diesel Concentrate (ADF) is a total system cleaner and lubricity improver for all types of diesel engines.  It provides maximum diesel operating efficiency and compensates for the variances in quality of different fuels, including biodiesel, and the deficiencies of today’s Ultra Low Sulfur Diesel (ULSD) fuel for better engine operation.  AMSOIL Diesel Concentrate (ADF) meets the low sulfur mandate.  It improves diesel fuel quality to exceed today’s stringent performance requirements.  AMSOIL Diesel Concentrate (ADF) extends equipment life, lowers operating costs and improves diesel performance.

I’ll post more later, but for now, check out these two pages to see examples of the benefits received by those who choose AMSOIL for their diesel applications.
