Full Description

1.1This test method evaluates an engine oil's resistance to aeration in automotive diesel engine service. It is commonly referred to as the Caterpillar-C13 Engine-Oil Aeration Test (COAT). The test is conducted under high-engine-speed (1800r/min), zero-load conditions using a specified Caterpillar 320kW, direct-injection, turbocharged, after-cooled, six-cylinder diesel engine designed for heavy-duty, on-highway truck use. This test method was developed as a replacement for Test Method D6894.

Note 1:Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1Exception-Where there is no direct SI equivalent, for example, screw threads, national pipe threads/diameters, and tubing size.

1.3This test method is arranged as follows:
