Doplňujúce informácie
| Significance and Use | ||||||||||
|
5.1 Some fuel dilution of the engine oil may take place during normal operation. However, excessive fuel dilution is of concern in terms of possible performance problems. This method provides a means to determine the magnitude of the fuel dilution, providing the user with the ability to predict performance and to take appropriate action. |

| 1. Scope | ||||||||||
|
1.1 This test method covers the use of gas chromatography to determine the amount of diesel fuel in used engine lubricating oil. This test is limited to SAE 30 oil. The diesel fuel diluent is analyzed at concentrations up to 12 mass %. 1.2 This test method is limited to
gas chromatographs equipped with flame ionization detectors and
temperature programmable ovens.
1.3 There is some overlap of the
boiling ranges of diesel fuel and SAE 30 engine oils. Moreover, the
boiling range of SAE 30 oils from various sources can vary
appreciably. As a result, the calibration can be altered by as much
as 2 %, in terms of fuel dilution. When testing unknown or mixed
brands of used engine oil, it should be realized that the precision
of the method may be poorer than the precision obtained when
calibrating with a new oil representative of the used oil being
tested.
1.4 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. |
