MIL-PRF-9000 §4.6.3 - Compatibility of Lubricating Oils

We perform lubricants testing by specification MIL-PRF-9000, which includes testing the compatibility of lubricating oil with SAE 40 or 15W40 Grade oil. The lubricating oil sample is mixed with a given reference oil that is known to be SAE 40 Grade or 15W40 Grade in five different test tubes and in five different proportions. The mixed lubricating oil is shaken for fifteen minutes, either manually or in an automated vibrator. All of the test tubes are then placed in an oven and heated at 60C for up to two weeks. The samples are examined every two days for evidence of separation, such as sediment or haze in the oil. The test continues until evidence of separation is found or until the two weeks is up, whichever occurs first. This test is a section of MIL-PRF-9000 - Engine Lubricating Oil Specification.

We also perform compatibility testing by ASTM D7752FTM 3403MIL-G-81322 §4.5.3MIL-PRF-46170 §4.5.2MIL-PRF-83282 §4.4.3MIL-PRF-87252 §4.5.4, and MIL-PRF-87257 §4.4.3. These different test methods use different instruments or procedures or are used for certain sample types.
