The objective of this work is to develop a bench-scale test capable of evaluating ground vehicle engine and gear lubricant performance in the area of oil deposition. The test should be capable of providing initial screening for candidate military specification lubricants, oil base stocks, and re-refined oils and should correlate with full-scale engine tests. The following conclusions may be drawn from this work: (1) the Army Fuels and Lubricants Research Laboratory-developed LUBTOT, thermal oxidation lube oil tester appears to be an effective test device for evaluating lubricants regarding oil deposits that are formed under a set of controlled test conditions. The tester has several distinct advantages, namely: ease of controlling test variables, small oil sample required, ease of cleaning between tests, simple unbias deposit rating method, and low cost per test; (2) the test method developed thus far does correlate with some of the Caterpillar single-cylinder reference tests. However, the method does not correlate with the 1-D, 1-H, and 1-H2 test results performed on selected REO oils; (3) the LUBTOT appears to be capable of differentiating between different re-refined base stock, which can be important in identifying base stock consistency; and (4) the LUBTOT can determine the effectiveness of the additive package in formulated oils regarding oil deposits caused by high-temperature operation.
