The amount of leaking oil which remains in the used grease is diagnosed in comparison with the values for new grease. If too much oil is bled in comparison with new grease, the grease has become soft and "soupy", due to water, for example, or the thickening agent being destroyed by mixing.
If, by contrast, too little oil is bled, the grease is oxidised or "dried" by other factors, such as a lack of relubrication intervals or bleeding caused by significant oscillation strain. As such, this procedure is of particular interest, as it allows valid conclusions to be drawn in instances where many standardised tests cannot be performed due to a lack of used grease.
