Summary
The base numbers of three different lubricating oil samples were determined. Work was carried out using different electrode systems in different solvent mixtures (glacial acetic acid/toluene and glacial acetic acid/chlorobenzene) and with different titration modes (drift and time-controlled dynamic titrations). The results obtained displayed no significant differences in their reproducibility and were all within the tolerance limits.
