Hello:
Here are two VOAs of Liqui Moly Leichtlauf HT 5W-40. These were from different batches of oil. Notice I had 40C and 100C, plus TBN tested. See VI in comment sections.
The elemental analysis seems to be more different than I would have expected. Do you think the results are because of production variations in the oil, ongoing oil blending changes, sampling error/precision by Blackstone, or combination of some or all?
