I used to do UOAs for my TDIs before they both got destroyed in wrecks (not my fault)

I'm a little suspicious at the LOWER levels of metals present in the ELF. This would tell ME that the oil is not suspending as MUCH debris as the M1, in other words, leaving it to cling to the internals as opposed to absorbing it - which is what a good oil does.

I'd like to see this test vs. Delvac 1
