One value crops up again and again during oil monitoring:
The acid content, indicated as the neutralisation number (NZ) or acid number (AN).
Are acids in oil normal?
Why does the data sheet for my new oil also have an acid number?
Why can a base and an acid number be measured simultaneously in engine oil?
What is the ipH value?
These questions, which are commonplace for oil analysis specialists, quickly push the layman to his limits when evaluating oil analyses.
The answers to these questions are not as complicated as you might think.
We give them to you in our one-hour online training course.
