- Val, you have finally forced me to ask something I been thinking about
- for years. Maybe someone knows:
-
- 1. Is there any tests that a "saturday mechanic" can do at home?
-
- For additive depletion (there's so many)? You would have to test a
- new batch before you used it to establish a base line. What about
- contamination by metal wear or combustion by products? Viscosity is
- easy if you have the ASTM specs handy. I wonder what the guidelines
- for maximum levels are?
-
- 2. What "low end" cheap equipment do oil analysis companies use.
-
- Just some of my random thoughts.
