My revelations after reading this thread from Bill:
- Hey Blue, check out this great oil article-really
- Synthetic refers to "properties" and not ingredients nor how it's made (same with semi-synthetic, i.e. "the big lie").
- The stock oil lasts the life of the engine; viscosity breaks down fast.
- "Synthetic oils made from pure PAOs or Diesters hold viscosity longer.
- Minimize viscosity spread by DIVISION (not subtraction)!
- Just because it says API SM doesn't mean it has been tested to be an API SM (I still need a better description of the visual-identification cues to understand how to reliably tell the difference)!
