MCVVolatility (Evaporation) (ASTM D-5800) SAE 50 Results

1. Higher temperatures produce greater volatility (evaporation).
2. Increased volatility causes increased oil consumption and emissions.
3. Oil is first heated to 250° C for a period of 60 minutes.
4. Air is drawn through the container holding the oil sample to remove vapor.
5. After 60 minutes, the remaining oil volume is weighed.

6. Comparison to initial oil weight.
7. A lower weight loss score indicates better performance.
