“Technology 4” Raised Questions about Phos Retention Measurement
Technology Type 4 convinced some members that the only way to get out ALL the volatile P was to use the EOT sample.
Unclear if Technology Type 4 is a viable GF-4 additive package – but it doesn’t matter.

4. Some have suggested it’s a losing battle to continue to push for the 20 hour PR calculation.
I don’t think so…
Because having a 100 hour limit to block oils with uncommon ZDDP systems doesn’t preclude having a 20 hour limit and a 100 hour limit
and to reliably correlate with the field, we need the 20 hour limit.

5. Effect of Phosphorous Volatility Phosphorous Exposure and Emissions Performance
A Little History

6. NYC Taxi Test Vehicles: 2003 Ford Crown Victoria with Ford 4.6 L V-8
Test Duration: 100,000 miles
Oil Change Interval: 5,000 miles
Service: moderate to high temperature urban driving
Two lubricants GF-4, 5W-20, 0.076% P:
Conventional ZDP
HPR™ ZDP

7. Conclusions
NYC Taxi Trial Conducted with % P, GF4 Fluids Demonstrated that High Phosphorous Retetion ZDP:
Keeps P in oil drains
Maintains excellent antiwear/antioxidancy performance in the field
Less P is deposited on the TWC resulting in statistically significant
Improved TWC THC light-off time
Lowered NOx emissions.
HPR™ ZDP clearly shows improvements in TWC efficiencies and protects engines in real world field service.

16. Summary and Recommendation
In addition to a 100 hour limit
Works as a backstop to prevent attempts to get around the PR requirement with potentially less effective anti-wear systems
Including a 20 hour limit
Greatly improves test discrimination between good and poor phos volatility oils
Correlates with peer reviewed field studies
Discriminates in the proper direction
Helps ensure catalyst protection
In addition – all the statisticians have reported that the 20 hours is preferred…
