  1. Using the Seq. IIIG to Reliably Provide Catalyst Protection Presented March 20, 2008

  2. The decision to use the EOT Sample for Phos Retention was taken at the last meeting – 1/8/08 EOT 40-hr 20-hr

  3. 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. “Technology 4” Raised Questions about IIIG@20 Phos Retention Measurement Infineum ESCIT 2007 Aug 9th_Version 3.pdf

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

  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 0.076 % 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.

  10. Case Study: Seq IIIG Phos Retention20 Hours and 100 Hours

  11. LZ Field Trial Oils 20 Hr IIIG 100 HR IIIG 90 85 Least Square Mean Phos 80 Retention 75 70 65 (Ford NYC Trial) HPR™ZDP (Ford NYC Trial) CZDP Sequence IIIG Results on LZ Field Trial Oils Demonstrates Good Separation at 20 and 100 hours

  12. Calculation of Phos Retention on Reference Oils • IIIG Reference Oil Data • 121 Submitted Results by Labs A, D, F, G • Three Reference Oils • TMC 434, SAE 5W-30, ~0.08 P • TMC 435, SAE 5W-20, ~0.08 P • TMC 438, SAE 5W-20, ~0.10 P

  13. Sequence IIIG Phos Volatility Data Clear separation of MEANS for ref data

  14. 35% of tmc-434 Runs! (99) (51) (48) (49) (# of Test Runs)

  15. Only 2% of tmc-434 Runs (99) (51) (48) (49) (# of Test Runs)

  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 IIIG @ 20 hours is preferred…
