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

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

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

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.

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

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

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.

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

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…
