  1. Phosphorus VolatilityChevron Oronite Perspective February 2007

  2. Phosphorus Volatility • Desired outcome: Identify an effective bench test method to measure P-Vol • We believe that PEI165 represents best available option • We have worked with Savant to evaluate PEI165 more fully • PEI 165 correlates with both field and IIIG data • PEI165 also ranks ZDP in line with chemical composition relating to volatility • Discrimination power greater than IIIG • ROBO should continue evaluation as alternative

  3. PEI165: Thermal Stability • PEI165 correctly ranked primary vs. secondary ZDP (thermal stability and volatility) Courtesy: Savant

  4. PEI165: ZDP Volatility • Created model ZDP compounds to generate controlled volatility • PEI165 correctly ranked against ZDP volatility repeats Less volatile

  5. PEI165: Field test correlation • Ranked corrected against Ford field test reference oils Courtesy: Savant

  6. PEI 165 vs. IIIG Hypothetical point TMC 435 TMC 434 Ford field test Using the trend line above: IIIG 84.4% = 50.1 mg/L PEI165 IIIG 82% = 58.6 mg/L PEI165

  7. PEI165: repeatability

  8. PEI165 Summary • Provides correct correlation with ZDP type, ZDP molecular weight, Ford field test and IIIG • Provides better separation than IIIG (~10% in IIIG vs. ~50 mg in PEI165) • Provides better test repeatability • Preserves IIIG parts • Cost effective versus IIIG Assuming no change in P chemical limit, Oronite supports PEI165 with appropriate P/F limit

  9. ROBO for P Retention • ROBO P retention correlates with IIIG reference oils (courtesy: Rohmax and GM) • TMC 434 80.3% • TMC 435 88.8% • TMC 438 81.% • Provides an 8.5% separation between 434 and 435

  10. ROBO for P Retention • ROBO repeatability is a concern • Two repeats (B) differ by 10% • A third (A) is different only in base stock • Will require more study or development
