Caterpillar ECF-2 Test Summary

• 1. Oil Consumption Control –variable
• 2. Discrimination - No Parameter distinctive
• 3. No Correlation – Oil consumption with deposits

– Oil consumption with 2nd ring stick

• 4. Propose Continue C13 test for PC-10
• 4. No Passing oil found – Ref # 4 best candidate
• 5. Failing Ref #1 oil is marginal
