CASTROL® DURATEC™ ES 15W-40 TO MEET NEW CUMMINS CES 20092 SPEC IN JULY

ENGINEERING SOLUTIONS / Post date:
7 June 2019

Duratec ES 15W-40 is specifically formulated for modern natural gas engines with high-quality synthetic base oils that take performance to the next level – enabling drain intervals up to 1,200 hours.*
Although natural gas engines burn cleaner, they also burn hotter, making acid neutralization and oxidation and nitration control critical in protecting engines from deposits and wear over the useful life of the oil.

 

SUPPRESSES OXIDATION AND NITRATION

Higher combustion temperatures can lead to increased oxidation and nitrogen oxide formation. Duratec ES natural-gas engine oil suppresses and controls oxidation and nitration throughout extended drain intervals, preventing sludge, varnish, plugged filters, and deposits.

 

OUTSTANDING ACID NEUTRALIZATION

Acid formation can lead to corrosive wear. Duratec ES has outstanding combustion acid-neutralization capability throughout extended drain intervals, which helps to prevent corrosion and protects critical engine parts.

 

NEW CUMMINS CES 20092 SPEC IN JULY

In July, Castrol will be upgrading Duratec ES to meet the new Cummins CES 20092 spec. The new spec will provide significantly improved oxidation and thermal stability compared to previous versions.

  • Cummins will obsolete the current CES 20085 spec as of January 1, 2020
  • The new CES 20092 spec will be fully backwards compatible, so there will be no issues with mixing old and new Duratec ES products in bulk tanks and natural gas-fueled engines
  • There will be no changes to Castrol part numbers
  • As part of the transition, bulk, tote, and drum labels will be updated to feature the new CES 20092 spec
Castrol will provide additional customer communications closer to the launch of the upgraded Duratec ES. In the meantime, please reach out to your Castrol sales representative if you have any questions.
 
*Extending oil drain intervals should only be done in conjunction with a comprehensive used oil analysis program like Castrol Labcheck
