A DVA NCE D ACID NEU T R A L I Z AT ION FOR E X T R E ME E X T E NDE D DR A IN Castrol Duratec ES 15W‑40 has outstanding combustion acid neutralization capability throughout extended drain intervals, preventing damage to engine surfaces from corrosive wear. E XCE P T ION A L PE R FOR M A NCE AG A IN S T OX IDAT ION A ND NI T R AT ION Natural gas engines have higher combustion temperatures than their diesel counterparts, which leads to increased oxidation and nitrogen oxide formation. Vecton NG 15W‑40 suppresses and controls oxidation and nitration throughout extended drain intervals, preventing sludge, varnish, plugged filters, and deposits.
