ExxonMobil diesel engine oils meet Cat ECF-1 spec
ExxonMobil has announced that three of its diesel engine oils — Exxon XD-3, Exxon XD-3 Elite, and Mobil Delvac 1300 Super — all have met Caterpillar's ECF-1 (engine crankcase fluid) specification, a new standard developed to ensure optimum life and performance of Cat engines.
Created to help Cat engines meet 2002 emission regulations, lubricants meeting ECF-1 specs provide superior soot dispersion, wear control, and piston deposit control.
To meet ECF-1, lubricants must have API CI-4 or CH-4 certification, and pass a Cat 1P SCOTE test (ASTM D6681).
