Caterpillar. The difference counts.Recommended Use Cat earthmoving, commercial, marine and on-highway truck diesel engines* Low-emission diesel engines including Cat engines with ACERT Technology Heavy-duty diesel engines made by other manufacturers that recommend API

CH-4 or CG-4 classification oil (See Typical Characteristics on page 2 for more information)

Automotive gasoline engines that require API SJ classification oils* Excluding 3600, 3116 and 3126 MUI Marine and MaK diesel engines. The 3116 and 3126 MUI

Marine diesel engines with closed crankcase ventilation systems should use Cat SAEO.

Discover the DifferenceCat DEO is developed, tested and approved by Caterpillar to meet the same highstandards as Genuine Cat Parts.Factory-FillUsed as standard factory-fill for Cat machines.Increased Engine LifeResists oxidation and prevents build-up of deposits onpistons and rings.Longer IntervalsExtends oil drain intervals while providing excellent engineprotection and performance when used in conjunction with our SOSSM Services oilanalysis program.P roven PerformanceTested thoroughly in Cat diesel engines including Catengines with ACERT Technology to ensure excellent engine life and performance.Long-Lasting ProtectionImproved soot control and enhanced shear stabilityenable oil to maintain proper viscosity for longer operating periods in Cat engineswith ACERT Technology, especially those equipped with HEUI systems.

Cat DEO

Tested Beyond Industry StandardsIn addition to the tests required for the ECF-1classification, Cat DEO undergoes fourproprietary multi-cylinder endurance tests, avariety of quality assurance tests andthousands of hours of field service. Only whenit has passed all these tests can it beapproved by Caterpillar. The chart to the leftindicates the differences between ECF-1standards and the proprietary standards ofCaterpillar.
