Which Diesel Engine Oil is Right for You?

Which Diesel Engine Oil is Right for You?

1. American Petroleum Institute – API:

The API Engine Oil Licensing and Certification System provides a simple designation of letters and numbers that allows engine manufacturers and oil marketers to clearly provide users with the information they need to ensure that the proper oil is selected for an engine. Each letter/number designation identifies a service category (e.g., CI-4) which is linked to a series of tests that the oil must pass before it is allowed to carry that designation.

The below table outlines some API “C” series service categories and the general performance requirements that the diesel engine oil must meet.

Model Year:

1994

Intended for:

Off-road engines which use fuel containing more than 0.5% sulfur.

Provides control of:

  • Piston deposits.
  • Piston, ring and liner scuffing.
  • Wear and corrosion of copper containing bearings.

Model Year:

1994

Intended for:

2-stroke diesel engines.

Provides control of:

  • Piston deposits.
  • Piston, ring and liner scuffing.
  • Wear and corrosion of copper containing bearings.

Model Year:

1991

Intended for:

High speed4-strokeon-highway heavy-duty diesel engines meeting 1991 emission standards.

Provides control of:

  • Piston deposits.
  • Piston, ring and liner scuffing.
  • Wear and corrosion of copper containing bearings.
  • Oil consumption.
  • Ring and liner wear.
  • Oil thickening due to soot.

Model Year:

1995

Intended for:

High speed4-strokeon-highway heavy-duty diesel engines meeting 1991 emission standards.

Provides control of:

In addition to providing control of the parameters listed for CF-4 oils, the classification provides additional control of:

  • Oil filter plugging due to soot.
  • Oil thickening due to oxidation.
  • Valve train wear.
  • Foaming.

Model Year:

1998

Intended for:

High speed 4-stroke diesels engines meeting 1998 US EPA emission standards and using fuels with less than 0.5% sulfur.

Provides control of:

In addition to providing control of the parameters listed for CG-4 oils, the classification provides additional control of:

  • Viscosity loss due to shear.
  • Sludge.
  • Oil volatility.

Model Year:

2002

Intended for:

High speed 4-stroke diesel engines meeting 2004 US EPA on-highway emission standards implemented in 2002. Formulated to sustain engine durability where EGR is used. Intended for use with fuels having less than 0.5% sulfur.

Provides control of:

In addition to providing control of the parameters listed for CH-4 oils, the classification provides additional control of:

  • Low temperature pumpability.
  • Elastomer compatibility.
  • High-temperature/high-shear viscosity.

Model Year:

2004

Meets all requirements of CI-4 but includes increased resistance to oil thickening from soot and increased shear stability

Model Year:

2006

Intended for:

High speed 4-stroke diesel engines meeting 2007 US EPA on-highway emission standards.

Provides control of:

In addition to providing control of the parameters listed for CI-4 oils, the classification provides additional control of:

  • Sulfated ash, phosphorous and sulfur content

Model Year:

2017

Intended for:

High speed 4-stroke diesel engines meeting 2007 US EPA on-highway emission standards.

Provides control of:

In addition to providing control of the parameters listed for CJ-4 oils, the classification provides additional control of:

  • Engine oil aeration.
  • Engine oil oxidation.
  • Viscosity loss due to shear

Model Year:

2017

Intended for:

High speed 4-stroke diesel engines meeting 2017 US EPA on-highway emission standards.

Provides control of:

In addition to providing control of the parameters listed for CK-4 oils, the classification provides additional control of:

  • Enable fuel economy benefits.

2. European Automobile Manufacturers’ Association – ACEA:

The European Automobile Manufacturers’ Association – ACEA is an organization that represents the 15 most important European motor vehicle manufacturers. According to their statement, ACEA is an advocate for the automobile industry in Europe, representing manufacturers of passenger cars, vans, trucks and buses with production sites in the EU.

Among many other activities ACEA defines specifications for engine oils so called ACEA Oil Sequences. The sequences are usually updated every few years to include the latest developments in engine and lubricant technology.

ACEA itself does not approve the oils, they set the standards and oil manufacturer’s may make performance claims for their products if those satisfy the relevant requirements.

Stable, stay-in-grade oil providing excellent control of:

  • Piston cleanliness.
  • Wear.
  • Soot handling.
  • Lubricant stability.

It is recommended for highly-rated diesel engines:

  • Meeting Euro I, Euro II, Euro III, Euro IV and Euro V emission requirements.
  • Running under very severe conditions, e.g. significantly extended oil drain intervals.

It is suitable for engines:

  • Without particulate filters.
  • Some EGR engines.
  • Engine fitted with SCR Nox reduction systems.
