Performance, Features & Benefits
Multigrade benefits
Compared to monograde oils, Shell Rimula R2 Extra can deliver the user a range of benefits associated with the use of multigrade oils. These include reduction of oil consumption by up to 30%*, longer oil life and improved fuel economy. (* As stated by a leading engine maker).
Protection for turbo-charged engines
Unlike some lower cost multigrade oils, Shell Rimula R2 Extra can be confidently used in many turbo-charged engines to provide protection and long engine life.
Piston cleanliness
Shell Rimula R2 Extra exceeds the normal standards of piston cleanliness associated with API CF-4 oils - the use of modern formulation chemistry delivers piston cleanliness that meets the standards of Mercedes Benz 228.1, guaranteeing the user consistently high performance in a range of applications.
Major engine manufacturer acceptance
Shell Rimula R2 Extra meets the recommendation of many major automotive engine builders in Europe and America, providing flexibility to vehicle and equipment owners.
Main Applications
Automotive diesel engines Shell Rimula R2 Extra is the ideal choice for a wide range of turbo-charged and non-turbocharged engines under normal operation. It is particularly recommended for use in older Mercedes-Benz trucks and buses as well as for cost effective lubrication in off highway applications such as agricultural tractors.
For more severe operations or applications in modern low emission engines we recommend Shell Rimula R3 or Shell Rimula R4 multigrade engine oils.

Health, Safety & Environment Health and Safety
Shell Rimula R2 Extra 20W-50 is unlikely to present any significant health or safety hazard when properly used in the recommended application and good standards of personal hygiene are maintained. Avoid contact with skin. Use impervious gloves with used oil. After skin contact, wash immediately with soap and water. Protect the Environment Take used oil to an authorised collection point. Do not discharge into drains, soil or water.

| CK-4 |
Current |
API Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017
model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel
engines. These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm
(0.05% by weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact
exhaust aftertreatment system durability and/or oil drain interval. These oils are especially effective at sustaining emission
control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils
are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as
protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and
high-temperature properties, and soot-related viscosity increase. API CK-4 oils exceed the performance criteria of API
CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories.
When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations. |
| CJ-4 |
Current |
For high-speed four-stroke cycle diesel engines designed to meet 2010 model year on-highway and Tier 4 non-road
exhaust emission standards as well as for previous model year diesel engines. These oils are formulated for use in all
applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, the use of these oils
with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or
drain interval. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and
can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm
sulfur fuel, consult the engine manufacturer for service interval. |
| CI-4 |
Current |
Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards implemented
in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are
intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4,
CG-4, and CH-4 oils. Some CI-4 oils may also qualify for the CI-4 PLUS designation. |
| CH-4 |
Current |
Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards. CH-4 oils
are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place
of CD, CE, CF-4, and CG-4 oils. |

| CF-2 |
Obsolete |
CAUTION: Not suitable for use in most diesel-powered automotive engines built after 2009. Two-stroke cycle engines
may have different lubrication requirements than four-stroke engines, so the manufacturer should be
contacted for current lubrication recommendations. |

Obsolete |
CAUTION: Not suitable for use in most diesel-powered automotive engines built after 2009. Later “C” category oils
are usually suitable or preferred for diesel automotive engines for which “CF” oils were specified. Older
equipment and/or two-stroke diesel engines, especially those calling for monograde products, may
however require “CF” category oil. |
