For Gasoline Engine:
SN |
Introduced in October 2010 for 2011 and older vehicles, designed to
provide improved high temperature deposit protection for pistons, more
stringent sludge control and seal compatibility. API SN with Resource Conserving matches ILSAC
GF-5 by combining API SN performance with improved fuel economy, turbocharger
protection, emission control system compatibility and protection of engines
operating on ethanol-containing fuels up to E85. |
SM |
For all automotive engines currently in use. Introduced |
SL |
For 2004 and older automotive engines. |
SJ |
For 2001 and older automotive engines. |
SH |
For 1996 and older engines. Valid when preceded by current C
categories. |
SG |
For 1993 and older engines. |
SF |
For 1988 and older engines. |
SE |
Caution- Not suitable for use in gasoline- powered automotive engine
built after 1979. |
SD |
Caution- Not suitable for use in gasoline- powered automotive engine
built after 1971. Use in more modern engines may cause unsatisfactory
performance or equipment harm. |
SC |
CAUTION – Not suitable for use in gasoline- powered automotive engine
built after 1967. Use in more modern engines may cause unsatisfactory
performance or equipment harm. |
SA |
CAUTION- Contains no additives. Not suitable for use in gasoline- powered automotive
engine built after 1930. Use in modern engines may cause unsatisfactory
performance or equipment harm. |

For Diesel Engine:
CJ-4 |
Introduced in 2006 for high-speed four-stroke cycle diesel engines designed to meet 2010 model
year on-highway and Tier 4 nonroad 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 (o.o5% by weight). However,
the use of these oils with greater than 15 ppm (0.0015 by weight) sulfur fuel
may impact exhaust after treatment system durability and/or drain interval.
CJ-4 oils are especially effective at sustaining emission control system
durability where particulate filters and other advanced after treatment
systems are used. Optimum protection is provided for control of catalyst
poisoning, particulate filter blocking, engine wear, piston deposits, low and
high-temperature
stability, soot handling properties, oxidative thickening, foaming, and
viscosity loss due to shear. 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 |
Introduction 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 CG-4, and CH-4 oils may also
qualify for the CI-4 PLUS Designation. |
CH-4 |
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. |
CH-4 |
Introduced in 1995. For severe duty, high-speed, four-stroke engines
using fuel with less than 0.5% weight sulfur. CG-4 oils are required for
engines meeting 1994 emission stands. Can be used in place of CD, CE, and CF-4 oils. |
CF-4 |
Introduced in 1990. For high-speed, four-stroke, naturally aspirated
and turbocharged engines. Can be used in place of CD and CF oils. |
CF-2 |
Introduced in 1994. For severe duty, two-stroke cycle engines. Can be used in
place of CD-II oils. |
CF |
Introduced in 1994. For off-road, indirect injected and other diesel
engines including those using fuel with over 0.5% weight sulfur. Can be used
in place of CD oils. |
CE |
Introduced in 1985. For high-speed, four-stroke, naturally aspirated and turbocharged
engines. Can be used in place of CC and CD oils. |
CD-II |
Introduced in 1985. For two-stroke cycle engines. |
CD |
Introduced in 1955. For certain naturally aspirated and turbocharged
engines. |
CC |
CAUTION- Not suitable for use in diesel-powered engines built after 1990. |
CB |
CAUTION- Not suitable for use in diesel-powered engines built after
1961. |
CA |
CAUTION- Not suitable for use in diesel-powered engines built after
1959. |
