ENGINE OIL

API classifications of engine oil

The American Petroleum Institute classifies
engine oils according to their performance
(quality). Each category is given two letters.
The first letter indicates the field of
application.
S= Service, API categories valid primarily
for gasoline engines.
C= Commercial, API categories valid
primarily for diesel engines.
The second letter indicates the quality in
ascending alphabetical order.
API-SG=Oil for gasoline engine
API-CD=Oil for diesel engine
A higher quality than specified may
always be used.
Oils which fall into both classifications are
designated accordingly e.g. API SG/CC.
Further specifications from the motor
industry may also be found on the oil
cans

CCMC classifications of engine oil

CCMC stands for ComitÈ des Construc-
teurs d'automobiles du MarchÈ Commun
(Committee of Automobile Manufacturers
in the European Community).
The CCMC system is based on the API
classifications but takes into account the
special lubrication requirements of the
engines of European vehicles.
Engine
The viscosity should be selected according to outside
temperature. Do not switch to a different viscosity in the
event of brief temperature fluctuations.
