LUBRICANTS TOTAL recommended oils
S.A.E. Norms Table for selection of engine oil gradeSelection of engine oil grades recommended for climatic conditions in corntries of distribution.Evolution of the norms as at 01/01/2003
ACEA 2003 norms
The meaning of the first landter has not changed, it still corresponds
to the type of engine:
A:petrol and dual fuel petrol / LPG engines.B: dieselengines.
The figure following the first landter corresponds to the type of oil:
3:high performance oils.4:oils specifically for direct injection diesel engines.5:very high performance oils permitting lower fuel consumption.Example:
ACEA A3:high performance oils specifically for petrol and dual fuel
petrol / LPG engines.
ACEA A/B:blended oils giving very high performance for all engines,
also permitting bandter fuel economy, specifically for direct injection dieselengines
NOTE:From 01/01/2003there is no longer any reference to the year
of creation of the norm (example:ACEA A3/B3 98becomes ACEAA3/B3).
API norms
The meaning of the first landter has not changed, it still corresponds to
the type of engine:
S: petrol and dual fuel petrol / LPGengines.C: dieselengines.
The second landter corresponds to the degree of evolution of the oil
(ascending order).
Example:Norm SLis more severe than norm SJ, corresponding to a
higher level of performance.
