Oil analysis
To be able to extend the oil change intervals us-
ing an oil analysis, Scania LDF-4 oils must be
used. Certain laboratories offer engine oil analy-
sis.
The following requirements must remain satis-
fied when the oil is changed:
• Viscosity at 100°C (212°F): max. ±20% of
original value of the fresh oil.
• TBN (in accordance with ASTM D4739): >
3.5.
• TBN (in accordance with ASTM D4739): >
TAN (in accordance with ASTM D664).
• Oil oxidation (in accordance with
DIN 51453) > 10.
Such analysis measures the oil’s total base num-
ber, TBN (Total Base Number), total acidic
number, TAN (Total Acid Number), fuel dilu-
tion, water content, viscosity and the quantity of
particles in the oil.
The result of a series of analyses is used as the
basis for establishing a suitable oil change inter-
val.
If the conditions are changed, a new oil analysis
programme must be carried out to establish new
oil change intervals. Work out the new oil
change interval for the engine in conjunction
with the workshop.
REQUIREMENT!
Only Scania LDF-4 oils may be used in conjunc-
tion with oil analysis and a possible extended oil
change interval.
Depending on the market, the warranty condi-
tions may also change if the oil change intervals
differ from the recommended Scania timetable.
