Oil Analysis - Scania PDE Operator's Manual

Oil analysis

To be able to extend the oil change intervals us-
ing an oil analysis, Scania LDF-2 and LDF-3 oils
must be used.
Oil companies can offer analysis of the engine
oil.
The following conditions must remain fulfilled
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)
• Soot (DIN 51452): < 3%
Such analysis measures the oil's TBN (Total
Base Number), TAN (Total Acid Number), fuel
dilution, water content, viscosity and the quanti-
ty of particles and soot 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
change intervals.
Checking oil level
Checking the oil level with the engine
switched off
Note:
Leave the engine off for at least 1 minute before
checking the oil level.
1.
Remove the oil dipstick (1) and check the oil
level. The correct level is between the mini-
mum and maximum marks on the oil dip-
stick.
2.
Top up with more oil (2) when the oil level is
at or below the lower mark.
Information on the correct oil type is found under
the heading Oil grade.
