Maintenance
Lubricants and operating fluids
Excessive viscosity can result in starting difficulties. If the viscosity is too low, this can compromise
the lubricating efficiency.
Difficulty factors
Difficulty factors can be:
– Frequent cold starts
– Environmental influences
Operating temperature
•
• Dust
• High humidity
• Long standstill times
If there are difficulty factors or difficult usage conditions, the oil change and filter change must:
– be performed according to oil change interval
– be validated by oil analysis
Oil change interval
The basic change interval is defined in the maintenance tables. The change intervals are defined
as follows:
Basic oil change interval * Factor oil category * Factor sulfur content = change interval
Lubricant oil category
Factor oil category
Factor oil category
Lubricant oil category 3 and 3.1 "2" => double the maintenance schedule interval
Tab. 33: Oil category factor definition
Sulfur content in %
0 < sulfur content ≤ 0.5
0.5 < sulfur content ≤ 1 limited to lubricant category
2 and 3
1 < sulfur content ≤ 1.5 limited to lubricant category
2 and 3
Tab. 34: Sulfur content factor definition
Information
The use of sulfur in the ratio of more than 1% requires an additional approval from the engine
manufacturer to ensure that all the engine options, lube oil selected and maintenance schedule are
compliant with this very high sulphur rate.
Specific lube oil must be used => TBN is > 12 mgKOH/g
Engine oil operating monitoring
Take and analyze oil samples at least once per year and during each oil change and under certain
conditions.
Depending on application and the engine's operating conditions, sampling / analyses should take
place more frequently.

Factor oil category
"1/4" => reduce by 4 times the maintenance schedule interval
"1" => no change on the maintenance schedule interval

Factor sulfur content
1=> no change on the maintenance
schedule interval
1/2=> reduces the maintenance interval by
one half
1/4=> reduces the maintenance schedule
interval by one quarter.
