Information
u The use of sulfur in the ratio of more than 1% requires an additional approval of the engine
manufacturer.
u Special lubrication oil must be used => TBN > 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.
From the indicated test methods and limit values, it emerges when the result of a single oil sample
analysis is to be viewed as abnormal.
Kohler Co. recommends to perform lube oil analysis of used engine lube oil for the following
parameters (minimum list).
– Viscosity
– Flashpoint
– Soot
– TBN
– Water
– Oxidation
– Ethylene glycol
– Wear elements (Iron, Chromium, Tin, Aluminium, Nickel, Copper, Lead and Molybdenum)
– Contaminants (Silicon, Potassium, Sodium, Lithium, Antimony, Silver, Titanium, Vanadium,
etc...)
– Additives (Calcium, Magnesium, Boron, Zinc, Phosphorus, Barium, Sulfur)
– Diesel fuel rate (dilution)
Engine oil analysis
Analyze oil at regular intervals.
