Lubricating oils essential characteristics and maintenance
SAPS and lubricating oil quality
Kohler classifies synthetic lubricating oils among two main categories for SAPS level and three
subcategories for quality level.
SAPS stands for Sulfated Ash, Phosphorus, and Sulfur. Phosphorus and sulfur are often incor‐
porated as part of additives to increase oil performances (for example: anti-wear, anti-oxidiza‐
tion, cleanliness); sulfated ashes are the result of the combustion of the additives in a running
diesel engine. SAPS can quickly damage exhaust gas aftertreatment systems (EATS) if not
mastered properly. This is why the use of "low SAPS" lubricating oils is mandatory in diesel
engines equipped with exhaust gas aftertreatment systems.
Information
The use of mineral oils is strictly forbidden in Kohler KD diesel engines.
Kohler classifies synthetic lubricating engine oils in three categories for quality and two subca‐
tegories for SAPS content:
– Oil category 1: mineral oils
– Oil category 2: standard quality / synthetic multigrade oils
– Oil category 2.1: standard quality / synthetic multigrade oils dedicated for engines with
EATS (low SAPS engine oils)
– Oil category 3: high quality / synthetic multigrade oils
– Oil category 3.1: high quality / synthetic multigrade oils dedicated for engines with EATS
(low SAPS engine oils)
Information
Oil categories 2.1 and 3.1 must be used only with USLD fuels (wit a sulfur content lower than
15 ppm).
