5.12.3 Approved engine oils and engine oil additives

Engine oils essential characteristics and maintenance
SAPS and engine oil quality
Kohler classifies synthetic engine 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 engine oil performances (for example: anti-wear, anti-
oxidization, 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" engine oils is mandatory in diesel
engines equipped with exhaust gas aftertreatment systems.
Information
The use of mineral engine oils is strictly forbidden in Kohler KD diesel engines.
Kohler classifies synthetic engine oils in three categories for quality and two subcategories for
SAPS content:
– Engine oil category 1: mineral engine oils
– Engine oil category 2: standard quality / synthetic multigrade engine oils
– Engine oil category 2.1: standard quality / synthetic multigrade engine oils dedicated for
engines with EATS (low SAPS engine oils)
– Engine oil category 3: high quality / synthetic multigrade engine oils
– Engine oil category 3.1: high quality / synthetic multigrade engine oils dedicated for engines
with EATS (low SAPS engine oils)
Information
Engine oil categories 2.1 and 3.1 must be used only with USLD fuels (with a sulfur content
lower than 15 ppm).
