In 2015, we expanded our European Car Formula line to include a Full-SAPS (Sulfated-Ash, Phosphorus and Sulfur) SAE 0W-40 multi-viscosity.
Featuring the same premium synthetic formulation and recommended for the same specifications as European Car Formula 5W-40 "Full-SAPS" Synthetic Motor Oil, European Car Formula 0W-40 "Full-SAPS" Synthetic Motor Oil provides European vehicle customers with a different viscosity option.
What does "SAPS" mean?
European cars' emissions systems and after-treatment devices, such as Diesel Particulate Filters (DPFs), are very sensitive to the SAPS (Sulfated Ash, Phosphorus and Sulfur) content of the oil. Consequently, some of those car engines require lower SAPS content to keep these systems functioning properly.
The ACEA and OEMs realized the importance of using motor oil formulated with precise SAPS levels to protect those emission systems, and lower limits were established in 2010.
SAPS comprise a significant part of a motor oil additive content. Sulfated Ash is not added to oil, it is the result of additives in the oil burning and creating ash. The additives that can produce ash are most commonly used to achieve a higher Total Base Number (TBN), but also help in other areas, like anti-oxidancy, anti-wear, cleanliness, and soot handling. Phosphorus provides anti-wear properties and further anti-oxidancy, while Sulfur contributes anti-oxidancy, anti-wear properties, and engine cleanliness.
It should be pointed out that reducing the SAPS levels in motor oils also reduces the length of time the oil can remain in service (the maximum drain interval).
