No, the terms low-SAPS (SA â¤ 0.5%) and mid-SAPS (SA â¤ 0.8%) are often used incorrectly in the industry. C3 is a mid-SAPS category, and the SA for C3 is between 0.6% and 0,8%. Otherwise, it would have to be C4 (low-SAPS, SA â¤ 0.5%) or both C3 and C4 at the same time. However, according to the PDS, it isn't. Therefore, it's mid-SAPS, with 0.6% â¤ SA â¤ 0.8%.
Thanks for this. What is C2 then?
A1/B1: removed in 2016
A3/B3: to be removed in 2020

An oil can be certified for both C2 and C3 at the same time if it satisfies the stricter fuel-economy limits of C2 and has HTHS â¥ 3.5 cP.
Also note that ILSAC oils such as Mobil 1 and Pennzoil Platinum that claim to be full-SAPS A5/B5 (or A7/B7) are often mid-SAPS, not full-SAPS, but since there is no lower SAPS limit in this spec, they can be certified for A5/B5 (or A7/B7).
