Motul 8100 X-cess is a 100% synthetic engine oil formulated to satisfy API SN and ACEA A3/B4 standards. The API SN standard requires superior cleanliness and protection against oxidation, wear, and deposits compared to the previous SM standard. The ACEA B4 standard requires extreme detergents and dispersants to combat viscosity increase from soot in Direct Injection diesel engines. By meeting or exceeding both of those standards, Motul 8100 X-cess also carries approvals from BMW (LL-01*), Mercedes-Benz (229.5), Porsche (A40**), Renault (RN0700 and RN0710), and VW (502 00 - 505 00*).
X-cess 5W-40 also meets the performance requirements of GM-Opel LL B-025 (Diesel) and FIAT 9.55535-H2, 9.55535-M2, and 9.55535-N2.
* Does not meet BMW LL-04 or VW 505 01 specifications. Motul 8100 X-clean 5W40 meets both specifications.
** Does not meet Porsche C30 specifications for Cayenne V6 and Diesel engines.
