Motul 8100 X-cess 5W40 is 100% synthetic oil. Designed to be used in all Euro 4/5/6 based petrol or diesel engines WITHOUT exhaust filters (DPF or TWC) requiring the standards below. Most commonly required for many Mercedes Benz, BMW, VAG, Porsche, GM and more
Widely regarded as a product with the most amount of approvals and standards possible.
Appreciated by many drivers for the sharp engine response, robust engine protection, consistent oil pressure and very low evaporation rate.
Modern engines with low-tensile piston rings are subject to potential oil loss. For petrol engines originally requiring 0W20 or 5W30, 8100 X-cess 5W40 is the ideal upgrade and will reduce potential oil loss to a minimum. For diesel engines suffering oil loss, use 8100 X-clean 5W40.
8100 X-cess is ideal for heavy duty applications such as towing or off-road driving.
For even sharper response in low to mid range, use 8100 X-max 0W40.
For highly tuned engines and motorsport, use Motul 300V for the ultimate in performance and protection.
8100 X-cess 5W40 is suitable for tuned engines with mild cam profiles (Lift, duration, ramp) and/or moderate valve spring pressure (<180psi) requiring more than 1100ppm of Zinc.
NOTE: Do not use Zinc additives. More than approximately 1200ppm of Zinc is ineffective, negatively impacting other wear protection additives and is considered Zinc saturation or Zinc dosing. If cam wear occurs, investigate mechanical or oil flow issues. Consult Motul.
High quality engine oil flush additives are encouraged, however do not use leave-in additives ('performance improvers') with any Motul engine oil products.
