W 100% syntetyczny - najwyższych parametrów - paliwooszczędny olej silnikowy specjalnie opracowany do silników samochodów grupy PSA wymagających oleju oficjalnie dopuszczonego do używania zgodnie z wymaganiami PSA B71 2290. Specyfikacja ta wymaga ochrony silników w których mogą występować problemy z detonacyjnym spalaniem (LSPI Low-Speed Pre-Ignition). Przeznaczony do silników benzynowych i Diesla (HDI wyposażonych lub nie w DPF, FAP) a szczególnie do najnowszych (od r.m 2017) silników benzynowych turbodoładowanych z bezpośrednim wtryskiem paliwa.

Engines compliant with Euro 4, 5 and 6 emission regulation are fitted with sensitive exhaust gas after treatment systems. Indeed, Sulfur and Phosphorus inhibit catalytic converters operation leading to inefficient exhaust gas treatment; and Sulfated Ashes clog DPFs leading to shorten regenerating cycle, quick oil aging, higher fuel consumption and engine power loss.
PSA for its B71 2290 norm requires oil to able to endure the most severe thermal constrains along with PSA modern after treatment systems compatibility. PSA B71 2290 standard is suitable for most PSA Gasoline engines and most Diesel (including DPF versions) engines, except for “BlueHDi” Diesel fitted with SCR (in this case use MOTUL SPECIFIC 2312 0W-30).
Turbocharged gasoline engines with direct injection have a certain risk of sporadic pre-ignition phenomena in the combustion chambers. This type of sporadic abnormal combustion resembles metallic noise from combustion chambers and is sometimes associated with a short power loss. This phenomenon called LSPI for Low Speed Pre-Ignition, or also Rumble, generates very high pressure peaks in the combustion chamber that can lead to piston damages and ultimately to engine destruction. For their latest-generation downsized gasoline engines, which are equipped with direct injection systems and turbochargers, PSA has developed the B71 2290 standard for engine lubricants in order to guarantee the perfect integrity of these gasoline engines facing the risk of these abnormal combustions.
MOTUL SPECIFIC 2290 5W-30 meets all these very demanding requirements of performance and durability set by PSA, including in particular for the PSA B71 2290 norm for PSA vehicles, this LSPI requirement to perfectly protect all direct injection turbocharged gasoline engines, and the full compatibility to biofuels use such as biodiesel, when using biodiesel at a mix ratio of up to 10% (Biodiesel – B10).
