Motul Sport 5W40 is a very high performance, 100% synthetic Ester-based oil for modern (and highly tuned) turbocharged motors, formulated to be the road equivalent of Motul’s famous 300V oil. Motul Sport provides the greatest protection against engine wear, oil burn, oxidation, and high-stress foaming, while providing enhanced engine response and performance with stable oil pressure and robust oil film strength. Motul Sport is the oil to use if you demand a lot from your car.
