Features and Benefits

Mobil Delvac 1™ 5W-30 Advanced Synthetic is an outstanding lubricant solution for modern and latest engine technology equipped with emission After-Treatment devices. It was developed by ExxonMobil to maintain unsurpassed oxidation stability performance to meet long oil drain intervals and support low maintenance efforts. Mobil Delvac 1™ 5W-30 Advanced Synthetic keeps at the same time critical and hot engine parts clean, also while bio diesel fuel components are used, for long and efficient engine life. This feature, in combination with the sophisticated additive system, ensures exceptional engine wear performance and supports long engine life. The low ash formulation protects at the same time all exhaust after-treatment parts required to meet emissions regulations.
