Mobil Synthetic Heavy Duty Engine Oils

Mobil Delvac formulation commercial engine oils are available in the following viscosity grades


  • » Mobil Delvac 1 5W-40

  • » Mobil Delvac 1 SHC 5W-40

Excellent low temperature flow

Mobil Delvac synthetic lubricants are engineered to reduce internal friction, which results in outstanding flow characteristics at low temperatures and components are lubricated more effectively, especially at a cold start-up.

Viscosity stability

Higher viscosity index translates to a more stable viscosity across a broad temperature range. As well as excellent low temperature performance, Mobil Delvac synthetic lubricants resist thinning at elevated temperatures, resulting in protection across a greater operating temperature range.

Improved oxidation and thermal stability

Stability – Improved oxidation stability and thermal stability in Mobil Delvac synthetic lubricants results in less viscosity increase with age and better deposit control, which can lead to fewer oil changes and less downtime, with the potential to save time and money.

Excellent wear protection

Newer vehicles must be able to handle higher torque and increased shock loads. Mobil Delvac synthetic drive train lubricants offer excellent anti-scoring performance, which helps increase gear life at high speeds and under shock loading conditions.
