Mobil Delvac 1™ Advanced Fuel Economy diesel engine oil

Mobil Delvac 1™ Advanced Fuel Economy 5W-30 is an advanced full synthetic, high-performance diesel engine oil that meets or exceeds leading industry and original equipment manufacturer (OEM) fuel economy specifications.

Mobil Delvac 1 Advanced Fuel Economy 5W-30 engine oil features an advanced low-ash formulation that delivers exceptional protection for most engine and exhaust aftertreatment parts. Its cutting-edge technology provides:

  • Best-in-class fuel economy potential*
  • Extended oil drain interval (ODI) potential up to 3X the average OEM ODI recommendation†
  • Long engine life and reliable operation in a wide range of applications
  • Emission system protection

Tested and developed with the consideration of different diesel fuel qualities, Mobil Delvac 1 Advanced Fuel Economy 5W-30 engine oil was designed to protect engines with the use of biofuel components. Mobil Delvac 1 Advanced Fuel Economy 5W-30 engine oil should only be used where an API FA-4 oil is recommended by the OEM. Before using this product in an engine, users should consult recommendations as shown in an owner's manual or other service bulletins.

Mobil Delvac 1 Advanced Fuel Economy 5W-30 diesel engine oil is recommended by ExxonMobil for use in:

  • Heavy-duty, low-emission diesel engines where API FA-4 is recommended by the engine builder/OEM, utilizing technologies such as diesel particulate filter (DPF), selective catalytic reduction (SCR), continuously regenerating traps (CRT), diesel oxidation catalysts (DOC) and exhaust gas recirculation (EGR)
  • Sophisticated heavy-duty high performance diesel engines where API FA-4 is recommended by the engine builder/OEM with turbo-charger, direct injection and low emission designs, featuring all types of exhaust after-treatment technology Direct-injection or naturally aspirated and turbocharged, diesel-powered equipment
  • On-highway short-haul and long-haul trucks and buses

*Relative to conventional 15W-40 engine oil, and within Mobil Delvac 1™ product range.
Actual fuel economy improvement dependent on vehicle/engine type, outside temperature, driving conditions and the viscosity of current engine oil.
†Average OEM ODI recommendation based on recommended oil drain intervals from major U.S. engine manufacturers using API CJ-4 oils for a variety of service severity levels and engine models. Average OEM ODI API CJ-4 recommendation to substantiate multiplier claims is 31,750 miles. Results may vary based on vehicle/engine condition, driving and environmental conditions. Consult OEM or ExxonMobil before implementing extended ODIs, especially if the equipment/vehicle is under the OEM’s warranty.
‡Based on measured viscosity increase in the Volvo T-13 test.
