Maximize the productivity of your fleet

Fleet owners, customers, and drivers rely on your decisions to keep trucks and drivers safe and on the road, even when the pressure is on. That’s why our Lubricants division offers the complete line of premium Mobil Delvac products. Together, they’ll help boost the productivity of your fleet, maintain fleet costs effectively, and protect and extend the lives of your trucks. After all, if it wasn’t the best, our Lubricants division wouldn’t offer it.

Premium lubricants work better together

Using the best lubricants in the right amounts at the appropriate intervals across the entire drivetrain is a smart way to reduce your long-term costs.

The lubricants you choose can impact the costs of equipment maintenance. There are significant benefits to using premium lubricants:

  • longer intervals between oil drains maximize uptime
  • better wear protection under all conditions extends equipment life
  • reduced friction and buildup from road sludge and soot keep engines performing better for longer.

Performance integrity worthy of your equipment

Mobil Delvac™ 1300 Super

Advanced diesel engine oil that provides performance for up to 50% beyond OEM-recommended ODIs1 and an average of 50% more wear protection than required in CK-4 API engine tests.

Mobile Delvac™ Extreme

Premium synthetic-blend, high-performance diesel engine oil that provides performance for up to 2x beyond OEM-recommended ODIs. The boosted formulation contains 46% more antioxidants and 44% anti-wear additives2.

Mobil Delvac 1™ ESP

Advanced full-synthetic, heavy-duty diesel engine oil can help extend engine life while providing long ODIs1, extreme high- and low-temperature performance, and fuel economy potential3.

Mobil Delvac 1™ transmission fluids

Outstanding load-carrying, anti-wear performance transmission fluids can help extend transmission life and improve fuel efficiency.

Mobil Delvac 1™ Gear Oil

High-quality oil with exceptional thermal stability and load-carrying capability can help extend gear life and potentially improve fuel economy through friction-reduction properties versus mineral oils.

High Mobil Delvac 1™ Xtreme Grease

High-performance grease with excellent resistance to water, extreme pressure, wear, high temperatures, rust and corrosion and lower maintenance costs and decrease unanticipated downtime.

Mobil Delvac™ Extended Life Coolant/Antifreeze

Phosphate-free, silicate-free, nitrate-free, borate-free, and ethylene-glycol-based coolant that has exceptional wet-sleeve-liner cavitation and corrosion protection of all cooling system metals and that can deliver a long service life4.

2. Compared to Mobile Delvac 1300 Super

3. A fuel economy evaluation was conducted using two Volvo FH500 6×2 Euro 6 trucks, loaded to 60% payload (about 32,000kg). Testing was conducted on a track at the Millbrook Proving Ground in the United Kingdom. Corrections were applied when changes in test environment had a statistically significant impact on fuel economy. Statistically significant fuel economy benefits were observed in the Volvo trucks when comparing Mobil Delvac 1 ESP 5W-30 to a mineral 15W-40 engine oil with an average fuel economy gain of 2.6% for city driving conditions. Fuel economy improvements are dependent on vehicle/equipment type, outside temperature, driving conditions, and your current fluid viscosities.

The right grease for the right applications

When it comes to grease applications, simpler is better. That’s why we proudly use the Mobil Grease Application Guide – it’s the best system for recommending the right grease for the right applications.

The hidden costs of complexity

Complexity appears in many forms, which could be impacting your cost, productivity, and equipment efficiency.

Too many greases

  • increase the risk of using the wrong grease for a particular piece of equipment
  • product mixing leads to unplanned compatibility experiments

Under/over greasing

  • too much grease can damage seals and cause excess heat
  • too little grease can cause lubricant starvation

Storage and handling

  • inefficient inventory practices drive up the cost on the shelf
  • multiple brands cause labeling challenges, and too many products lead to misuse

Multiple vendors

  • make purchasing processes inefficient and complicated
  • conflicting product and use recommendations cause unnecessary confusion

Eliminating complexity from each of these categories can reduce downtime and increase productivity. To fire on all cylinders (we had to say it), you also need to consider where the grease will be used.

Electric motors

Electric motors are found in almost every industry, because motors operate at higher speeds (1800-3600rpm) than other equipment. They need lighter oil viscosities and higher thickener content, or NLGI grade, to stay in place. As a result, electric motors and other high-speed fan and pump bearings may require a different grease than the rest of your equipment.

General purpose

A large portion of the equipment in most facilities tends to have similar operating conditions (range of speeds, temperatures, environmental factors). A general-purpose grease can be selected to have the properties to safely protect this variety of applications.

Low speed/no rotation

In low-speed conditions, where oil viscosity alone cannot separate metal surfaces, greases may need additional wear-preventing additives to protect all components. A common example of this is molybdenum disulfide (moly).


Some applications may have unique requirements that don’t fit the above categories. Examples include grease-lubricated couplings, equipment operating in environments above 180oF, or food-production equipment requiring NSF H-1-certified food-grade grease. Greases for these purposes should also be discussed during your Lubrication Assessment.
