Alaskan fleet trusts Mobil Delvac™ oil to weather extreme conditions  

For drivers hauling freight for Bighorn Enterprises in Fairbanks, Alaska, engine performance can be a matter of life and death. The roads they travel span barren, brutal wilderness, where weather and road conditions test a driver’s mettle and a truck’s durability.

“We deal with extremes,” says owner Joshua Bennett. “The temperatures can drop to 65, 70 below zero.”

Bennett says it’s crucial to protect his fleet — 45 power units, along with construction equipment such as excavators, bulldozers and loaders — to keep his business productive and profitable despite hauling to destinations as remote as the North Slope and Prudhoe Bay.

Saving by switching  

As to why he trusts the Mobil Delvac brand, Bennett says seeing was believing. “I used to use a different oil brand, and a friend of mine showed me the differences of a test that he had done on two trucks with a hundred thousand miles on them, which convinced me to switch to Mobil Delvac,” Bennett recalls. “You couldn’t tell [the engine lubricated with Mobil Delvac] had a mile on it.”

Weather-ready diesel engine oil  

Extreme weather conditions call for diesel engine oils, such as Mobil Delvac™ Extreme oil, that deliver long oil life even in severe environments. Its excellent low-temperature performance allows for increased oil flow to critical bearing surfaces at startup and controls low-temperature sludge formation in stop-and-go service.

Mobil Delvac Extreme premium synthetic blend diesel oil is formulated to minimize costs even in severe environments by helping to:

  • Extend engine life
  • Boost wear protection
  • Provide long drain intervals
Mobil Delvac™ Extreme engine oil with two times the OEM recommended oil drain intervals

That’s why trucking fleets and owner-operators trust Mobil Delvac Extreme to help them save time and money by delivering outstanding equipment protection even in harsh conditions.

*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.
