Delo with Isosyn® Technology. Lets You Go Further.
Properly lubricating the inside of a heavy-duty engine requires more than just creating a protective film. Quality heavy-duty engine oils must also disperse soot and control sludge in order to help guard against loss of your engine's life.
With fuel costs a constant concern, maximizing fuel efficiency is an important component of improving operational efficiency. Delo products have long assisted in reducing operating costs and improved fuel efficiency is one way we help. Switch to one of Delo’s fuel economy products, and you could see up to 4% fuel economy improvement compared to SAE 15W-40 oils. Actual results will vary depending upon vehicle type, load and other driving conditions.
