Don’t skip or delay service-it’s critical to help your vehicle achieve maximum uptime and a long, reliable lifespan.
What kind of fuel should I use?
Heavy-duty diesels are designed to run on diesel fuel with a high cetane rating, like 45 or higher. Cetane refers to the fuel’s ability to ignite quickly, which is important for diesels. Using a lower cetane fuel can lead to hard starts, stalling, and rough running. Biodiesel blends of B20 (20% biodiesel, 80% petroleum diesel) or less can also be used in most heavy-duty diesels. For the best performance and to maintain your warranty, check your owner’s manual for the recommended fuel type and blend level.
How can I improve my vehicle’s fuel economy?
Several factors affect a heavy-duty vehicle’s fuel efficiency:
*Maintain proper tire pressure — Underinflated tires can lower gas mileage by 0.3% for every 1 PSI drop in pressure of all four tires.
*Remove excess weight — For every 100 pounds of extra weight, fuel economy can drop by up to 2 percent. Remove unnecessary equipment and cargo.
*Observe the speed limit — Aggressive driving like speeding, rapid accelerations and heavy braking wastes fuel. For every 5 mph you drive over 60 mph, you use about 10 percent more fuel.
*Avoid idling — Idling for more than a few minutes wastes fuel and money. Shut off the engine if stopped for more than a few seconds.
*Ensure filters and components are clean — Replace air, fuel and emission filters as recommended to allow for efficient engine operation. A clogged air filter alone can reduce your mileage by 10 percent.
