According to the U.S. Energy Information Administration, the average U.S. diesel price is now around $5.64 per gallon. (check here)
For diesel owners, this materially changes the cost of driving.
$140 per tank
Cost for a typical pickup with a 26-gallon tank.
$80 per tank
Cost for a smaller diesel with a 15-gallon tank.
$30-$50 More
For many drivers, that’s $30–$50+ more per fill than what they were used to. This isn’t a marginal change. It compounds quickly across weekly use.
Small MPG Gains Are Now Large Savings
At lower fuel prices, a 5–10% improvement in fuel economy is meaningful.
But at $5+ diesel, the same improvement becomes financially significant.
Even modest efficiency gains now translate directly into measurable dollar savings, making improving fuel efficiency one of the few immediate ways to offset higher costs.
Better Fuel Means Better Fuel Economy
Modern U.S. diesel fuel is typically:
- Limited in detergent content
- Lower in cetane than optimal
- Lower in lubricity than required (According to the Engine Manufacturer's Association)
Over time, this contributes to:
- Loss of performance and efficiency
- Wasted fuel and soot deposits
- Increased component wear
Correcting these factors improves diesel power, performance and MPG and protects your fuel system

Fuel Savings Cover The Cost of AR6500
If AR6500 Diesel Treatment offsets its own cost through fuel savings: Injector cleaning, combustion optimization and lubricity come at no additional cost.
With diesel at ~$5.64 per gallon, fuel economy has a direct and immediate financial impact.
When fuel economy gains more than offset the cost of maintaining a clean and well-lubricated fuel system, improving diesel quality with AR6500 simply makes sense for diesel owners.
