Quarles For Your Business

Quarles offers a multi-functional all-season diesel fuel additive formulated to boost fuel economy, improve cetane numbers, reduce emissions, fight fuel deposits, and increase lubricity protection.

Premium Diesel provides:

  • Mileage Improvement
  • Horsepower Improvement
  • Cetane Improvement
  • Emission Reduction
  • Inhibits Corrosion
  • Controls Moisture
  • Cleans Injectors

If diesel fuel does not contain an effective detergent (and most don’t contain any), varnish and carbon deposits can clog injectors robbing you of as much as 25% of your power and performance.

Premium Diesel raises fuel to quality levels exceeding Original Equipment Manufacturers’ Specifications. It burns completely ashless and contains no metallics or agents found harmful in engines. Consequently, its use cannot, in any way, void any manufacturer’s warranty.
