RBP’s High Performance (HP) Additive is an ultra concentrated total diesel fuel system cleaner and lubricity enhancer with an added 5% cetane increase for all types of diesel engines.
  • 5% cetane increase.
  • 10% average fuel mileage increase.
  • Unmatched concentration. 16oz bottle treats up to 500 gallons. 1oz per 32 gallons of fuel. Average competitor's product ratio is 1oz per 5 gallons of fuel.
  • Improves the performance, fuel efficiency and longevity of diesel engines while reducing deposits, black smoke and emissions.

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Quality product Purchased this for my diesel Jetta and seemed to help increase mileage on a 1800 mile journey. Hopefully the cetane additive will help continue to provide some longevity to my engine. April 16, 2015
