The Fitch® Fuel Catalyst will:

  • Reformulate diesel, gasoline and propane allowing you to extract more energy and resulting in a more complete burn

  • Increase fuel efficiency by 5% to 12%

  • Increase power levels and reduce maintenance by reducing carbon buildup

  • Significantly reduce toxic emissions including the soot caused by incomplete combustion

  • Improve “light-off” time (20-40%)

  • Dramatically reduce bacterial growth

  • Can be installed anywhere on the fuel line

Advanced Power Systems, International Inc. manufactures Fitch® Fuel Catalysts for diesel fuel, gasoline and propane fired engines, ranging from small home generators to the largest industrial plants. Prices range from $24.95 for the F4T drop in unit, which is appropriate for the average small generator to over $100,000 for the largest of the commercial grade FHD catalysts for use on generators of 50,000 horsepower or more. The F units come with a warranty of 5,000 operating hours. The FHD units are warranted for 10,000 operating hours.


CAT 3412 Gen-Set, 3412 Propulsion Engine, 3406 Gen-Set-Hawthorne Caterpillar San Diego, CA

  1. Field test on Caterpillar 3412 gen-set on a vessel in the South Pacific.
  2. Water Brake dynamometer test on a Caterpillar 3412 propulsion engine at the Hawthorne Caterpillar dealer located in San Diego, CA.
  3. Resistive/reactive load bank test on a Caterpillar 3406 powered 300 kilowatt gen-set at the Hawthorne Caterpillar dealer located in San Diego, CA.

Analysis of Results

Engine performance (horsepower and torque, responsiveness and noise) benefited from the presence of Fitch treatment. The ramp mode data(2 sets with FFC verses one baseline) clearly indicated significant fuel savings of nearly 20% compared to baseline numbers when data are normalized to horsepower and torque produced by the engine. Also, it is obvious from the comparison of the 4 sets of graphs of the ramp mode data that engine performed dramatically better with the FFC fuel. The engine reached much higher levels of torque and horsepower with the FFC treated fuel.  Fuel savings were significant and well documented in all three evaluations. 

Differences between results can be primarily attributed to differences in the quality of the fuel used in each project. In the field test onboard the ship; savings were in the range 8.5 to 12 % in part due to the quality of the fuel supplied. In Test 2) the dyno test in San Diego we procured aged fuel that had been in storage for at least 6 months. In Test 3) the load bank test, it was decided to use the current ULSD #2 fuel supplied from the dyno test cell’s day tank. Even with this relatively high quality fuel, a significant economic benefit from employing the FFC (1/4gph) was apparent. With the normal fuel employed by the fleet in the South Pacific, the fuel savings and other benefits to emissions and engine performance will be substantially greater than this test measures. The combination of the series of three separate evaluation projects clearly supports this conclusion.

“We have had the Fitch Fuel Catalyst working on 452 generators. During this time, we have been able to corroborate savings in fuel of at least 7.6% per unit. Furthermore, we have found with great surprise, that due to the fact that the fuel is pre-treated by Fitch, it burns better and much cleaner than before thereby reducing the maintenance that was required for the units. For example, it is our custom to give maintenance to the units as per the manufacturer’s recommendation. Nevertheless, we have found our generators with the FITCH unit are in optimal condition (cleaner and with little residue) and we understand that this must clearly contribute to a longer life of the equipment.”

“We are pleased to give you our Gas Turbine Technical Data with the following details: 
Brand:  Westinghouse- USA
Model: CW 251 B11
Capacity: 39 MW
Specific Fuel Consumption: .367
Serial Number: 4658126
Fuel Consumption Reduction after Retrofit with Fitch: 5.8%"

- IR. DRS. Bardan KS. MM, General Manager, Indonesian Power, Bali

“Comparing consumption before and after the fitting of Fitch Fuel Catalyst, significant fuels savings were achieved and the Return on Investment (ROI), would likely be in the vicinity of 3 to 4 months.”
Brand: Wartsila 6L 32- output 2.3 MW
Test Fuel:  Bunker C – heavy fuel oil
Results: 4 % Improvement - Consumption reduced from .274 liters per kilowatt hour to .263 liters"

- N. Nuque, Manager-Energy Services, Philips Semi-conductors Phils, Inc. Philippines

“We have complete power house (installed capacity of 11500 KVA), comprises of total 07 Nos.  DGs Set (02 Nos. X 2000 KVA each + 05 Nos. X 1250 KVA each) and running as per production requirements.  On an average, daily HSD consumption in power house is 20-21 KL.  Recently we installed Fitch Fuel Catalyst in 2000 KVA DGs set and results are a >7% savings.  We will also like to mention that after installation of Fitch Fuel Catalyst, there is a sharp decrease in the emissions."
