Reduce Diesel Regeneration & Carbon Pollution +/-70%

ECO Systems Fuel Enhancers work by reducing the size of the Hydrocarbon molecules 
increasing the Reid Vapor Pressure in fuel. The results are a 
more volatile, combustible & cleaner burning fuel.   

How it Works

Diesel RVP   +/-.6% to +/- 1%
Gasoline RVP +/-7.4% to +/-8.2%

ECO Fuel Systems, LLC is committed to protecting and preserving our environment.
Using the ECO Fuel System to reduce Hydrocarbon Pollution (40% to over 70%) your helping to preserve our environment, reduce downtime, maintenance costs and saving money.

NEW RELEASE! Cobra Clean; Clean Diesel Particulate Filters without heat. 
GREAT News! Coach Buses; No forced REGEN's after installation, saving fuel (8.24%)! 
     No RISK! 90 day money back satisfaction Guarantee (BBB A+ Rating 10+ yrs)

REGEN's and your Budget - Proven solution to the Diesel REGEN problem.

Everytime a Diesel Engine goes into a regen cycle it wastes fuel (4-10 gallons) and can take 30-45 minutes to complete. See the test results for a fleet of 20 EMS units. We have documented results on all motors: Trains, School Buses, Coaches, Trucks, Marine. We don't eliminate regeneration cycles, we reduce the amounts and severity. REGEN Cycles are required 40% to 70%+ less often, Forced REGEN's almost entirely eliminated. This leads to reduced maintenance costs and a longer life for expensive parts like Diesel Particulate Filters and Fuel Injectors. 

The ECO Fuel System is a guaranteed proven solution that has been around for over 10 years (BBB A+) and is successfully installed on tens of thousands of diesel and gasoline engines. We invite you to do a No Risk test on your fleet. Call or contact us.

Are Regens Hurting your Budget? REGEN 101

Diesel Particulate Matter is more regulated than ever. Almost every fleet is dealing
with the high cost of maintenance and down time.

Systems may vary, the goal is to reduce tailpipe emissions. The DPF does this by capturing
the soot and burning it out. Vehicles that do a lot of stop and go 
driving may require
down time or highway run time to clean their Particulate Filter

Ambulance (EMS) Regen problems solved! 
Test results for a fleet of 20 EMS units with ECO-4's installed showed a 72%+ reduction in Diesel Regeneration Cycles. (See Results) We don't eliminate the regeneration cycles, but by enhancing the Reid Vapor Pressure and the Air to Fuel Ratios in fuel they are required much less often. This leads to a longer life and less maintenance for some expensive parts. Average annual savings; $1,000 to over $3,000/yr. 

Coach Buses - Transit
Recent on the road testing at PSTA (Pinellas Suncoast Transit Authority) in St. Petersburg Florida showed very favorable results. As a test, ECO-4 units were installed on 10 high mileage Gillig Coach Buses with Cummins ISB 250 HP motors. Average daily miles driven was +/-300 miles at an average speed of 16 MPH. These buses previously required out of service Forced REGEN Cycles 1 to 3 times per week. On average they consumed +/- 900gl of diesel fuel per week. After installation all 10 buses did not require any out of service Forced REGEN's and have remained on the road. Due to cleaner burning fuel and less REGEN Cycles fuel consumption was reduced by 8.427% (75+gl/bus savings/wk.). PSTA ordered more ECO's and will be outfitting their entire fleet of new and older buses. ROI +/- 16 day's.

School Districts & County Governments
The call to action for School Boards and County Governments is to reduce

pollution. The ECO Systems Fuel Enhancer is being used by over 200
School Districts & City Governments, on everything from squad cars
to heavy equipment. Many over 10 years. (References)

Our averages are based on Real World Testing by our customers. Commercial customers, School
districts, County government, City government, and Consumers. This data has been accumulated
over the last 13+ years. Lab tests help explain some of the physics
of the ECO Systems, but in-service
testing has been the only method that proves the technology.
Your vehicles, Your data, Your fuel and
Your driving, thus giving you your real results, and money
in the bank, not the fuel pump. The better
test protocols involve make sure that good historical data
is available, then installing a minimum of 5
units (for a fleet customer) and not telling the drivers. Record fuel
consumption, regens, and other
metrics over a few weeks. Nine times out of ten, there will be a fuel
savings -
many times it's considerable.
