I'm not endorsing this product. Does anyone know if it really works or is it just more snake oil? Here's the blurb for this fuel additive:
Ethos FR is a unique combination of high-quality, non-toxic, specially designed esters that uses only the elements of carbon, hydrogen and oxygen.
This combination of low molecular weight cleaning esters and high molecular weight lubricating esters, reformulates any fuel whether its' gasoline, diesel, methanol, ethanol, hydrogen, LNG, compressed natural gas or bio-diesel.
EPA laboratories tests confirm that EthosFR is clean upon ignition and ash less upon combustion. EthosFR is free of carcinogens.
Ethos FR is non-toxic, non-hazardous and works with any fuel used in cars, trucks, buses, RV's, ships, trains and generators. Ethos FR reduces fuel costs by producing a net gain in mileage above cost.
Ethos Environmental offers a cost effective solution to help industry meet environmental regulations and relieve skyrocketing fuel prices. Hundreds of millions of miles of road tests have proven that commercial fleets on average increase fuel mileage between 7% and 19% and reduce emissions by more than 30%.
