2005 AWD Escape Hybrid
Best Interstate tank trip MPG 39.02 (scangauge II) for 402 miles on I-70, 10.3 gallons used over mostly flat terrain.

Best Interstate tank trip E30 MPG 34.6 for 271 miles along I-80 in Indiana and Ohio.

Best multiple road tank trip E30 MPG 36.2 for 202 miles in Southwestern Pa.

The kit I have is EPA certified too.

What that means is, testing shows the use of the kit and ethanol will NOT increase emissions beyond what the vehicle emitted with the factory equipment.

Thus, if you have an ULEV, EPA says you will still have an ULEV ( or better ) using the kit and ethanol.

EPA cannot, and will not gurantee this will not affect car performance, or manufacturer warranties. All EPA says is: "These kits do not make the car exceed emission standards."

So while "EPA certifed" is a good thing, don't read more into it.
