Now using corn to make E10 is a whole other stupid story.
Pffffftt. The stp stuff that comes in a similar can to seafoam works great,and the Lucas fuel treatment contain pib which is shown to improve fuel consumption,just don't overdose or it will cause worse consumption.
The Lucas oil stabilizer is a joke but the fuel stuff works great.
Op. I think that these manufactures are preying on peoples fear of ethanol. Ethanol is dry,so adding a tc-w3 2 stroke oil or another form of upper cylinder lubricant will not cause any harm when used as directed.
I've been using tc-w3 in the fuel of all my vehicles and my air compressors/generators at work and my service guy is amazed at how well my carbs work,cleanliness of the combustion chamber and fuel pathways.
I've been brewing up my own concoction though. A mix of a few things.
When I first picked up my hemi I was lucky to get 14-16mpg highway,now with my witches brew I can attain over 20mpg and with no wind and last night I got 24mpg. I did just change my spark plugs on Saturday though which I'm sure helped.
