I am sold on this.

I have a 2011 Chevrolet Tahoe with the flex fuel option. I have run it on E-85 since I have had a few thousand miles on it. I have added a bit of this Lucas treatment every time I have added fuel My Tahoe runs the same as it was when brand new. I get 21 miles to the gallon with this treatment. E-85 here in California is $2.99 per gallon when regular gas is $4.50 a gallon. If you run E-85 try this.
