John Wyatt 18.5 MPG in his 1990 Lincoln Town Car

I have a 1990 Lincoln Town Car and got water in the gas. I tried another fuel treatment and I guess it got the water out but my mileage was down to 16.4 mpg by the dash computer.

I tried your 5.25 ounce fuel treatment on a half tank of gas and my idle smoothed up and mileage went to 18.5 mpg. After a second bottle, it is now up to 18.8-19.0 depending on how much in town driving I do which is good for a large body car with a 5.0 liter in it.

I,ll be using it from now on and my next oil change I will add the synthetic oil stabilizer.

Thanks Lucas for such great products that really do what they claim.
