I tried this twice on a car with over 200k miles, once through a vacuum line on the intake manifold and once in the gas tank. Didn't notice any improvement on performance or mpg (I've been tracking mpg for yrs at every fill up.) Then I tried Barrymans a few months later and my mpg improved by 1 to 1.5 mpg avg/tank. Now I pour a bottle in the gas tank every 6-8k miles. A bottle cost about 4 bucks.

This stuff definitely helps. It's much better than the easy to find brand-names at Walmart, etc., most of which I've tried, and never noticed any improvement in my cars' performance or drivability.

I'm not sure about the price. I think you can buy it for pretty much this price at Autozone and Advance Auto, but I could be wrong.

That's old school. I use Toddler Snot
