I like putting Lucas into my gas tank before a monthly summer fill up. My old friend was a mechanic and told me to do this. I listen to mechanics, especially ones that are my friend.

it does work

project farm recommended it so I tried it twice. I let 10k miles go between usage. my tank miles went from 370 to 450 after a bottle was finished. the acceleration improved too, no more sluggish petal. I will continue to use every 10k miles.
