Dudes. look it up in the search bar. read the links and give it a try and stop complaining about gas prices. ive used 1 ounce to around 11 litres (roughly 4 gallons) and i thought something was melted inside fuel sensor because the needle was not moving. my stang is acting like a really fuel efficient V6... not my probe (plzzz) but maybe accord? i dunno buy a glass measuring cup and some acetone at home depot or wherever and do it! im giddy around gas stations now. no wonder oil companies dont want us to know. remember less is better. thanks to the senior guys who posted all those links so i could do my own research. :SNSign: im going over to probetalk now to brag.
