Well I'm not a scientist so I can't give scientific facts smart guy. But it is a fact that I got 25 mpg this last tank and did the install at half a tank. I was just informing people following this that plan on doing that I did see an increase from previous tanks to this tank, but you just seem to lack the common sense to take the information I have provided. Look you are mentally challenged it's fine and you can live with the illusion that I'm a scientist. I have no idea what your profession is but judging from your previous post it's not mechanical. You are probably a paper pusher, which I really don't care what you do or think. I am going to sleep the same tonight and drive my truck to work tomorrow just the same. So if you don't like my thread don't post on it, and go bother someone who thinks your opinion matters. Guess what highspeed it's not me. And don't forget to keep me informed on that conversion on the Camry, really interested on how that goes. Hahaha
