I dont know if this is repost so ill put some **** in. Have any of you guys heard of MPG-CAPS. My uncle was selling them and he told me to try them. He said that it mixes with your gas then when it gets sprayed out of your injectors it will coat the cylinder wall, less friction and also leans your fuel out a bit to increase hp and mpg, but the video is pretty ------- stupied so thats why im asking you, bullshit or what.
here is a video of it.

 

pyramid scheme ftw

repost

they dont work

 

they work and are sexy. Ive also heard of the mpg caps and thought they simply raised the octane rating or something similar but i could be wrong.

From what i heard they do work but the cost-benefit ratio isn't that good to justify putting them in over just buying more gas. My information could be completely faulty though
