doc_phibz -> RE: What MPG and HP increasing devices NOT to buy! (12/3/2005 1:36:01 PM)

good question. same as when all the hybrid cars, such as the prius, came out saying 72 mpg now they claim way less. they prob. test the product in optimal coditions. they prob. used a vehicle with the wind pushing at their back going down slope, with stuff like synthetic oil, lucas injection cleaner, octane booster, etc...that's my theory on it. or instead of using a car, they just put it on an engine dyno and ran it at low rpm's constantly. i was reading an article about how they were able to make such claims on the hybrids, they used only dry conditions, with winds at the car's back on down slopes, with smaller tires, and some other crap.
