Do the fuel saving kits really work?Anyone here tried or tested any?
Answers:
I think they tried these on Mythbusters and actually got worse gas mileage. Keep up the maintenance on your car, that's the best way to get good gas mileage.
if they do why havent all new cars got them fitted?
watched a documentary on one on the discovery channel and they did not work.the only slight difference they noticed was maybe like getting a mile or 2 better than average per gallon and that was on the express way..and that could be due to many factors
They do to a point. The principles behind most of them are solid well-proven ones. The throttle body spacer version would be more effective than something you just insert between air filter and throttle body.
None of these things work. If they were cost effective we would all be driving about with them.
what kits are you talking about?
