Fuel savers

Hello friends, I would like to know about their opinions about the fuel savers that exist in the market ... I have a Ford Aerostar 3.0 V6 of 88 and do 4.8 km per liter, it is an expense well for the engine and the path in which it moves but it could be better if it put any of these savers that are seen there ...
I wait for their opinions ... Merry Christmas ...

The truth I have caused that type of display in three different vehicles, made consumer tables and everything, and the difference is not relevant, they are the same or want to improve a liter no more than that, it is more like a placebo effect. Happy parties

My opinion and experience One of the best options is that you use high performance air filter are as a cone type more power and saving fuel.

Hey your car is a good gasoline. I have a Chevrolet Ventura 2000 engine 3.4 and gives me 7.0 km per liter and on a little more road.

If this little Gaston with respect to yours ... counting that mine has more than 20 years old, and the path in which it moves is very hard, they are hills and mountains with unchanged roads ...
a while ago I mediate in the city and makes me 6.8 km pòr liter on open road and in good condition.

The famous economister or fuel savers as you are called, only serves when you demand it, at low regime it does not work practically, I would be thrown more for a carbudor change depends on the mouths that it has combines you to put if it is that it has 2 mouths or more, some that open the other mouths per empty, are complicated to fix when they fuck but it helps to reduce some consumption
