Welcome...
to the Fuel Stick Africa web site;

Fuel efficiency is on everyone’s mind in these days of high fuel prices.  The world is full of fuel efficiency products and gas savers. They all claim to improve gas mileage, give you better fuel mileage or maybe even the best gas mileage.
They all say they will improve fuel economy and increase gas mileage in one way or another so it is very difficult for the layman to figure out how to get the best fuel economy from his vehicle.

No fuel saver on the market can give you better gas mileage than good maintenance so that should be the first step to fuel economy.
