Improving fuel consumption

In B & Q the other day I saw this stuff for the petrol tank that claims to economise petrol etc... it was 5 and looked pretty good stuff.
But a friend who i was with told me that the stuff is as useful as a chocolate teapot...
can anybody reccomend anything that will help the consumption of fuel!?

Also he also said that usually the fuel gague in most cars are incorrect... is this true!?

Sorry about the spelling... im tired!!

There are all kinds of magic potions out there with claims like reducing the fuel comsumption,reducing friction inside an engine or finding the solution to world peace,but to be honest I am not convinced.......

The easiest ways to improve fuel economy is not to carry any excess weight when not neccessary,remove any roof racks/bars when not in use,and to drive more carefully(accelerate and brake gently etc).Also,there is a difference between the fuels available,so although supermarket fuel might be cheaper,you might find that your car is significantly more economical on a branded fuel.

I'd rather push my Alfa than drive a BMW....

I would have to agree with that - I have found supermarket fuel to be poorer than the leading fuel companies. I would be weary of adding anything to the fuel - long term could spell valve problems - fuel companies go to a lot of research to optimise their product. Depending on your engine and the type of journeys you do; experimenting by filling up with 'super' (optimax) unleaded might help. But of course the extra cost defeats the purpose! The simple things as mentioned are probably the most help - also correct tyre pressures make a significant difference.

As above.

If your car is serviced properly in all respects then the best way to improve your MPG is to drive economically, anticipation of the road ahead and do everything gently.....

Acceleration, braking and keep your speed down.

After reading this thread i thought it would be the best time to say something on Renault Forums.

Recently i developed a problem with my Megane and thought it would cost alot of money to sort out.
After thrashing it it started to lose power and started to miss fire.

I went to Halfords and bought a bottle of SP Fuel Injector Cleaner, put a full tank of 97 Octane fuel in and a full bottle of this injector cleaner in and since then the problem has now gone away. It's also made my Megane run alot better and it's alot better on petrol.

I believe these products do work but have to be careful on which products you use and how often you use them aswell.
