So is this additive something you plan to use EVERY fill, or is it a periodic thing ?? As using it every time will offset any fuel savings surely ?!?!?!
Gonna order the 5ltr tonight and see what the story is, contacted fasteronline and no extra postage to N.Ireland. So all is good so far.
Just filled mine up since the additive went in. Got to a petrol station tonight with the red light on and 589 miles on the clock since last refill. Trip computer estimated 20 miles left in the tank and i have no doubt i could have done that had i needed to go that much further.
I estimate this stuff has saved me £10 at least on that one tankfull. Next time i fill up it should have paid for itself and saved me some pennys.
Don't you guys tend to find that people get a bit annoyed with you at the pumps when you stand there measuring out the stuff into the tank though?
As above, it is easy to measure. just fill up the top bit and pour it in.
Here is what my trip computer and fuel gauge was reading this morning after my journey to work (trip reset on last refil. The display on the right shows MPG over a 48 mile journey with lights and aircon on sticking to speed limits on A+B roads):

You could guess or get a bottle with markings on it, a prev 500ml bottle or another cheapo additive/oil with a measurer on it? thats what i'm going to do, have one here so just clean it and keep some in the car.
