my gas situation

I've noticed that I can often pump another 6 to 10 litres after the pump 'stops' for the first time. I then have to rapidly pump the gas to keep it flowing after the first 'stop', due to the pressure sensors on the pump nozzle.
This 'trick' can be annoying but it is worth it. If you do this, the result is that the top half of the tank seems to give you much better mileage than the bottom half. You will get a much better picture of your actual mileage if you do this, as you will actually 'fill' your tank. I've averaging 700km+ on a 50L tank, with about a 50/50 mix of city/highway driving. I drive very relaxed, do not use A/C unless it's boiling outside, and accelerate mildly - anything to reduce consumption. Lately I've been using premium, which I find gives me even better mileage and better passing power on the highway.
The other day I pumped an extra 9.5 litres after the pump first stopped. Give it a try, but make sure to watch your nozzle so that you don't overpump and spill gas (and waste your money).

So, my recommendation is NOT to over fill your tank.

^ I agree. Gas expands and the reason the pump automatically stops filling up is to give your tank that extra room for the vapours and the expansion/contraction in the gas tank during changes in temperature.

Good way to waste fuel and prematurely damage evap. components.

i get about 400-450 city driving i never hit 500 but most of my driving is city but if ur putting 30 bucks in and ur getting 450 u hsould be smiling plus i always hit vtec i juss love the accleration of first gear so i burn a lot of gas but w/e
tune up ur car and put the fuel injector cleaner in ur gas tank the next time u fill up all the way dont just stop at 30 bucks it costs me 45 -50 bucks to fill my tank and thats only if i hit like EMPTY the red line empty
but i noticed a big difference when i put the fuel injector cleaner in

And to the O/P if you are near oakville. swing by my area.. and I'll check your car over. If you need a tune-up, ignition timing.. stuff like that. But it sounds like you should fill your tank up all the way.. then tell us how much you get per tank.

I had no idea!!! Ahh thank you guys for alerting me to this, I will definitely stop. I'm glad I checked this post because I need to fill up my car tonight.
Wow... I'm glad I've only ever 'over-filled' my tank 3 or 4 times, otherwise I would really be mad at myself if I had been doing this for years.
I cannot believe I didn't know this... seriously thank you guys for pointing out this STUPID move on my part.

Sure.
Your fuel tank vapours are drawn out of your tank to a canister (it may be different on certain cars/models, but I'm just explaining a simple system)
There are a few soleniods that control this flow of fuel vapours. By overfilling your tank, the fuel must go somewhere, right? So guess where it goes? Past the soleniods which aren't meant to be submerged in fuel and into your charcoal canister. Under extreme situations.. it may even be drip fuel out of the vent valve. But I've never seen anybody be that stupid and overfill it that much

you know how many vent valve solenoids I sell a week? hahaha atleast 10! all cuz people overfill their tanks too damn often...I fill it to the brim when I'm headed out on a long trip but regular fill ups are to when it stops and then rounded up to the dollar

hey i get about 700-800km per 50L tank. no one mentioned that how you drive is a key factor, if you start fast and stop fast, how much you idle, i do about 95% highway driving. if you are on the highway a lot and can use cruise control try that, also, look at the tire pressure, if you want to reduce pressure fluctuation use nitrogen to fill them. also look at your air filter and fule filter they arent too expensive to replace and are considered routine maintenance to good fuel economy.

They're common on pretty much every make vehicle.
