700km to a Tank in a GTI!

[kaanage]

to be honest, when gtidave had his little rascal (pog gti, worked well), i was surprised - he would cruise in higher gears than myself for in-and-around-town duties.

You need to get serious and start shifting at 1200rpm and cruising from 50km/h onwards in 5th, Scotty. The Pod will easily do this on flat roads. Of course, with the SuperPro torque arm bush, it might give a pretty serious massage

do you guys have a vent function? a little button on the inside of the fuel mouth?

Yep. flat6 certainly knows as he gets 10-15 extra litres (I get 10.75 more). I used about 57 litres before chickening out and filling with my last tank.
The stupid MkVI Golf can't be vented so the Polo can actually hold more fuel than the Golf

Assuming the tank holds ~45l without pressing that button, I've ran mine 20-30kms past showing zero fuel/kms left and still get 38l in the tank. I really should try this button trick, when I usually average mid 8's to mid 9's, an extra 10l tank capacity is needed. 45l is too small a tank IMO.

seangti, you'd be amazed by how much vent space there is. You can just push the button with the end of the nozzle and keep filling (check after adding an extra 10 litres if you want to stop at first click level). If you are just about to start going on a long trip, you can fill it right up to the edge of the filler neck.

Would one of you petrol guys mind running your car dry (with a small container of PULP) to find out the actual tank capacity of the 9N(3)? I did this with my previous cars.

I'd do it except that diesels need to have the air pumped out of the fuel lines if run dry.

How would this work? Until first click, until all vent space gone, until petrol is gushing out?

When cruising on highways etc i refill when I do one of my rest stops (every 2-3hrs of driving). So it doesn't really matter whether i can cram 45L or 50L into the tank. One of the rest stops will line up with the gauge heading for the red zone.

Sometimes I wish I still had my dear lil pog. Anyway, I'm pretty sure mine never got anywhere near 55l capacity even after using the fuel filler button trick and that was standing at the pump cycling b/w pressing the button to filling up more.mMost I got was an extra 5-7l at most and that was fill'd to the neck.

soo. i didnt even know about this,
when are you ment to vent it?? after you get the first click or before u start filling??
how long do u hold the button for??

How would this work? Until first click, until all vent space gone, until petrol is gushing out?

Either when it will click immediately with the nozzle fully inserted or until all vent space gone right to the neck (where petrol will be gushing out if you keep going with the fill trigger fully grasped).

Anything else is not going to give a reasonably precise measurement (right to the neck is better but not advisable for petrol cars if not going for a longish drive straight away).

when are you ment to vent it?? after you get the first click or before u start filling??

You can hold down the button from the start and fill with it depressed but you'd better be on the ball else you'll get covered in fuel. It's better to fill to first click and then vent, then fill and vent with the nozzle slightly retracted.

Venting before filling and not holding down the btton wont do anything

You can tell when the tank has vented as you can hear the air rushing in (it sounds like the car is sighing).

does it degas any on its own thou??
like if your not doing this, your only going to get the standard 42-45 sorta thing ay

[Blitzen]

The best I have done so far is Braddon BP in Canberra to the BP at Wandong on the north side of Melbourne... A distance of 650km, and I was still showing 60km to empty with no fuel light on.

to you, and to anyone else who has a question about the vent function: think of it like this - there's an air pocket at the bottom of the tank, and pressing the vent "knob/button" in the filler neck, releases air from the bubble. so, you fill up, the fuel nozzle will click, you press the button, you'll hear the air escaping whilst the fuel "sinks" lower down into the tank, allowing you to put more fuel in.

in my case, i usually vent about 3-4 times, filling up until the fuel comes right up, then venting for 10 seconds until the air stops escaping, then repeat.

the only thing is that they reckon you "shouldnt" use the vent function unless you're going to drive a hundred or so clicks before parking it in the sun etc etc (because of the gasses expanding).
