Overfilling (venting) VRS Mk. II fuel tank.

Featured Replies

Yesterday, for the second time I managed inadvertantly to get more fuel into my VRS than I expected.

As a result I have managed to get about 500 miles from a single refill.

The previous calculated MPG was therefore 29.6!

I now believe that I understand how this happened - TWICE.

The only space available near a pump meant that the pump was on the "passenger" side of the car.

I suspect that because the hose was under tension and the nozzle didn't slot in straight the button was depressed.

God alone know what the point of this stupid "overfill" button is?

 

 

ps -  A VERY HAPPY 2015 TO ALL VRS DRIVERS :)

I believe it is for long journeys. And why are you so sad that you managed to fill the tank?

Happy 2015 to you too.  I think I mentioned - in a previous thread of yours about this - that this 'overfill button' is not intended to be pressed by the user ever (note, no mention of it anywhere in the owner's manual). I believe it gets pushed by the tank cap being screwed in, for some purpose to do with the vent system of the tank. During refuelling, unscrewing the cap 'unpresses' the button, presumably to minimise vapour emissions during refuelling or something. It's only because the button is relatively easy to press accidentally that people have discovered that they can get extra fuel in this way, which is fine for diesel owners, but not a good idea at all for petrol owners.

In short it's not a stupid "overfill" button, it's a safety mechanism to stop a completely full tank of petrol exploding.

Don't do it on purpose, it's not safe like it is on diesels as diesel it not nearly as volatile or combustible.

I only ever do it before a long run. Extends the tank range by quite a lot.

no harm this weather 

Really simply dealt with.

 

If you are near the reserve and it is showing a 50-60 mile range,

just do not put in more than 40 litres.   

 

& you you are filling up at other times, even Brimming,  be sure you are not venting it.

Just pay attention to how much fuel is going in.

You are standing there pushing the guns trigger after all, just look down it.

When venting it usually needs more than one push of the slide to get an extra 7 litres or so in.

Putting the nozzle in the filler should help.

Shouldn't push it unless its wonky

I got 39 litres of 97 RON in today - allegedly after covering 440 miles!

Six weeks ago I managed to get 54.65 litres into a tank that is described as having a capacity of 45 litres.

That's seems like a lot of room for expansion.

I still think that Skoda might have dreamt up a better way of catering for expansion.

I used to do this on my vrs when I travelled down to Kent and back (230 miles each way). Good way to get the most out of my 16p off a litre at Tesco  :D

 

The last trip I did, the needle didn't move off the full for 139 miles and then proceeded to complete 535 miles before I had to fill up on 5 mile range

The Mileometer & Trip computer is pretty accurate with either 205 /40 R 17 or 215/40 R17 Tyres on.

You might get nearly 1 mile difference between the 2 readings over 100 miles with different tyres on.

The Trip can read different on the Maxidot from the one on the Speedo.

 

So the Mileage showed is kind of what you cover.  

 

The Tank is said to be 45 litres and it is not far away from that,

and you can get it to take pretty near 54 litres when not fully empty.

 

Skoda just used the parts they have, and if you know of the risk of Venting and you do not want to,

then it really is a case of paying attention & not putting too much in.

I wish my Rapid 1.2tsi was like this. I can only do 52 miles and it moves off of full [emoji19]

My Citigo does over 100 miles before it moves. I think the Tsi is a very thirsty engine [emoji19]
