Put in nearly 73l into 67l tank diesel X3

Put in nearly 73l into 67l tank diesel X3
Happened to me this morning. Filled up with the gauge showing quarter tank and the range about 120kms with the orange low level fuel light on for about 2kms. When the pump meter showed 72.7 litres i stopped the attendant and paid for my purchase. The owners handbook says approx 67l tank capacity but i know that that is supposed to be when the tank is full (when the pump should shut off the first time?) and with the filler pipe and some space above the fuel level available for expansion, but this is 5l more with i assume at least another 5l or more which was in the tank when i got to the petrol/diesel station. I recall some forum member had a similar situation with his i think also X3 some time ago (searched for the thread on the forum but cannot find it). Also cannot remember what the outcome was of his discrepancy problem. Must say that the needle on the gauge only moves from the full mark after about 250kms but that has got nothing to do with the capacity of the tank. Could have something to do with the fact that the low level light came on with the gauge showing quarter tank. Will appreciate it if some one could direct me to the previous thread. Thanks!

Yeah I also remember the thread. One of the petrol stations, the attendants were pumping fuel into bottles and hiding from customers.
If car was total empty, maybe 5 litres in piping could be possible at a push, but you weren't even totally empty. Seems weird. Who knows if the petrol station pumps are correct? How would we know if the pump says 60litres, but its actually only put in 50litres? Can these machines be tampered with to give incorrect info? Great way for petrol stations to rip us off.

Gee that is really odd. I would assume maybe the petrol attendant ripped you off (but I could be wrong).

RE: Put in nearly 73l into 67l tank diesel X3
No way the attendant was ripping me off as i was standing right next to him. Asked him about how often the pumps are calibrated. At first he did not understand the question and then replied that they do it about every two months. As this particular petrol station has the second cheapest diesel (the cheapest garage is only 1c/l cheaper) at R11.62/l for 50 ppm that i know of, it would be so easy (i think) to just adjust the pump to show more diesel than what is actually going into the tank (if it is at all possible to do that) and make up the difference in price! Am not saying this is what is happening here but is surely not impossible. Could some one in the trade please explain how the pumps are calibrated and what discrepancy is acceptable, if at all? Thanks. Btw., am not accusing any one here, was just wondering!

The pumps themselves belongs to the garage brands for example Sasol, caltex etc.
The garage owner must report a faulty pump and then a compay like example Prowalco comes out ...fix it and recalibrate it. It's all digital now and works with specific software programs not available to the general public
All pumps must be serviced a certain amount of time every year ....was 4 times a few years ago
The pump technician can actually pick up on a pump if there was any thing done to it and if a person /owner are caught fiddling with a pump he face loosing the franchise and also criminal charges.
A few years ago 100ml per 100l of feul was a acceptable variance
That being said I'm certain there still is some crooked owners.....mixing feuls.....paraffin in diesel etcThumbdown

RE: Put in nearly 73l into 67l tank diesel X3
Did the attendant stop filling up the first click of the pump or was he trickle feeding your X3, as they like to do? If the latter, he was using up the space reserved for the tank's airlock. An extra six litres is not so bad. It could be worse.

There was something in the papers last year about people being charged by car rental companies for filling up the VW Polo Vivos that they returned. It turns out that they were filling up to the first click of the pump, as they are supposed to. The rental company then goes off and trickle fills it, adding another 13 litres. The size of the Vivo’s airlock is well-known amongst Volkswagen owners. It is indeed possible to squeeze 58 litres into the Vivo's 45 litre tank, at the risking of doing damage to the vehicle.

So just tell the guy fill up to the "first click." They will know exactly what you are talking about. When I am in a hurry, I just ask for R500. That way they can actually swipe my card while the pump is still running.

Hi Solo man,
This is a common occurrence on the E83 X3's. The filler neck (not part of the 67 litres, takes 7-9 litres of fuel in addition. I filled 82 in mine!

RE: Put in nearly 73l into 67l tank diesel X3
Seems to be the solution to the X3 problem then as i have noticed that it takes a loooong time to fill the tank. When i stopped the attendant the tank was still not full! It was quiet there this morning so i asked him to carry on with filling the tank even after the first "click" as i was not holding up a customer waiting for me or the attendant. Am trying to see what the consumption is on this car but will now have to take the average over a larger number of fill ups. Thanks for clearing up the problem and restoring my faith in people!

I was able to put over 73lt into the tank on both E83 x3 models I have owned. It's a common thing for the e83.

RE: Put in nearly 73l into 67l tank diesel X3
Thanks for all the input, seems to be a common thing on the E83 X3. Will not worry in future then! Btw., my car's fuel gauge only starts moving from the full position after about 250kms and the light came on with the gauge on quarter full. It does not seem normal? Is there some way to "adjust" the gauge maybe via the hidden menus??

RE: Put in nearly 73l into 67l tank diesel X3
i have also noticed that there are 2 rate of flows on most if not all bowsers. Most of the time when i ask the guy to check the pressure and wash the windows he puts it on the slower rate. I would safely assume that using the slower rate would fill more as the extra space in the tank has a little more chance to fill up before the first click.

I filled up my VW last week and the tank is 60 litres, had about 40km left on the range so possibly about 3 litres left. They guy used the slower rate even though I didn't ask for anything else to be checked. It took much longer and it had only clicked at about 60 litres. I wasnt paying full attention at the time and asked him to stop when it clicked again. He filled in slower and eventually at 63 litres i asked him to stop as it hadnt clicked by then.

One way to check is to take a clearly marked container along and fill up to the marked level. If the difference between the level for example of a 2 litre container is 150ml or more i would be worried.

RE: Put in nearly 73l into 67l tank diesel X3
I have often wondered about the benefit of the extra few litres you get from trickle filling. The garage sells more fuel, but what else? I don't make it through the week on a tank anyway, so I usually fill up twice a week. Waiting for an extra litre or three just annoys the heck out of me.

Reason for filling to the brim is trying to determine what the exact consumption is on my car and also how much, if any, the obc is out.

I believe filling to the first click would average out after a few tanks, but provided the flow rate to fill is the same.

Go to the same petrol station with an empty 2l coke bottle and ask them to fill it up. I once did that and managed to fill the bottle with 2,8l of diesel. The owner offered me free carwash after confronting him Rollsmile

Done that before, you will be shocked to see the results and might want to punch someone. I don't know if these fuel pumps are being calibrated regularly or not

Thanks for all the advice guys!. This particular petrol station is 70kms from me, so not so easy to follow up on all the container filling advice, but will keep that in mind, thanks.
