Hi.  Maybe there is already some similar topic , but search at Briskoda is horrible.

 

Second time feeding the 2WD car with full tank and cannot get more then 40 littres in ( according to meeter at petrol station) after dashboard showing close to 0 kilometres left, so I did assume I am nearly on fumes. Sup3 at such situations allowed me to put 66L in to 60L tank

Issue exist with new digital dashboard as well. So  what is the max you ever put in tank ?

I pushed ours 12 miles past the MFD '0' claim and it still only took 46.7 ltrs.....so I'm thinking it can be driven around 40 miles after '0'.....?

Without filling the expansion tank it took 51 liters

Details as from Skoda Configurator today:

 

Karoq	Fuel tank capacity	+ Safety reservoir
2 x 4	50 litres	9 litres
4 x 4	55 litres	7.4 litres

 

What do Skoda define as 'safety reservoir', I'm assuming once you've used 40 litres the MFD flashes '0' miles?

 

Or does it start the '50 miles' left countdown at 40 litres?

 

When I was young (and much poorer) I used to find out exactly how far the car and how low the gauge would go before I ran out and had to pour in some (the trick was never to use it all) of the reserve from an old oil can I carried in the boot.

 

It would be nice to know exactly how much usable capacity we have.

Exactly. That what I always had in my Skodas ( and I had a lot of them) , '0' always allowed me to fill full tank + something extra. With Karoq is other way  around so far. I just need to understand do I need to recalibrate something or what.

Given the potential for an element of build-up of condensation/water and general crud in the fuel tank, I'm not certain I'd want to be relying in any on the usable capacity of the safety reservoir, particularly given the fine "characteristics" of Skoda engines! 

When I received my car, the tank was empty so I had to fill it up. It took 52 liters of diesel, while my colleague's (who got his car at the same time) filled with 49. 

I believe that if you want to trully fill the tank with diesel, you have to wait for the froth / foam  to set.

There is no "safety reservoir" in the tank , this is just a way how car presenting data to you. Additional capacity on separate location been popular on tractors before 50-60ies last century. Plus it is bunch of filters int he middle, and diesel filter is very thin and will not allow any "bad" particles to your commonrail system.

This thread is similar to many others that appeared in the early days of Octavia Mk3 section.

Basically many Octavia diesel owners were complaining that they were being prompted by the fuel gauge and 'empty' light and only managing to get 40 litres or less in.

The conclusion was that the (2WD versions) tank size was definitely 50 litres (and probably 55+ litres if run dry) but what was not clear was whether this was an issue with the diesel fuel level monitoring or a deliberate feature by the manufacturer to avoid running out, or low on fuel.

The arguments for the latter were a) to avoid the immersed fuel tank pump from overheating and b) to avoid possible damage to the very high pressure pumps and injectors that could ensue from attempting to pump 'air'.

 

The fuel status instruments on petrol engines are generally more accurate than the diesels. Read into that what you wish, but the actual tank sizes on both fuel types are the same, a nominal 50 litres for 2wd and 55 litres for 4wd.

Hmmm, never heard of this "issue" on Octy3 ( but I never owned one from the time of Octy2FL TDI I had for a while) . It was never an issue on my diesel Yeti , and diesel Sup2 and diesel Sup3 :(

I did not fill my tank first time , it was dealer.  But how its now ?

I just filled after 510 kilometers of driving. 25,75 liters with 41% remaining according to Skoda OneApp. 

So by calculating, if the oneapp showed close to 0%, max fill up  would be around 43-44 liters. 

Again, I was surprised at 52, but the response was that they filled up to the brim.

typos

After 100km visited another petrol station and top up the tank with 6L of diesel. Just to be sure that the one I used before did not sell me 50L for price of 40

 

Not bad 47 ish to the gallon

Do you have 4x4 or 2WD karoq ?

Fortunately for me .............NO

Having had a Fabia Greenline for many years I reckon what this does (with much older electronics of course) is show the range drop off more quickly than the truth once it drops below 100 or 75 miles. On quite a few occassions (& with consistent driving) I've set out with, say, an indicated 200 mile range knowing I had a 150 mile journey, only to find that it would be showing as nearly 0 by the end. That would be quite a smart way to do it - you normally know the true range but then it makes you panic into buying fuel before it runs out completely.

That is exactly what it does, on the first tank of this vehicle I ran it deliberately completely out of fuel to see what its real range/capacity was, as with its predecessor I was able to drive 60 + miles with the trip meter reading zero before it stuttered to a halt, I put 5l in from a jerrycan and the range went up to IIRC 45 miles which is amazingly accurate for a dribble over the bottom of the tank, I drove less than 5km to a filling station to refill but in that time, during the first 2 or 3 kms the range progressively and quickly dropped to zero again

 

I brimmed the tank and filler neck allowing all the foam to subside and I got in precisely the rated volume of the tank.

 

So on the MK1 and MK2 Octavia my experience is that there is a 5l "reserve" available on top of the tanks nominal capacity and this only gets used if you drive beyond "zero miles remaining" on the MFD and that the range counts down in a non linear fashion exactly as described by Simon300, when mine shows no kmw remaining I look at the trip counter which I reset at each fill up, if it reads 550 miles I know I have another 60 to drive.

 

Over my 14 years of ownership thats a lot of fuel stops saved, problem is the MK2 has much more insistent and repetitive audio and visual warnings that I bet most are refilled with 1/4 of a tank remaining.

Week ago drove to Heathrow 114 miles (182km) left car at Hotel car park. They moved the car 1 mile to another location and then returned to the original location. Car moved 2 miles in a week. Returned home 114 miles. Total mileage in one week 230 miles (368 km). Maxidot 57mpg going and 59mpg return. Range left in tank 360 miles (576 km). Total range on current tank 944km or 590 miles. 50 litre tank in 1.5Tsi manual SEL Karoq.

Who need diesel!

Exactly and petrol 10pence per litre less than diesel and no adblue to pay for as well. This engine is so quiet as well compared to any diesel.

Do people seriously mess around like this,that’s why a light comes on tell you to refuel ASAP ,does anybody need to run the car to a stop and drag every last bit of **** from the bottom of the fuel tank into the system and to pour another few litres/ gallon just too know that if a light comes on they can PROBABLY run for X number of miles,,,,,,,,,I would say get a life or always carry  a spare can of fuel ..........life’s to short .

Edited 1 May, 20197 yr by Sad555

I am not "people" I am me

 

Yes I did need to do that to (not too) know that I can (not PROBABLY) run for X miles. I do carry a 5l jerrycan, its what I used to refill it.

 

I agree life is too (not to) short which is why I dont waste it telling people that differ from me (like most) to get a life

thank you so much for reminding me of my error.that takes a very special person to remember something like that
