I live a few hundred yards from Morrisons and their petrol station which is always amongst the cheapest hereabouts, if you ignore the 0.2p saving you'd get per litre at Asda! In my current car and SWMBO's, I always run the tanks low and then fill to the brim. Plan to do the same with the S3 when it arrives.

Filled up earlier. 49.8 mpg and a monstrous 734 miles.

 

 

Seeing as the fuel is always drawn from the very bottom of the tank via a flow and return system, I can't see the problem with running the tank right down to empty. 

 

 

unless they have changed the design, the return flow fills up the resovioir on the lift pump assembly (so the pump never runs dry) and then a small ejector nozzle piped from the discharge of the pump encourages fresh, cooler fuel from the tank to be drawn into the bottom of the chamber through an NRV flap

 

The only problem I can see with letting the fuel get low is the temperature of the fuel drawn in will be hotter as a smaller mass of fuel will obviously get hotter quickly. Whether this affects long term life of the pump is anybodys guess, they seem to be pretty reliable. On the flip side the fuel no longer passes through the cylinder head like on a PD so it will probably pick up less heat anyway.

Is there still a finned fuel cooler under the car like Skodas of old? or have they done away with it? Maybe that was to compensate for the larger heat gains from the old PD design....

I was going to mention that, i've had a look under mine and havn't seen one, but I may have missed it. I'm also not sure where the fuel thermostat is now, I presume they still have one but is not on top of the fuel filter like it used to be

So far i can only get 600km  or 360 miles on full tank but its 2.0TSI  not diesel  

When i comes to fuel efficiency my last tank was 70l and I drove 1200km with it.

80% highway / 20% city.

1.4 TSI ACT.

How miles from a full tank ?

 

i know we have the MPG thread, but how many miles have you managed to get from a full tank to fuel reserve light / how low dare you go?

 

I'm only 1000 miles in now, so not done a full tank to empty run as yet as the car was delivered with fuel plus a couple of ?25 top ups.

 

I have got a 550 Mile drive at the end of the month from West Yorkshire via Kent > France > Belgium > Holland. Hoping to get there on a full tank, car will be fully loaded with luggage 2 adults, 2 kids. 

 

let say 50mpg,  550 miles, 11gallon of Diesel require which is 50 litres.

 

It could be close..

Keep it at or just below 2000rpm through the gears and you'll make it on a tank, the Yeti (2.0tdi 150) gets 600miles + fully loaded on a long run

I pulled around 650 miles fully loaded to the max from Uk, France, Belgium, Holland and into Germany.

I managed 767 miles on a full tank, that was through properly economical driving and running the tank down to 0 miles. The boot was still loaded up with work gear though. 

 

Normal driving yields much lower miles per tank I can assure you. Average range on a tank seems to be around 600-650 miles. The CR190 has done 12.5k.

Do you find it's fuel brand dependent on how many miles you can squeeze out of it?

Looking at my Fuelly figures the most I've filled up is around 61 litres, and it's saying I've done 778 miles on that amount, but an equal fill gave me 709 miles.  My motorway to urban driving is around 10-20% (115 mile commute with only 3 miles not on dual carriageway). Car is a 1.6 TDi and I sit on Cruise quite a bit (A14 allowing).

 

Edit: Just added my last fill up from Friday which I'd missed, seems I did 813 miles on 64.4 litres!  Loving the efficiency of this beast!

I'm not sure yet, if I'm honest. 

 

I've always filled up with BP regular diesel from day one, I've never filled any of my Skodas up with supermarket fuel. That's not a dig at their fuel, it's mainly due to there being BP garages on my common routes to and from work.

 

I'm currently running my second tank of BP Ultimate. It looks like I'm getting slightly better mileage from the Ultimate, but I have nothing to back that up with apart from my subjective observations. As we all know, fuel consumption measurements are a nightmare for consistency due to the variables caused by driving. 

 

I'll see how the car is once I've used up this second tank of Ultimate - which won't take too long. 

Normally get about around 500 miles out of a tank of Esso 97RON fuel using local Lincolnshire roads (i.e. never quick or constant speed).  Will be trying the local Tesco 99 when I next fill up when we return to the UK as that is about 10p a litre cheaper than the Esso.

 

Did manage to hit 101mpg consumption for a 15 mile journey the other day, took driving down a mountain in the alps to do it but hey it was great to see it compared the journey the other way which gave a live consumption regularly of 15 or below...........

 

2.0 TSI 220ps DSG

Re not letting the engine run on dregs I was always told not to as there was a risk of picking up some of the crud at the bottom of the tank. I also remember being told that the fuel pump relied on being immersed in the fuel for lubrication, if it ran too low the pump might be damaged. That info might be model specific though and I can 't recall which car I was driving at the time.

Generally it isn't ideal to run a tank down to empty, I only do it very rarely anyway. I do lots of motorway miles, so the tank doesn't sit empty for very long. 

 

I think the fuel also helps to keep the lift pump in the tank itself cool as well. 

Ok, i might be the winner on the other side of the spectrum with the worst.

 

Done 1 full tank only in city driving with heavy traffic at least 4 times (meaning you stare at the same red light for over 3 times with minimum movement)
