Having just bought a new to me 2011 Elegance estate DSG 170 TDI. I think the 60 litre tank is small considering it does 45-47 mpg. I have read some people post that as one of the niggles on a separate thread. 

 

Can anything be done about this. I mean it shares its body with an Audi A6 I was told for avant and estates?

 

How about taking an Audi A6 tank and replacing the Superb one. Sounds simple enough right ?

 

Assuming Audi got a 70l one ?

 

No relation between any Audi A6 and the Superb II. The Superb is based on the Passat B6 platform. You could see if any variant of the Passat or Superb got a larger tank and go from there.

thought the superb was based on the octavia platform, which is based on a golf?

I heard both cars were built on the same production line maybe wrongly. 

I do recall a Passat around 9 years ago had a 70lt tank 

I thought 90%ish of all VW based cars were built on the BQM style platform.

Is a range greater than 600 miles important enough to you to go changing the tank?

What about buying a black 10 litre fuel can, fill it up and carry that in the boot with a suitable funnel ?

 

I have i 70 litre fuel tank and get excited about getting to 700 miles before filling up and then find my self doing it at 600-650 miles.

put a few cans in the boot

The Octavia Mk3 and Superb Mk3 use the MQB architecture., the mk2 Superb predates MQB.

Thanks for clarifying that Gerry.

 

Hang on a moment, don't you put fuel in Gerrycans, perhaps you could sit in the OP 's Boot

Drive more gently, more mpg! Besides I remember having a big tank on a 1995 5-series, it would top £100 to fill up!!

I have i 70 litre fuel tank and get excited about getting to 700 miles before filling up and then find my self doing it at 600-650 miles.

I wanted to get 600 miles with some buffer on the maxidot to cover stuck in traffic. The idea of carrying a smelly diesel can is not what I had in mind really. Just thinking what could be done to either improve MPG or improve the capability/range of the fuel. 

If a used tank is a simple swap what a transformation though ?

Do you drive 600 miles non stop?

 

I would not put a smelly fuel can in a car either, passengers would be rather displeased.

If i spilt some filling it i would clean the diesel off just as i do if my hands get diesel on them.

 

Improving MPG is usually down to a well serviced vehicle and hypermiling.

I have come from and still have a 1.9 Octy which did 700 miles if I tried on 50-55 litres. Think the SMF conversion pushed the mpg to 58 and that's not driving gently. I knew the DSG Superb was going to cost more to run. But I just need to get 3 days commute out of it. I really hate filing up. Plus all the more annoying when the maxidot says I can get 200 miles, so it's nearly possible to get 1 more days driving out of it. D mode is quite boring. I tried the gentle runs but my right foot gets restless when there are chances to make up gaps on the motorway. 

LOL, so no big deal then, just too much trouble filling up.  3rd world problems, bigger car, small fuel tank and in a hurry.

I do approx 96 miles each way and takes anything from 1h50 to 2h30. Traffic permitting on the M1/6. I like to think the new to me Superb has been serviced ok, based on the history. I even still manage to get diesel on my hands with the Shell gloves. Another thing I only fill at Shell and the one in the south costs 5ppl more for normal diesel. 

What is hypermiling? 

Well why use Shell if it is standard diesel / ie the same as all other diesel,

you might as well go to supermarkets unless paying for Premium Diesel.

Now we are going to start a whole new debate. I won't use supermarket fuel. Shell is close to home too. Sorry to sound so negative. 

Well that is why there are choices, you pays your money and you get what you paid for, standard diesel for a little more from a filling station close to home or convenient for filling up every 2 days.

I did think about this also, what improvement am I expecting though ?

More power/torque and better mpg.

Not always if you make use and enjoy it?

Plus stress on components like DMF perhaps ?

Put me off doing it before

It depends on how you use it - you can kill your car on stock anyway.

I was surprised at the tank being so "small" , I've got a mondeo as well and that has  a 70 litre tank. When you do a lot of long distance trips  it's a bit less hassle . 10 litres is a very long walk ;-)

That's the confusing bit. The Superb 2 (3T) is based on the B6 platform which was also used for the 2001-2005 Audi A4 and S4 (8E).

 

The B6 Passat, was not on the B6 platform.  It was on the A6 platform.  Go figure.

It's my fault the tank is small.  It's a saddle tank.  There is a hump in the middle so that it clears the drive shaft for the 4x4 versions of the Superb, like the one I have.  You have the same tank, with hump, just no drive shaft.

 

Having said that, the 60-65L in there is enough to get me Melbourne to Sydney, so I reckon it's enough.
