Better Figures then 900kms to a tank

[polo_spec_d]

After getting back from my holiday I crunched some numbers on my fuel consumpion, 3.75L/100kms, This was a combination of city and hwy driving, but mainly hwy.

I was pretty happy with these figures even more due to that I was doing all my driving in the middle of the day and got caught in peak hour for somke off it too.

Anyone else in the 1.9TDI seen figures like these before?

NB. car still isnt empty so I could drive abit more if I wanted, But unsure if I wanna run out.

That's sensational, even for the Polo.
I've got the Golf 2.0 TDI and the best i've ever gotten is 4.5 overall, that's all highway driving with virtually no peak hour to contend with. I just can't seem to get any lower than that no matter whether I cruise at 100 or 115!
What mods have you made to improve your economy?

[polo_spec_d]

only engine mod I have is the Seat Intake. Ohh and I was running on the eco conti tyres.

[Mofo]

very impressive. I may need to look for my own polo, I'm very much interested in the fuel efficiency side of things rather than the performance.

[polo_spec_d]

ohh the polo offers both IMO. most off the time most performance mods get you better efficiency to a point, I have read (sorry cant remember the webpage) polo 1.9s getting like 3.1 and even going under 3L/100kms with strict driving practices and fuel saving mods.

Well done on getting some good consumption figures.

Just a thought, was your consumption based on the trip computer or calculated from fill to fill ? My Transporter's MFD is always optimistic, sometimes to the tune of over 20% ! Even a single fill calculation can be slightly inaccurate, as it is difficult to fill a diesel to exactly the same point each time (all that froth). I tend to use an average of at least 3 fills, so it evens out a bit.

But it is fun to sometimes see over 1,400Km as the "Distance to Empty" (not that I believe it)

I get my best ecomomy on dry roads when it is around 22-25C. I get more power when it is cooler, but use more fuel.

If I am prepared to sit on 80Kmh on flat roads I can coax my MFD to show 4.5l/100Km in my transporter, but it is so slow I am in serious danger of getting run over from behind (also it seems to take forever to get anywhere).

I dont have a trip computer unfort, the car was dead empty when I filled up, It took 45L no more. this was the first time its ever been that empty. the car was shuttering as I came towards the servo.

When I was on the open road I sat on 105km/hr. I was just so suprised to get those kind of figures with it been so hot.

I don't see how that is possible? Driving my MY08 1.9 TDI Sydney to Canberra and back in one night, 100% highway, yeilded 4.94L/100km. If your car was a Bluemotion....

How many km did you travel and how many litres did you put in?

It is possible why not?

But you forgot to mention the speed you were going when you got only 4.94L/100km?

Just a few things that affect fuel economy:

Keeping the speed around 90km/h (105km/h on Polo clock could be 95km/h in reality)
Aerodynamics
Outside temperature, humidity
Tyre pressure, type and condition
Flat long roads or hills.
Stop start
Weight the car is carrying
Mechanical condition of the car. ( if new are there any modifications?)
And the most important is the driver's experience and knowledge how to achieve the best fuel economy

Figures should be possible.

MY08 Jetta TDI 2.0
Trip from Central coast to Southern highlands @ 100km/h 4.5L/100
However the return trip Basically identically can be done at 3.9L/100
Depends on the road conditions, Down hill back to Sydney
Also found some improvements with increased tyre inflation at 40psi

Before increasing the tyre pressure my consumption to Highlands was 4.6

also no aircon on on any trips.

New audi 1.9 has a manufacture figure of 3.9 on the label.
7 speed DSG and roll resistance tyres.
So potental for better consumption than this you would think.
