I have just been out on a test drive an Octy Estate in elegance trim. What a quality car! Very impressive all round, so much so that I am now going to purchase one.

Before I do I am trying to ascertain the difference in mpg between the 1.9 & 2.0(140) diesel units on offer for the Octy.

My thinking is that the 2.0 unit would need less working so may not be very different in real terms to the 1.9.

Has anybody used both for any length of time, over the same sort of routes, that can accurately give the mpg differences between the two?

I tested the 1.9 which was adequate but probably would prefer the 2.0 providing there was not too much difference in the fuel consumption.

The vast majority of my driving would be urban with 20% or so on the motorway.

Thanks, Nellsey

There are other (long) threads on fuel consumption, and the general picture seems to be that there IS a big difference between the 1.9 and 2.0 TDI.

I have the latter and struggle to get much over 46mpg despite the official figures - I hope that will improve as the engine beds in - only 8000 miles at present. My father-in-laws RAV4 diesel does better than that!

There are claims of 60+mpg from some 1.9 TDI owners. Obviously these aren't controlled tests.

That said, I like the performance of the 2.0 TDI, although I haven't tried the 1.8 TFSI which I think would be my preference now diesel is so expensive.

Tonight with my 1.9TDi 105bhp it was showing 56.5mpg and that was a gentle drive around my town whilst working but if i drive it harder it was reading 49.8mpg.I think is quite good really and the car has done 16000 miles.

The vast majority of my driving would be urban with 20% or so on the motorway.

I have an 06 1.9TDi Elegance Hatch bought at 1yr old with 14k on the clock, my driving is semi urban / rural A roads with some motorway - average fuel consumption 51mpg (using brim to brim) - trip computer is approx 5% optimistic. Best and worst (over a full tank) 60.1 and 48.5. The 60.1 was a 550 mile round trip 98% motorway (remarkably free flowing A1, M18, M1, M25 and back) with average speed on the computer of 62mph. The 48.5 was winter: frosty mornings, mainly short trips with a couple of 50 mile runs out into the Dales.

A mate has the 2.0TDi Elegance Hatch - he averages around 43-44mpg and his mileage is probably 40% motorway. It is however a company car and the company pays for the fuel

I would describe the 1.9TDi performance as adequate: cruises all day on the motorway at 80mph, doesn't feel the hills and has enough acceleration left for safe lane changes. On the rural A roads it cruises up hill and down dale, has enough oomph to overtake (but wouldn't we all like more!?) Round town? Don't know what to say! It is quick enough off the mark to get into the traffic, does 20-40 mph with the best of 'em, has good brakes, light clutch, and is comfortable enough for the interminable waits at traffic lights.

I haven't driven the 2.0TDi in an Octavia but have driven it about 500miles each in a VW Sharan and a Passat. Fantastic drive but I did find the 6 speed box a bit of a pain on the busy motorway - need a drop from 6 to 5 in both cars to get decent lane change acceleration on a hill if the speed dropped below 65 or so. In the 1.9 (5 speed box) I boot it in 5th from as low as 50mph and it just goes. Maybe just me being lazy

I've heard people say that the 2.0 is more refined - I have never driven my mate's 2.0 Octavia but been a passenger - the sound is different - when it is working hard the 2.0 seems to be a gentler, higher pitched sound whereas the 1.9 is deep, gruff and growly. When they are cruising - no real difference.

Elegance spec? Love the toys!

Rear parking sensors are brilliant.

Cruise control - how did I ever get by without it!

Dual zone climate control? Definitely my favourite - in the car with SWMBO - she can be warm and snug while I have cool air flowing from my vents; in the car on your own - set the driver's side to warm and the passenger side to cool then use the passenger air vent to get a flow of cool air to your face while your feet get warm or you demist .

Auto dimming rear mirror works beautifully at night but you can't dip it on a dull day to block out a flickering motorcycle headlight - so just move over and let 'em past.

Auto wipers - just work!

"Jumbo" box - must have pretty small elephants in Czechoslovakia and the armrest makes it a bit awkward to get the handbrake - but you get used to it.

Conclusion? I am more that happy with the 1.9 - still love driving it after 12,000 miles in 11 months almost trouble-free ownership. Do I wish I had forked out an extra £1000 for a 2.0TDi? In all honesty - definitely not. DSG gearbox? hmmmm.... maybe!

Id say get the 2.0 tdi, then when its bedded in get it remapped:thumbup:That's what my mate did on his Golf 2.0 tdi and he was averaging 46mpg, not bad considering he had 180bhp under his right foot:thumbup:

Paul.

Caution if you are going for a brand new one fitted with a DPF as most replies to previous posts on mpg are for pre 08 (pre DPF) motors

62mpg with my 1.9Tdi on a steady sub 70Mph run to North Wales with a full boot and tank of diesel.

Regular get mid to high 50's (note.based on the fuel computer, not calculated) on motor way runs, and low 50's in urban traffic not uncommon either.

Test drove both the 1.9 and 2.0 before settling on the 1.9 for reasons of cost of buying, insuring, taxing etc. Have needed the extra power occasionally, but think supermarket diesel i have used recently and a duff DMF have disappointed, more than the over all lack of power from the engine. New DMF and a few tanks of decent diesel hopefully will improve performance slightly.

This topic has come up many times now but i will add again that computer read outs are useless, they are only showing what it is at the moment, you can get 100 mpg at times, it does not mean anything . However we have a Octy Elegance 140 dsg and now with 25000 miles on the clock the average mpg is 42 mpg and that includes towing a caravan 1350 klg for about4000 miles. The roads travelled have been really mixed, i could not tell you percentages.

Best way of doing it is to work out either the actual brim to brim calculations and/or the range you have achieved in a tank of fuel

Brim to Brim my 2.0 TDI 4x4 is doing high thirties round town on brim to brims which is similar to the maxidot reading. Cruising in Ireland last year the computer was showing high forties/low fifties.

I've got a 2.0 Elegance with 45,000 on the clock. I'm averaging between 46 - 48 according to the on board pooter. 500 miles easy enough on a tank. When I've driven the 1.9 (I had a brand new 1.9 Ambiente for a week as a coutesy car from the dealer) it was significantly better and much easier to get 50 + mpg. The best I've seen on a long motorway run is 56mpg running around an indicated 80mph. Giving it some welly though sees a drop to the low 40's .

Oh and I was under the impression that DPF's were only fitted to the VRS model with the 170 TDI engine ......

'08 1.9 Elegance Estate here.

Get 55mpg without really trying. 61mpg if I'm careful

That's on mainly back lanes and B-roads on a 20 mile commute.

Only 1k miles covered so far so everythings still relatively tight - expecting it to get better over time as my old Mk1 PD130 Estate did.

...i will add again that computer read outs are useless, they are only showing what it is at the moment, you can get 100 mpg at times, it does not mean anything.. .

Not strictly true - the display can be set to show instantaneous readout which , as you say is prety near meaningless (varies from 9mpg under hard acceleration to 199mpg down hill), but it can also be set to show an average mpg for current journey (set 1) or average mpg since last reset (set 2). These figures are far more use but in general are 5% or so optimistic.

Got my Octy estate 2.0TDI on 1st March 2008

Done 3000 miles so far

I'm getting good MPG. It really depends on how you drive it.

200 mile motorway dash got 49MPG overall - Trip computer said my average speed was 66mph.

Driving 30 miles to work (Mway, A & B roads) I get 47 to 56 MPG overall depending on the location.

My overall average is 48.8 - Confirmed by several brim to brim fills. I find that the overall average on the on board computer is within 1 MPG.

On motorways I use the cruise at 76 (80mph on the dial reads 76mph on GPS).

If I drive it like I need to get somewhere and throw it around a bit I get low 40s.

I test drove the 1.9 but the 2.0 is much better. My only regret is not getting the maxidot as the dealer didn't show me one I didn't know what it was!

Book vaules are 51mpg and 55 mpg respectivly.

Oh and I was under the impression that DPF's were only fitted to the VRS model with the 170 TDI engine ......

Nope - the 4x4 has one as well (or at least mine does!

Thanks for the replies, they have been very helpful. I think I will opt for the 1.9.

I am sure the 2.0 makes the Octy a better drive but the extra economy from the 1.9 will make the difference for me. Not only that it will save a few quid on the purchase price:D

I think I will have a look round for a demonstrator first, although some demonstrators seem to be just as much as a new car sometimes.:confused:

Some quick maths at worst case:

Diesel @ £1.25 litre = £5.70 gallon (today at least!)

1.9 average 50mpg = 11.4p per mile

2.0 average 45 mpg = 12.6p per mile

so 1.2 pence per mile extra in fuel

10,000 miles = £120 per year

Its a fraction higher on the Brown (sorry green) road tax so say an extra tenner.

So an extra £130 per year for the 2.0...

Yes the 2.0 is more to buy than 1.9 but this should be reflected in resale value, ie the 2.0 will fetch more.

Dealers have around 8% to play with so take the list price, subtract 8% add £100 as a dealer tip and thats your purchase price!

Before I got the octy, I drove both the 1.9 and 2.0 TDI (PD) engine variants. I had an exhaustive test drive, and in the end opted for the 2.0TDI. Yes its slightly more expensive to buy, but the residuals are better.

The reason I went for the 2.0, was the way the car drove. The 2.0 engine is a 16v unit, the 1.9 is an 8v unit, so the 2.0 just seems to drive better. The six speed box on the 2.0 is a godsend on the motorway and makes for quiet relaxed cruising. My MPG is really good and working out in the mid 50s (600 miles per tank). The extra 35BHP is also handy for overtaking.

If you can, drive both back to back and you will see what I mean.

I see you are still talking about computer readings and i think you are fooling youselves, just doing brim to brim a few times might give you an idea at that time but unless you do what i do and that has been since new to record every drop that goes in.And thats why i get 42 mpg average over 25000 on 2.0140 bhp dsg box . One of my runs is from the south coast to Essex using A21 M25 M11 and i recod betime i get there roughl 58 and one time 62 mpg , but as i said its meanless.

I've had two 1.9Tdis and both cars have bettered 55 mpg in real-world driving. The current car (08 reg) is slightly better than the older (06) car I had. Best Mpg was 71.9 mpg on a gentle drive along A 272 to Horsham, the other day!

My last tank (real world, not computer) averaged 55MPG, the computer reading was about 60ish.

Hi: As MPG is your concern go for the 1.9. Even though the 2.0engine doesn't have to work as hard as the 1.9 it will always use more fuel because it's bigger with more power (it's obvious)

The difference is very small though. The 2.0 has different gearing and more of them. at 70mph on the motorway the 2.0 is doing significantly less rpm than the 1.9.

Using brim to brim, I can get 48 MPG driving my 1.9 TDI DSG around town. Day to day driving in town it's 42 mpg and about 46 at 70 on the motorway. My car has completed 6k.

Love the DSG

That's not bad for a DSG!
