I must say I'm very impressed with my 1.4 octy combi. I drove my wife to gatwick from mansfield last week, fully loaded with 70kg+ of luggage plus 2 kids. I drove nice and steady in eco mode down there and back I did a steady 65-70 mph and got 52+ mpg. I decided to pop to Skegness for the weekend and got an average of 61mpg on maxidot. I've read in previous posts that the maxidot can over read but I'm still incredibly impressed. I'm getting diesel economy in a petrol car. In my previous yeti 1.2 I'd be lucky to get near 40 mpg.

Andy thats great to see the car has a doubling factor, you get more econony, I get more fun. Thats what I call a win win.

My 2.0 TDI is only getting 39mpg urban in Eco. Still on the first fill up so hoping things will improve

Are you getting diesel economy from a petrol car or just driving incredibly carefully ?

The best I have seen is an in journey of 52MPG on the Maxidot - my car over reads MPG by just under 3MPG over a tank.

 

I have decided not to use Eco mode as it does not seem to save fuel.

I certainly don't drive foot to the floor everywhere but the pace of the 1.4 is plenty quick enough to keep up with the traffic. I stick to the speed limits and that was my result. Of course if I give it plenty of welly then the economy drops off much more than a diesel does but it's good to know what I can achieve.

I agree Andy, I too am super impressed with the 1.4TSi engine. I had one trip around the M25 where I never really got going due to the variable speed limit around the Heathrow stretch, weight of traffic between M40 and M1, roadworks between A1 and M11. I pretty well did 55mph for the entire journey and the maxidot showed 67mpg!

By the same token I had one journey to work that I thoroughly enjoyed and the maxidot showed 21mpg.

Time will tell, but I expect long term average with my normal driving style to be high 40's (real mpg) with my normal urban driving style and cruising at 80 where I can on the motorway, which will be within 10% of what I got from my 1.6TDCi Focus under similar conditions.

Incidentally, I haven't done enough fills to be certain I have the true average yet, but my maxidot looks to be about 6% too optimistic so far.

It really is good as my 1.6tdi is averaging 53mpg (fuelly) and shows 55mpg average on trip computer.

Individual journeys - 55mpg average on commute which is 30 miles mainly A roads, cruising around 75 to 80 mph

49mpg on trip around London

65mpg driving as carefully as possible at 55mph on motorway.

So I would say on your figures above the 1.4 tsi is better overall than the diesel.

Well, Classic, not quite as good I think. The really high numbers are not really representative, my 67mpg run is unlikely ever to be repeated! You also mention 55mpg on a 30 mile mainly A-road commute cruising at 75-80mph. Impossible to be accurate without seeing the exact route, but I'd guess my 1.4 would reach no more than 50 on the maxidot for this type of journey, maybe a touch under, depends on how much fluctuation in speed due to traffic/corners.

 

Still, it's close enough for me to not consider the cost difference in fuelling the car to be too significant. Having owned a 1.6TDCi Ford and having experienced real world fuel economy for a car with a ridiculous official mpg figure I bought the 1.4 thinking that I needed it to do at least 40mpg average to consider it not a problem, but with hopes of getting nearer to 45mpg. Right now I think I could see something nearer 48 average with my normal driving style (which got around 52 in the Focus), so you can see why I'm so please with it.

Geek42 I've had diesel cars for the past 10 years , and I actually went to the dealer intending to get a 1.2 or 1.4 petrol Octavia. Cost wise I need to get 45 to 50mpg to keep my commute affordable.

I ended up getting a diesel as it guaranteed 50mpg, less depreciation etc, with me doing around 18k miles p.a.

It looks like I would have been ok with my initial instinct to get a petrol. Unless my diesel mpg does improve significantly as the engine gets more miles under its belt.

I guess it depends on how long you intend to keep it as well. I tend to ignore the resale value aspect as I keep my cars until they're not worth enough for it to matter, but if you swap it after 3 years it's going to be significant. I also don't do the mileage that you do.

 

I just looked these up on WhatCar again (I have been suggesting in another thread that the 1.6 shouldn't be their favourite version) but the insurance group difference is actually more than I realised. If you factor that in with the road tax saving, resale value and even a small advantage in terms of fuel economy and there is a definite cost difference.

 

My car is also fully run in as I bought it with 14k miles on the clock. I have no idea whether that really makes a difference or not!

In my ****-poor mpg's defence, I travel a 3rd of my tiny 10k miles p.a. at silly O clock in the morning so, flat out, pedal to the metal is my fun time. Hence, low 20's high teens then matched by some other locals roads in traffic gets me just below 30mpg, thats ok I only use to get 42 mpg from my mk2 2.0 TDI. I have had 58 on the maxidot using cruise control eet at speed limts so, the car is capable of economy, it just ain't my bag.
