I know diesel is getting cheaper but even so, I was really pleased to see that 40 MPG+ is effortless in the TSI even after a spirited and fun push with a BMW X5 M 5.0D. This is Farnborough to Lincoln today with the usual standing traffic or slowing down to ogle the burnt out lorries southbound near Grantham on the A1, average speed cameras etc. It is definitely more economical than my old MkII VRS.

Don't do this to me. I fancied the tsi but have just ordered tdi dsg as I couldn't justify 35mpg petrol vs 50+ from diesel.

Don't forget to double check the economy using a manual calculation.

 

The onboard computer on some cars is designed to flatter!

It is a good engine.

Computer is almost dead on with a tank to tank calculation.

on a good run I've seen 52mpg.

Best tank to tank I've done is around 47mpg i refilled at 519 miles, the trip included London and motorway traffic as well.

The computer is spot on in my car.

Ive recorded every drop of fuel Ive put in it in the aCar app, and it gives the same number as the computer.

I've been pretty impressed too with the economy of the TSI. It's a big car so my thoughts were if I average 35ish I'll be happy, especially coming from a 2.5T Focus ST. My current - manually calculated - average is 42. That'll do nicely.

I get nowhere near that! on a run from Canterbury to Burnley (300 miles) I got an average of 37 mpg doing around 80 mph on clear parts. I then reset it and since recording my day to day travel which is an average speed of 22mph over 1500 miles I was averaging 28 mpg.

I then switched to using v power 99 octane unleaded and after 2/3 tanks I started noticing better mpg I now get 31 mpg with mostly town driving and a 6 mile commute to work which involves 2 junctions of a motorway so engine is still not warmed up properly so don't see proper motorway mpg. However... They have currently put roadworks on my 6 mile commute and set the cruise at 55mph and I'll get back 38mpg including warmup on just 6 miles! If I wanted an economy drive I'd have bought the diesel. I'm happy with 31 average around town as I have a few mates with St focuses, BMW 325's etc and they get 20 ish around town and both are slower so I'm happy with that!

How do you find the tsi in comparison to the St focus? Power wise, drivability etc? I had a play with a new focus St eco boost the other week and I was side by side with him all the way, in fact I think I could have pulled in front if it was a longer stretch! The tsi is very impressive for a 220bhp (quoted) engine!

I haven't seen anything like that on mine, but still she's only on 700 odd miles and if it hasn't been a town run, I have been starting to stretch her legs when possible.

Off for a good run later in the week, it'll be interesting to see what she does, mind you the bit round M25 probably wont help !

It's much smoother when giving it the beans. The ST was like driving an old PD TDI. A big lump of torque then runs out of puff when you get higher up the rev range. Obviously the ST wins when it comes to engine note and exhaust note. It's one of the few negatives about the Octavia for me. The exhaust note is nothing special.

I think if you tried you could do better though.

I am pretty close with my 103tsi

I'm mostly on town driving and averaging 30mpg on a tank is good going and only possible with a lot of concentration.

 

When the car was all new and shiny my average was about 24-26. I've calmed down a bit since then

 

 

I long for motorway journeys to see the numbers rack up.

I'm closer :-)

Sit at a steady 50 ish mph and I can get mid to high 40s but over a full journey with a little traffic low to mid 40s.  Over a full tank I've got 41-42mpg a couple of times now, and 39+ is easy if it's got a lot of motorway driving involved.  My long term average is currently showing 39.2mpg over about 23000 miles.  Previous long terms have settled at 36.5 mpg.  Car is run in now at almost 9 k miles.  Always gets super unleaded, usually shell.

 

What impresses me most is even short journeys in London traffic I get 28 to 35 mpg, stop start makes a big divergence feel.

I think my original point was to show, you can have a 2.0 TSI and get decent economy going up and down motorways, easily keeping up with the traffic and whilst it's not 50+ Mpg, still affordable. I am not for one moment thinking that it is as economical as the 1.4 TSI or TDI's, especially in colder weather or town journeys but on the motorway it's good. I live in a fairly rural area and my long term avg over 5000 miles is 39 Mpg which is decent. Petrol suits my circumstances plus I don't have concerns over remapping to squeeze some more performance out, fake exhaust outlets, DPF regeneration etc. If I lived in a large city and had to do astronomical mileage it would probably reconsider. 

Never seen anywhere near 40mpg within mine. My long-term average after 11k miles is 27.7mog with best ever tank providing 36mpg (almost all on the motorway).

Still, it beats my old Subarus which averaged less than 20 mpg. Most of my miles are around town, so I am happy with almost 28mpg.

Edit: Just returned from Valencia where I had a Leon 1.2 TSI hire car. I thought someone must have been sneakily filling it whilst I slept because the first tank returned over 620km or ~45mpg. The daft electronic fuel gauge didn't move from full until I hit 180km. You cannot beat analoguye gauges so I am glad Skoda have stuck with them.

Orville, have you tried v power? I was getting same as you at 27/28 now after many of pure tanks of v power with no change in driving it's up at 31/32! I must also add the car runs more smoothly on 99 than standard unleaded just feels a different car when giving it some beans!

Seems like skoda are a lot closer to the claimed mpg than Seat! I am getting a cupra and this has a claimed combined mpg of 44mpg but no one in the Seat forum gets anywhere near this!

I tried V-Power early in the cars life but it made little noticeable difference for me.

 

My results above were from memory and slightly out. My actual average over 11,100 miles is 27.82mpg, best tank was 35mpg dead, and worst 23.78mpg. I have pasted my results below.

 

*Red lines indicate Super Unleaded was used. Within my own VRS it seems to make no difference whatsover.

*Super Unleaded is averaging 27.29mpg after 13x tanks

*Premium Unleaded averages 27.94mpg after 28x tanks

*Best ever and worst ever tanks were on Tesco Premium, so it's how you drive the car rather than which fuel is used.

......I may as well save the money.

 

 

*Average fuel economy improved after the first few months (when I was playing with my new toy and thrashing it about), but has stabilised within the mid-to-late 27's since then.

 

Unless you drive almost ALL motorway miles, within zero traffic, at sub-70mph,  and with a feathered right-foot, 40mpg will remain a pipe-dream for most of us. My hat is off to those who can manage it.

I agree, I get on a chilled out motorway drive 70/80 mph 36/37mpg! I've never seen 40+ so I must have an heavy foot! I'm also told that stop start saves millilitres of fuel per tank! Plus I was always brought up to let a turbocharged petrol engine cool down after a run, surely coming off a good thrashing and having the engine cut straight away at lights isn't good for turbo life? How is the oil still protecting the turbo if it's not being pumped! Stop/start is a no go for me!

No need to let this car idle after a hard slog. The VRS continues running the oil pump for several minutes after the engine is turned off to ensure temps cool down safely, the turbo is protected, and there are no oil hot-spots. You're just wasting fuel (and your own time).

 

I used to religeously allow my Subuar's 5mins to cool-down, but most modern turbo cars have fail-safe timers nowadays,

Really? I never knew that and it's good to know, I too had an impreza sti type ra a few years back and that thing did get warm blimey! I used to have a turbo timer that run for 3 mins then shut down! I had no idea the oil pump still ran without the engine food to know thanks!

It's only money.....

 

How much are going to save every week by buying a diesel?

 

Also, how much would be prepared to pay to drive a nicer car......

 

Our old vRS DSG petrol is averaging 36mpg, & can drop to 45mpg if cruised gently. 

I also find most times after a 150+ mile motorway run, off the M1 and coming into London, stop start won't stop the engine at junctions, not for a good few minutes. Not sure why.

 

I find fuel economy very very closely related to speed.  Sit at 70, not a fraction over, ever, and you'll get 40+, maybe 44.  Go to 75 and sit there and I'll get no more than 38 or 39 mpg
