Only 500 miles on my 2.0 TSI 220 PS DSG. My daily commute is only 5 miles each way and MPG is currently around 26 in Eco mode.

Should I expect improvement after run-in?

Has anyone achieved better MPG by changing gears manually?

My work run is about 3 miles. On the way in I keep her in manual mode mainly so I can have her upto temp properly before I get their.

Takes about 15 mins to get the oil to 90degC, below which I always keep revs low

Nick, what is the oil temperature showing when you get to work?

Depends on the ambient but I'm happy if it's 90+. This morning it was 97.

How's this for a 1.4act manual, Amesbury to Staines, 65 steady miles with about 12 miles of 50mph road works. Car set in eco mode.

 

 

Impressive - better save my pennies ready for an 1.4ACT

 

My best ever tankful-tankful average on the MKII 1.4 tsi was 53mpg

 

What's the 1.4 ACT like at warming up? My mkII takes quite a few miles and during that period it's not so economical. Your 1.4 is a totally re-designed engine that is supposed to be better at this

Not near your best tank to tank figure yet as only on my fourth fuel up as to get the above figure needs an uninterrupted run with limited in town driving.

In saying that, it warms up within say five minutes, ACT won't kick on during the first few minutes running but thereafter it's away. Still learning how best to use it. At low revs in high gear ACT won't kick in presumably because engine will become unacceptably lumpy, so dropping a cog to maintain a higher engine speed will induce ACT and return a lower fuel consumption.

It really is an excellent powertrain and I'm happy with choice of a manual despite coming from an auto. For most of the time there is more than sufficient power, sure you can't do spur of the moment overtakes in the way that you can do with a torquey diesel or 200bhp+ petrol turbo, but to me it seems a less stressful way to travel and more involving as you have to plan ahead that bit more.

Highly recommended!

As I said above, I'm still waiting for delivery of my 2.0 TSI (220 DSG). With that in mind I'm only regurgitating what I've read before on this forum, but since nobody else has mentioned it... Have another go with normal mode instead of eco. Several people have reported that eco mode actually ends up costing them fuel, perhaps the loss of fuel cut off on over-run?

Do you mean that automatic coasting in Eco actually can consume more fuel than when the car is left in gear?

Any recent (~20 years or so) fuel injected car will use no fuel at all on over-run. So if you're doing 60mph up a hill then take your foot off at the top, you'll use zero fuel all the way down the hill. That's just one example, not a specific proviso.

 

In eco mode, the gearbox disengages the clutches to eliminate engine retardation ('engine braking'), which will get you further along the road before a gear is selected (compared to just taking your foot off the accelerator while remaining in-gear). Coasting will however use as much fuel as is required to keep the engine idling at tickover speeds. In some circumstances the trade off is worth it, in others you'll use more fuel idling than you saved by 'making more progress' due to the lack of retardation. As I said, I've not tried it on the Superb 220 yet but that's how all engines work and I've seen it reported several times on here (and in reviews) that normal mode actually produced better MPG than 'eco' mode.

Thank you for the explanation. You've answered the question that I posted in another thread.

No worries. Perhaps a better way to put it (the curse of rushed posting!) is that by lifting off the 'gas' while staying in gear you are allowing the wheels to turn the engine, which means it needs no fuel to 'keep going'. This is why you slow down quicker than with coasting - the effort of the wheels turning the engine over is what loses you momentum faster. Conversely if you disengage the clutch(es), you remove the drive of the wheels to the engine, hence it needs fuel to keep on moving until you want to use it again but you will move a lot further down the road before 'running out of revs', as the wheels are not losing speed (energy) due to having to power the engine as well as moving around and around down the road. I hope that makes sense mate.

That's quite hot for the time of year & your short commute.

 

I'm on jury service ATM so I have a regular 13 mile trip & the EOS isn't quite making it to 90 when I park-up.

 

It's mostly on NSL roads after the 1'st mile or so, so I'm cruising at 2K'ish  rpm, so the engine isn't working hard.

I used the Superb for the same journey last week & that does warm up earlier, but it is much lower geared than the VW,

(2K rpm in the EOS = 63 mph, but app. 51mph in the Superb.)

Yes I'm amazed how quickly it warms up. And thats treating a cold engine carefully. I probably don't go any higher than third gear but keep the revs below 3k. Never had s motor warm up so quickly.

Oil temperature was 80 at the end of my 5-mile drive to work this morning. I switched it from Eco to Normal and MPG has increased very slightly to 26.9.

Engine start 9am. Outside temp 8'. Coolant upto running temp at 9:08. Pull up at work at 9:27. Distance travelled 3.6 miles. Oil temp 100 just as I pull Ip.

Ah, well if I was in the dock (but innocent!) I'd be glad to have someone of such good judgement to own a Superb in the jury ;-)

Not so good yesterday, left Heathrow at 9pm back to West Wales as quickly as was safely possible. 43.8 door to door, but the last 20 miles I was comparing the cross country handling to the Leon and involved lots of WOT application!

It's crying out for another 100Nm of torque and the corresponding horses that would accompany such a change [emoji4]

Quite so..........., 

 

However, I'm thinking of having a Mustang test-drive next sometime week, & that might not be construed 

as good judgement at all!

 

Superb 280 or Mustang Coupe, sensible or stupid?

Not sure on the 'Stangs looks.... Nothing like a V8 though ....

I used the EOS to get to court this AM, 15 mile trip, 24 minutes, but it took 4 miles for the oil temp. to reach 50C.

 

It's not an urban drive, 1/2 mile 30 limit, 1 mile 40 limit spine road through the town then 60 limit, (45-50 mph traffic) for 2 1/2 miles then

dual carriageways all the way except the last 1/2 mile. App. 95C when I got to the car-park.

 

The normal driving time is app. 26 mins, but I was in a hurry, & the EOS seems to be quite nippy.....

About 33 mpg this AM, but 36 mpg in SWMBO's vRS yesterday.

I'll probably use the Superb next week, it'll be interesting to see  if it's very different.

 

As for engine speeds, usually in "D", up-shifting at 2- 2.5K rpm, & not exceeding 3K rpms.

It looks like a Mustang & the RHD interior looks kosher

It's 2080 mm wide over the mirrors & that be problem on some roads.

It has quite a low roof line, meaning that some people will have to sit quite low to see through the windscreen

& the really long bonnet just might be a problem in UK car parks.

 

Watch this space............

Do it... Nice bright colour :-)

Yeah, you've got to have fun!

Back on topic, the first week of the car which included a 2hr motorway journey to London and then a whole load of stuff around town (quite a lot of traffic and sitting in the eerie silence!) totalled 300 miles and consumed 31 litres of fuel, so about 43mpg or 10.5p/mile. I'm pretty happy with that given the circumstances. Suspect previous car would have been somewhere in the 25-30 range (but a Volvo C70 2.0t convertible is not designed for that!). If diesel prices stay at this level, I suppose I'm looking at £1,000/year in fuel costs.

I'm usually pretty cynical about this sort of thing but I've noticed that my 150 tdi seems to be returning about 4 or 5 mpg more on bog standard Esso diesel compared to the Tesco equivalent (after two tanks of each, alternating). I've just filled up with Shell diesel and I'm getting consumption figures closer to the Tesco fuel.

Overall, I'm getting anything between about 40 mpg on my 5 mile commute to 63 mpg on a long motorway run at 65 mph. Long term average currently at 48 mpg after 2.5k miles.
