IIRC, you only need to replace the chain if it SOUNDS like it needs changing; it's unlikely to 'snap' like a cambelt.

How the hell is everyone getting 40's/mid 40's on their fuel economy?!! My manual '58 plate L&K reularly steadily gets to mid 30's, but it takes a fair old steady run to get it to even crawl over 40 mpg on my maxidot! And I drive like an old biddy most of the time, so how are you lot doing it?!! :doh:

Im into high 30s with mine and on a steady run it will nudge into the low 40s.
I drive it very hard so perhaps you are not driving it fast enough.

Driving slow dosnt always get the best economy. Try driving a bit quiker.

The best "test" I ever had was on a nearly clear part of M25, coming round south-east from the M1 and passing Heathrow.
I was able to cruise on c/control at a steady 58, watching the mpg readout creep up. It got to about 48.9 just before the M3 congestion.
I was trying to get it to 50 mpg - not quite!

On any similar non stop long run at around about 60 m.p.h. it will get into say 44 to 46 m.p.g. but of course nothing like that around town.
When doing similar cruising at the legal - ahem - 70 mph it will just reach very low 40's.

This, by the way, is on bog standard 95, usually Tesco's [discount] due to shopping (miser that I am) but also Esso 95.

+1

Nothing can beat this engine apparently.......apart from everything else above 160bhp! :rofl:


Not all 1.8 TSi's have 160 BHP ;-)

To the OP, it's a very good engine, no problems with it lugging my Superb along behind it, and I tend to drive in a "spirited" fashion. I am averaging around 40 MPG on a run. it's very quiet and rev's to 7k. I have used about 1/2 litre of oil in 19k, most of that within the first 2 - 3k miles after that, nothing, not a drop used.

In summary, smooth, economical and refined with the potential for very good power / torque gains should you remap it.

My 1.8 TSi Superb has done a best of 43.9 MPG on my regular run up to Inverness for work, that's a 420 mile trip at an indicated 80mph and cruise on, last trip I averaged 66mph for the journey and 41mpg.

If they had released the 2.0 TSi before I bought my 1.8 I would "probably" have bought that, but I do love this engine.

Is the 2.0 TSI = Octavia VRS

Or am I totally wrong here ?

oh ok, get ya now : )

But just on the matter, I think the "SE PLUS" Octivia 1.8 tsi has less horse power than the elegance by default.

Fill it with V-Power and stick a pipercross filter in, there's your 8BHP back :-)

Remapping the engines ECU (basically its brain) so that it irons out any flat spots in the power delivery & it can increase torque + fuel economy as well.

Shark performance (sponsor) in Mansfield, Notts do remaps amongst others.

Hmmm, sounds similar if I can do over 20 miles (that's the distance to work and if I pooter to that destination I can sometimes hit the low 40's), just amazed that anyone's consistantly getting mid 40's where I can only do it by trying really hard over 30+ miles! :doh:

I have a 6-7 mile journey into work each day and I can get it to show in 40s regularly & occasionally 50's, but I need to have a very light foot for that.

My journey to work and back is about 25 miles each way and today I got indicated on maxidot 38mpg one way and 43mpg the other - I did see 50mpg at one point. I get around 4 to 5 mpg difference between the 2 journeys quite regularly. The average speed for the journey is normally somewhere between 30 and 35mph and is a mix of urban, rural and 70mph dual carriageway. I have been putting the details in fuelly.com and notice that the economy has been creeping up month by month, 1st month averaged 34.6mpg, last month 38.4mpg and the car has done about 5000 miles now, I wouldn't say I am driving it hard either. I wonder how many miles I need to do before economy settles down. How many miles have you others got on your cars?

Mine's a '58 with about 37k on it and it did get better and better for economy; at first it was only just creeping over into the low 30's, but it's way off what you guys are quoting! I've NEVER seen it get anywhere near 50!! :( There's no way i'd get anywhere near 40mpg after 6 miles, as it starts on about 14 and goes up from there, but it's only in the high 20's/low 30's after that sort of distance. It doesn't rise that quickly, only by jumps of about 0.3 for the first few miles so there's no way mine'd go that high that quickly. :no:

Like I said, I don't exactly cane it, and try to slow naturally as much as possible, so I like to think I drive fairly economically, but i'm just concerned now that either something's wrong with my display or sensor or whatever it is that reads it, my display is actually accurate as i've always heard they're over exagerated (although unlikely), i seem to be the only person in the world who CAN'T drive economically, or that my car has been f*cked from day one. :'(

Just had a look in the brochures I kept from when I bought the car and the urban is 28, extra urban is 47 and combined is 38 (all roughly), so i'm not getting as low as the urban most of the time. Perhaps it's just where i'm driving with more stop starts and not many long motorway runs as even 38 is not unheard of for the roads I tend to drive.

Well I do a mix of normal roads and motorways and to be honest dont check it after a single trip but maybe every 3-4 days.
Ive just checked and on trip 2 the average mpg is showing 38.6 over the last 800 or so miles which I think is ok.
I do drive it hard and I do 2-300 miles a day.

lol @ the mpg figures! I got 34mpg in a 3.6 V8 Jag XJ8 on a 300mile round trip to London yesterday with 5 up. I was also doing the wrong side of 70 all the way there and back on the motorway and spent 1.5 hours in a traffic jam on the way out of London (A40 + rush hour = :( )

It is, I meant the comment of "lol at MPG figures", you driving a filthy diseasel and all that. That V8 is having an easier time of shifting that along at 70+ mph, it's probably just on it's "sweet spot"., or maybe even just off tick over for it :-) Isn't the XJ8 an Aluminium body?
