RedRobin Posted September 4, 2007 Report Share Posted September 4, 2007 ....I'm beginning to wonder if something is either wrong with my mpg display or my actual car - I struggle to see 28 mpg but I do use the gears a lot and I am remapped. I don't cane it everywhere though - Only when appropriate such as overtaking. Okay....I'll admit I quite enjoy roundabouts . I still don't want a stinking diesel.

mikemod Posted September 4, 2007 Report Share Posted September 4, 2007 I think it's probably because your retired so everytime you take your car out you enjoy it. I find my average at the weekend is below 30 but during the week on the trip back and forwards to work I can get high 30's Link to comment Share on other sites More sharing options...
Tarmac_Terrorist Posted September 4, 2007 Report Share Posted September 4, 2007 Agreed - the GTI can achieve MPG in the high 30's easily. Often when on busy A roads you tend to amble along at 50mpg getting amazing mpg. Start to enjoy the car on an open road and the figure can fall into the 20's - as with mpg if many of your journeys are under 10 miles. The mods RR has must have an even greater negative impact on mpg when driving enthusiastically - also getting stuck behind tractors and hanging the car in 2nd gear on those Dorset lanes Link to comment Share on other sites More sharing options...
RedRobin Posted September 4, 2007 Report Share Posted September 4, 2007 I think you guys are right, mikemod and T_T, I hadn't really thought about it that way. Nurmberg to Munich: 90 mph average and 22 mpg and all legal and great fun . Fun around the twisties and fast overtakes on B-roads: Around 26 mpg usually. Cruising on dual carriageways: Around 28 mpg. Consciously reining her in and without enjoyment: Over 30 mpg. I haven't driven since last Friday so I tend to enjoy it when I do go out. Link to comment Share on other sites More sharing options...
Tunner Posted September 4, 2007 Report Share Posted September 4, 2007 I get around 33 mpg which includes cruising at an indicated 85 mph for long periods. The GTI on an open road has amazing MPG considering its performance. Link to comment Share on other sites More sharing options...
PabloPablo Posted September 4, 2007 Report Share Posted September 4, 2007 I average around 35 - 37 during the weekly commute - mostly motorway, so steady 70ish. Having read this thread last weekend, I decided to see just how high I could get it to go IF I drove like a granny on my weekly shopping trip - 12 miles, 80% of which is (quiet) motorway, but from cold. The motorway is a mix of 70, 60 and 50mph limited sections. I kept to 50 - 60 all the way through (hard work!), coasted on a couple of downhill sections (I know, but it's an experiment, right?) and generally tried to plan ahead. This was the result (and no Photochopping, honest!). Link to comment Share on other sites More sharing options...

lensman Posted September 5, 2007 Report Share Posted September 5, 2007 I am really impressed with that, its amazing to think that the best Ive managed in my audi a3 1.8T is about 420miles to a tank(~50 litres = 11 uk gallons), that works out at about 38 MPG !!!! On average I do about 30MPG, thats with a good mixture of a/b roads on the way to work and motorways on the way home, with some traffic on both routes! Goes to show the effect the FSI engine technology has on fuel economy in the mkV GTI! All the better for when I finally pick up my brand new one this saturday Can't frggin wait, Im not one to wish time away, but DAMN! its tough being so close yet so far Just one question are guys using Super unleaded or normal unleaded to acheive these results? Ive heard the FSI system only works at its best when you're using super unleaded (98 RON) ie if I were to use normal unleaded I would be able to get these sorts of figures... Also if I may ask you guys on your opinion on running in a brand new mkV GTI? Do I need to granny it? Any advice much appreciated. all... Link to comment Share on other sites More sharing options...

The TSNer who advocates ragging it is in the motor trade and therefore very experienced. However, he doesn't keep his cars for very long! My advice is to follow the handbook's advice and run her in progressively over the first 1,000 miles. At 39k miles it hasn't done mine any harm. Enjoy!

[/ QUOTE ] It's hard to tell how much of a drop there is, but we're talking slight inclines rather than K2 - the car seems to hold speed pretty well on the flat. And, yes - I did give it some beans on the way back - wouldn't want all those frozen peas defrosting! Link to comment Share on other sites More sharing options...

Jack_is_Back Posted September 5, 2007 Author Report Share Posted September 5, 2007 It says '98' and 'Super Plus Unleaded' inside my fuel cap. It also says (95) with a '!' inside little booklet symbol which I guess means RTFM. IIRC the manual states you should use 98 when possible, but it's okay to run on 95 too.

winrya Posted September 5, 2007 Report Share Posted September 5, 2007 Speaking to someone who knows lots about these engines i was told that you should always run them on 98 super or above. Basically VW have to make it capable of using 95 fuel and thus have to quote performance based on this fuel. I was told you should expect a min of 207-213bhp running on super with good performance gains. Apparently this answers why vw have the 0-60 time at 7.2 but all tests average 60 between 6.5-6.7 secs, and why most rolling road in those guidelines. I'm told its the same with the edition30, s3 and cupra, they all push more than quoted. Also, on super, its more economical, smoother and has less rattle on idle. On a fuel note, ive used optimax/v power since ive owned it and tried some tesco 99 a few weeks back and my god this stuff is superb. I really believe the torque arrives earlier and it runs much more smoothly when cold Link to comment Share on other sites More sharing options...
RedRobin Posted September 5, 2007 Report Share Posted September 5, 2007 In Alaska petrol is only 90 RON in most places . Link to comment Share on other sites More sharing options...
petsy Posted September 5, 2007 Report Share Posted September 5, 2007 using 95 ron means the engine spends less time in stratified mode and it will emit more NOx. the engine is most efficient when using stratified mode and occurs for longer with the higher octane fuel.

Rustynuts Posted September 5, 2007 Report Share Posted September 5, 2007 I never managed to get anywhere near 40mpg from mine. Worst I could manage was 47mpg if I really hammered it. Petrol stinks, btw. Diesel just smells. Link to comment Share on other sites More sharing options...
