grazo22 Posted January 4, 2011 Report Share Posted January 4, 2011 OlaI've had a read around for posts on this and I'm starting to get more and more worried about my broom broom.Consistently I am getting around 36 mpg from my sport. I bought this car thinking it would be far far better than my land rover but is basically pushing 4 mpg more for just over half the defenders engine size.I did read around quite a bit before I bought my lupe and was hoping to get 45 mpg as my commute is 15 miles of varied driving. There is a small section of duel carriage way 2 miles long and about 60 mph normally, the rest it a trundle along an a road at 40 and a few sets of lights. I've been using spiritmonitor OWL THE LUPOS FUELI've just changed the plugs, cleaned out the throttle body, just about to change all filters and all the tyre pressure are correct. I change at 2000 if at all possible so what on earth is wrong.I generally see how many miles to do per quarter tank and it's normally about 70 max but sometimes drops to 60 or less :SSorry for long boring postThanks in advance chaps for saving my fuel.

Bickerton Posted January 4, 2011 Report Share Posted January 4, 2011 I get about 230-250 a tank from my 1.4Depends what kinda driver you are and what kinda route you take Quote Link to comment Share on other sites More sharing options...
treblet Posted January 4, 2011 Report Share Posted January 4, 2011 Air temperature, tyre inflation, condition of service and engine all have effects on fuel economy.You'll get more MPG in the summer as the air is thinner due to the heat and therefore needs less fuel to burn, cold winter air has opposite effects.

grazo22 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Engine is in good condition certainly, only done 65,000 miles and has a full service history, I know the air does take a toll but not so great that driving like a slow old granny would still get me awful mpg Quote Link to comment Share on other sites More sharing options...
treblet Posted January 4, 2011 Report Share Posted January 4, 2011 You drive a sport too, renound for being thirsty and uneconomical. Quote Link to comment Share on other sites More sharing options...
grazo22 Posted January 4, 2011 Author Report Share Posted January 4, 2011 I know they aren't suppose to be good by any means and wasn't expecting something amazing but 36mpg at best just can't be right. I'm the most un-economical sport on spirit monitor Quote Link to comment Share on other sites More sharing options...
treblet Posted January 4, 2011 Report Share Posted January 4, 2011 What are your tyre pressures like?Are you carrying any excess weight around?What is your driving style?Short or long trips? Quote Link to comment Share on other sites More sharing options...
grazo22 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Pressures all as per the book. No excess wait at all other than my cuppa.I drive in a massively fuel saving style changing at 2000 rpm and not accelerating fast at allI commute 15 miles each way each day which is an extremely economical route.I just can't work out why I do everything to get the best mpg possible and I such an awful returnMy mums cooper s is getting the same mpg :/ Quote Link to comment Share on other sites More sharing options...
treblet Posted January 4, 2011 Report Share Posted January 4, 2011 I did read above that you have a few sets of traffic lights, the stop-start driving will effect your MPG Quote Link to comment Share on other sites More sharing options...
Dannyshack Posted January 4, 2011 Report Share Posted January 4, 2011 im worrying too, its happening to me, i have a lupo 1.0, it used to do 200 miles on 20quid now its only doing 130-140 max doing same route etc to college. I drive it completely the same, its only done 19,000 miles so engine is in good condition and has new tyres on.. Quote Link to comment Share on other sites More sharing options...

If fuel was cheaper I could get 300 miles to £20 but that'll never happen! Quote Link to comment Share on other sites More sharing options...
grazo22 Posted January 4, 2011 Author Report Share Posted January 4, 2011 seriously though, these traffic lights are like a 10 second wait if they aren't green. There must be some kind of mechanical problem causing this was my thought Quote Link to comment Share on other sites More sharing options...

treblet Posted January 4, 2011 Report Share Posted January 4, 2011 It's not the fact you're stopped that's costing you in fuel, you could idle there for hours if you wanted.The economy hit comes from getting the car moving again, which is why you get better economy on long motorway drives rather than nipping to the shops.

grazo22 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Can't make than much of a difference though, same journey in my landy did 32 mpg similar speeds. Motorway journeys at 60 though I get the same mpg.I've taken this eco driving so far, I drive so slowly I probably haven't stopped at lights for days because I time it.There are quite a few sports over 40 mpg easily from what I've seen Quote Link to comment Share on other sites More sharing options...
Bickerton Posted January 4, 2011 Report Share Posted January 4, 2011 Landy engine needs to work less thought, my mate gets about 4mpg less than my lupo on average in his E36 328i Quote Link to comment Share on other sites More sharing options...
jamiea7x Posted January 4, 2011 Report Share Posted January 4, 2011 on a run my sport gets around the 41-45 mark but normal driving i get around mid to high 30's sports are just thirsty little cars, do you run it on super? if not that might contribute as to why aswell. sports are mapped to run on higher octane fuels such as v power Quote Link to comment Share on other sites More sharing options...

I know landy does need to do less work but RPM wise in the landy I'm doing 2500 rpm at 50 which is pretty much the same as the lupo.on a run my sport gets around the 41-45 mark but normal driving i get around mid to high 30's sports are just thirsty little cars, do you run it on super? if not that might contribute as to why aswell. sports are mapped to run on higher octane fuels such as v powerNo I don't, I use do normal fuel at the moment. I did wonder this, although using a lower octane fuel shouldn't affect my consumption, only my power. On the fuel filler cap it says 95 ocatane, which is what I use, always shell.Octane is only a tendency for the engine to knock and would only be a benefit in high compression engines. From my chemistry A level this is what I understand :SI might give it a go though next time I fill up Quote Link to comment Share on other sites More sharing options...
RobG Posted January 5, 2011 Report Share Posted January 5, 2011 I get similar mpg in my sport, running on either tesco super or vpower, most recently it's been vpower just to see if i get less black crap over the back end. My trips are all fairly short though, very rarely get out of the county, mostly just visiting sites for work. Interestingly the most economical it has ever been was when grannying it down to my mum's (about 180 miles mway) and it got 47.6. Conversely one trip up to a meet at Baltic where i was caning it, i got 45mpg. Go figure. Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted January 5, 2011 Report Share Posted January 5, 2011 PI drive in a massively fuel saving style changing at 2000 rpm and not accelerating fast at allIts not a diesel, change at higher RPM, it will be labouring all the time if you are changing up at 2k!

marcusgrant Posted January 5, 2011 Report Share Posted January 5, 2011 36 mpg seems fair to me...i think i got a little bit less than that but all my driving was mainly through town and country roads Quote Link to comment Share on other sites More sharing options...

Go figure.This is the kind of MPG I would love to get because my normal driving is quite a good run of steady drivingIts not a diesel, change at higher RPM, it will be labouring all the time if you are changing up at 2k!I only change at 2000 if I'm on a flat and accelerating seriously slowly. Pushing it past 3000 though can't do anything but drink fuel though. In Owls manual it says change at 2000rpm for optimum efficiency.I just don't understand why VW would post these figures out, of of them being over 50 mpg, if there was no realistic chance of reaching them. Every other car I have ever driven I have always been able to far out do the combined cycle figure :S Quote Link to comment Share on other sites More sharing options...
saq85 Posted January 5, 2011 Report Share Posted January 5, 2011 i get really **** mpg, like 150 on a fulltank, gti. short 5mile trips to work. *shrugs* Quote Link to comment Share on other sites More sharing options...

elajf1 Posted January 7, 2011 Report Share Posted January 7, 2011 Our sport used to get around 44mpg consistantly when our previous jobs involved a motorway/A road run each day. Now my wife just uses it for a a hilly B road 20 min drive to work and fuel consumption has dropped dramatically. I reckon I now get 230-250 from a tank as opposed to 270-300 on a long run before. As mentioned before it is all down to air temp, road conditions, tyre pressure/condition, servicing and definitely fuel. 97ron does give me more MPG from the tests I have done at home. Incidently I usually change around 3500-4000rpmAdrian. Quote Link to comment Share on other sites More sharing options...
