Skezza Posted August 27, 2013 Report Share Posted August 27, 2013 Hey,So lately, I've turned into a bit of an eco-terrorist... well, car driving wise. I'm trying to get as high MPG as possible out of my SDI Lupo. Someone on here I believe got about 76MPG a few years ago.I was reading various eco modder forums and the Lupo 3L, TDi and SDi are all quite popular cars. Understandable for the 3L of course, but it seems the SDi is the poor mans go for getting good economy. Anyway, I found a thread a few days back by a fella who claimed to get 90MPG out of his SDi. This wasn't a standard SDi... he'd removed the backseats, spare wheel, put low rolling resistance tyres on blown up above the recommended, etc etc etc, so there is no way I was ever going to get that figure. However, I took note of his driving tips for a Lupo SDi and tried to replicate it.First tip was to not go above 2000-2100 revs at all. This is dull driving believe me. You aren't going very fast in fifth (about 55mph in mine) but if you're driving to work on mainly a single carriageway for 35 miles, where 60 is the limit (as I am) then the speed is fine and I don't feel like I'm ever that far behind the person in front. At no point did I feel like I was holding up traffic either. The roads are fairly bendy so I would somewhat argue the speed was appropriate.Second tip was to change up at bang on 2000. Not earlier, and not later.All his other tips were standard hyper-miler tips e.g. avoid stopping if possible (as in keep rolling even at slow pace), etc etc. Which I've been following for a while.Anyway, part way through the week I noticed my fuel consumption was noticeably lower, so I continued to follow his tips by the book. At no point did I go above the recommended 2000-21000 revs. By the time I came to fill up my odometer was reading 483.2 miles which is already high. The tank certainly wasn't empty either.The fill up was 27.67 litres which works out at an astonishing 79.38MPG!I took photos for those who are skeptical, but that said I have nothing to gain by putting the figures up.

Dblock Posted August 27, 2013 Report Share Posted August 27, 2013 Awesome. I've been looking into a 6th gear or a gearbox from a polo blue motion when it comes time to change the clutch. Quote Link to comment Share on other sites More sharing options...
Koop Posted August 27, 2013 Report Share Posted August 27, 2013 I looked into changing 5th on the sport cos it screamed on motorways, as far as I could tell it should be doable without removing the gearbox. Quote Link to comment Share on other sites More sharing options...
Skezza Posted August 27, 2013 Author Report Share Posted August 27, 2013 (edited) Mine is totally standard. It has had some fresh oil lately and a new set of front tyres but other than that I genuinely believe it's all about how you drive. I think it's important to get rid of any extra weight too, without going nuts of course. I'm considering replacing the spare wheel with a can of tyre weld, which is one of the first recommendations on these eco forums.

James827 Posted August 27, 2013 Report Share Posted August 27, 2013 i used to get 79+mpg in my Lupo when i had it, standard engine lowered a bit on 13" wheels with standard tyres.if i ever own one again, il remove the spare wheel and a few other bits. and the seats when im not using them. also i would run the 13" wheels with 155/70 tyres much thinner, much cheaper. less RR which means better fuel consumption. probably windy windows for less weight etc. Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 27, 2013 Report Share Posted August 27, 2013 I looked into changing 5th on the sport cos it screamed on motorways, as far as I could tell it should be doable without removing the gearbox.Saw the 6th gear kit but it was £1k so alot of money. I don't know much a polo gearbox can be picked up for though. Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted August 27, 2013 Report Share Posted August 27, 2013 I struggle to get over 40 in the Sport. Pretty crap reallyVX220 gets 35+! Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 27, 2013 Report Share Posted August 27, 2013 The sport was a really crappy designed car. It was fun and comparatively cheap to insure but the fuel consumption and the amount of problems they have I don't see why anyone would get one. 4k rpm @70 used to get boring quickly aswell.

MarvGTI Posted August 29, 2013 Report Share Posted August 29, 2013 My GTI gets between 25 and 33 mpg.My company car, a smart fortwo cdi (wheezy 800cc 54hp diesel engine) manages about 75mpg.Worst I've had was my Maserati 3200GT (the one with the boomerang rear lights ), 11mpg!!!Marv Quote Link to comment Share on other sites More sharing options...
Skezza Posted August 29, 2013 Author Report Share Posted August 29, 2013 That's pretty impressive from the Smart, but is that a N/A diesel? Surely not, at 800cc it would practically be a no-go? Quote Link to comment Share on other sites More sharing options...
MarvGTI Posted August 29, 2013 Report Share Posted August 29, 2013 Skezza, it's got the teeniest turbocharger you've ever seen it's actually quite torquey, so the lack of power is not apparent until about 65 - 70 mph or when you've got to overtake.Marvin 1 Quote Link to comment Share on other sites More sharing options...
Rich Posted August 29, 2013 Report Share Posted August 29, 2013 I'm tempted to try this SDI economy challenge.I don't think it's anymore economical than the TDI though. Quote Link to comment Share on other sites More sharing options...
Derv Posted August 29, 2013 Report Share Posted August 29, 2013 That is good going in an SDI.Unlike the PD TDIs the SDI can be run on very cheap fuel too, which gives it the potential to be cheaper run than a 3L.As long as you can handle the boredom of driving a NA DERV Quote Link to comment Share on other sites More sharing options...
Skezza Posted August 29, 2013 Author Report Share Posted August 29, 2013 I'm tempted to try this SDI economy challenge.I don't think it's anymore economical than the TDI though.Maybe not, the problem with the TDI is that it's too tempting to boot the turbo. I'm almost certain you could get similar MPG out of a TDI but I'm almost convinced if I owned one, I'd be simply booting the turbo... all the time That is good going in an SDI.Unlike the PD TDIs the SDI can be run on very cheap fuel too, which gives it the potential to be cheaper run than a 3L.As long as you can handle the boredom of driving a NA DERVCorrect. It's not for everyone. Some people hate SDI engines and their lack of performance. I hear from veggie oil forums that the SDI is a perfect car for this. I've looked into it to be honest but veg oil isn't so cheap nowadays. Quote Link to comment Share on other sites More sharing options...
JoeA Posted August 29, 2013 Report Share Posted August 29, 2013 I've looked into it to be honest but veg oil isn't so cheap nowadays.You're not supposed to buy it from ASDA the GVMT put extra tax on anything that can be used as fuel. You best bet is to invest in a filtering system and collect used oil from chippies and pubs etc. Quote Link to comment Share on other sites More sharing options...
Derv Posted August 29, 2013 Report Share Posted August 29, 2013 I am pretty sure that my brother recently got some veg oil for around 70p/litre delivered. He stocks up when he finds a deal.Even running it at 50:50 that would make for pretty cheap motoring in an SDI. Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 29, 2013 Report Share Posted August 29, 2013 Used to run my 106 on svo 100% used to boot or everywhere as it was super slow and super cheap. Quote Link to comment Share on other sites More sharing options...
electricracer Posted August 29, 2013 Report Share Posted August 29, 2013 ok filled my tdi begining of week and been hypermiling best i can, done 250 miles so far and have over half a tank still left, i have cruise so really easy to keep below 2000rpm and cruise at 56mph, did this once before (before cruise fitted) and averaged 86mpg from full tank, but youre right its soooooo tempting to boot it.girlfriends new company car is bmw 116ed thats amazing did 50 mile trip recently of mixed driving and managed 93mpg! ,acording to computer, its fitted with low resistance tyes, start/stop, eco button which alters things like aircon to take less power and be more economical and because of low emmisions its free taxworst car was a subaru impreza ra which me and a friend took to a drift day only used 1st and 2nd gear all day and managed to use a full tank of fuel in less than 70 miles!

Paul Posted August 29, 2013 Report Share Posted August 29, 2013 Good work Skekka On a handful of occasions over the 140,000 miles I've driven my SDi, I've seen 80mpg+ and on the last fill-up I averaged 83.71mpg but that was only over a distance of about 75 miles.At the moment I'm doing about 600 miles between fill-ups so I'm down to about 73-75mpg travelling to and from work on the M42.

Wolf RS Posted August 30, 2013 Report Share Posted August 30, 2013 For the moment in my Lupo 1,4 16V 75hp.I get about 0.57 L/100 km - 495.58 Miles per gallon (UK).Looking to better that. Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 30, 2013 Report Share Posted August 30, 2013 you want to go for 500mpg?Funny thing with these cars is if for example you lost 10% mpg from your flat tyres in a car that does 30mpg it goes down to 27mpg. Worse but still doesn't seem that much. If your doing 60mpg and you lose 10% for example your at 54mpg. Really need to get a scangauge for my car.

I've heard the Scangauge E is the best for casual eco-terrorists but the Scangauge 2 provides **** loads more data. The Scangauge E does have certain features the Scangauge 2 doesn't like real-time graphing etc. I'm always on the lookout for a second hand one as they go for about £60. I reckon it would pay for itself if I followed it closely!! Quote Link to comment Share on other sites More sharing options...
Mini_ash Posted August 30, 2013 Report Share Posted August 30, 2013 i need to start doing this as i am driveing now i am getting 70-75mpg the lowest i have had was around 35mpg car is stock with nothing removed just lowered and wider wheels and a massive subwoofer box in the boot i think the owner has done something to it befor me will not go over 3k in 4th and 5th even going down big hills it hard Quote Link to comment Share on other sites More sharing options...
