FalconFN Posted February 20, 2016 Report Share Posted February 20, 2016 Seriously ? The mpg gain would be so small you would need a lab to test it. Keep speed down (50 ish) try not to brake then accelerate, try to keep rolling along. Other than that buy a smaller car. What vehicle and what mpg? +1 Quote Link to comment Share on other sites More sharing options...

Gordon R Posted February 20, 2016 Report Share Posted February 20, 2016 I love people who stick in a couple of shorter springs and think that is it. It alters the geometry of your suspension and might be better on MPG or it might be far worse. It will increase your insurance for starters. If you don't tell them and you are ever involved in a serious accident - they will disown you. That would have repercussions on your SGC.

shoot and be safe Posted February 20, 2016 Report Share Posted February 20, 2016 Buy a bike for motorway driving cheers for thatAlways a pleasure my good man You could always try public transport Not knowing what vehicle you are running to improve the mpg on I couldn't comment on how to improve, however a less heavy right foot may help.

BrowningB525 Posted February 21, 2016 Report Share Posted February 21, 2016 Ok seriously now im not talking about the tyres rubbing on the arches or anything but the bluemotion vars are slightly lowered arent they so i was wondering if it would help a set of springs is like 50 quid and i do alot of motorway driving. My tyres are fully inflated and i regularly service the car what else can i do You can get the ecu remapped for fuel efficiency. Lowering won't really make a difference. You'd get more from reducing weight. Quote Link to comment Share on other sites More sharing options...

Other than that: dingle-balls, furry dice, go faster stripes, or, or, or those spacers that push your wheels out another inch or so. Quote Link to comment Share on other sites More sharing options...

Gordon R Posted February 21, 2016 Report Share Posted February 21, 2016 In the 1970s, I fitted a vacuum gauge to a Morris 1800 - best fuel saver ever. It taught me to drive more economically - easing back on the pedal whilst maintaining the same speed. As someone else has said - teach your right foot not to be too heavy, plan your route for economy, don't make unnecessary journeys - or put your foot down and to hell with economy.

rodp Posted February 21, 2016 Report Share Posted February 21, 2016 If you'd driven an old artic with 32t powered by a Gardener 180 you'd know all about driving to the road and keeping it moving :lol: Quote Link to comment Share on other sites More sharing options...
figgy Posted February 21, 2016 Report Share Posted February 21, 2016 No you won't save any fuel by lowering it. It's not going to change the drag co efficient enough. Turning off heated rear window demist air con and other non essential electrical gubbins making sure windows are up will improve mpg by cutting the load on the alternator. If your that bothered by the mpg buy a newer smaller bodied and smaller engined car. Quote Link to comment Share on other sites More sharing options...

TIGHTCHOKE Posted February 21, 2016 Report Share Posted February 21, 2016 A light right foot, air conditioning off, windows up, clean car, tyres correctly inflated and being in the correct gear will all help to get the most out of your tank of fuel.

mattyg1086 Posted February 22, 2016 Author Report Share Posted February 22, 2016 (edited) Ive got a vectra 1.9 cdti 150 auto. I am not a boy racer and never have been im young ish but ive got a family so not particularly interested in racing about. My average over the last 50k is 46 mpg lowering was just a thought as the bluemotion cars are lower im thinking about having it remapped but im undecided whether or not id make the money back. If i can get it up to say 50-55 mpg average i may be able to buy another car a small 4x4 or a new sg the cheaper i can get to work the better as it means more money in my pocket obviously i cant get a diesel citroen c1 and get 80 mpg as i need the space of a vectra sized car to take the kids and dog out in also a c1 on the motorway im not sure would be the safest thing Edited February 22, 2016 by mattyg1086 Quote Link to comment Share on other sites More sharing options...
rjimmer Posted February 22, 2016 Report Share Posted February 22, 2016 Keep speed down (50 ish) try not to brake then accelerate, try to keep rolling along. Other than that buy a smaller car. Perhaps I'm imaging it but, on a long run, I think I get more mpg from my 1.4 Polo after it starts warm, say after calling at a service stop for a few minutes. The electronics have had time to discharge, but the engine is still warm. Quote Link to comment Share on other sites More sharing options...
Cosd Posted February 22, 2016 Report Share Posted February 22, 2016 and a "Turbo" or "GTI" badge Though this does work to a degree, you really need to look at the latest technology to maximise the results. If you add a "Hybrid" badge to the rear of the car, it will not only improve the efficiency, but you also pay less road tax! Quote Link to comment Share on other sites More sharing options...

TONY R Posted March 5, 2016 Report Share Posted March 5, 2016 (edited) Chip it. Zero experiernce with them but some say they work , . BUT ME being the etternal sceptic and all that. Weight loose it just add lightness anything you dont need take it off, and glass is super heavy swap it for perspex , heaters seats boots clothes its endless, and dont forget the drill drill everything holes weigh nothing tool station hole cutters are your friend.
