Most cost effeciant way to drive…
the one that allows you to drive at 50mph, steadily, with no stopping, roundabouts, and not too many gear chnges.
i find b roads more efficient, as i get stuck behind stuff to chug along at 50 happily listening to teh radio, and getting 60mpg
if im on a clear motorway, before i know it im doing 85 and getting 40mpg.Posted 8 years agoowenfackrellMember
It is constant speed that is the best way.Posted 8 years ago
if you drive at a steady 70 on the motorway then you will fair better interms of mpg than driveing on a hilly route where you have to use more of the accelerater pedal in order to get up the hills.
As for your route it will depend on the difference in the distance as to which is cheaper.Forking Our SoulsMember
Sit behind a lorry on the motorway. I can get 30% better MPG doing that – I've got a thirsty car and often find myself on empty on the motorway.
You don't have to get close either – the optimum point is the back end of their turbulence which is a perfectly safe distance.Posted 8 years agoxc-steveMember
Right this weekend I'm visiting friends in Surrey, now google maps is suggesting 3 roots:
I'm more inclined to take the M4 rout since it'll be an easier drive and I can just stay in the middle lane and not use my mirrors (jokes).
However which will be do less damage to my petrol tank? The physically shorter rout with more hills and gear changes or the longer rout of constant speed? Is this a catch 22 situation or is the M5/M4 the obvious choice?Posted 8 years agoslugwashMember
I do Totnes to Central London and back several times a year and the A38/A303/M3 route is much less harsh on petrol costs compared with the motorway nearly all the way option. It's shorter, keeps your average speed down and takes about the same time. I also find that the A303 option prevents my missus from filling up the car with crap from the Bristol Ikea, which can make the motorway route more expensive as well 😉Posted 8 years agomolgripsSubscriber
I can get 70mpg on A roads if I try, but only 50 on the motorway*.
As an owner of a car that gives you a comprehensive MPG breakdown at all times, I can say that the best for MPG is wide open A roads with few hills. As they get hillier/more windy they drop to being less economical than a 70mph motorway run.
Having said that I once got 78mpg from my sister's house to my Mum's, cos it was on empty A roads basically up a short steep hill then a very long gentle coast down the other side. So certain hills are better than others 🙂Posted 8 years agothisisnotaspoonMember
depends on the value of your time as well surely?
If its on a weekday, would you be better off working some overtime then driving faster or finishing on the dot and driving slower?
eg, if costs £10 extra to do the journey in the fast lane, but takes an hour off the journey, and your boss pays you £10 after tax then youd break even and be in your boss' good books (assuming he wants to pay you overtime).Posted 8 years ago
