marzman Posted March 30, 2011 Posted March 30, 2011 I had to drive up to Durham today to meet some clients, which was a bit of a trek...! So i set off with the intention of driving as economically as i could... i.e. not using my brakes, not revving past 3k revs etc... i kept at a constant speed of 70mph most of the way, dropping down to 50mph for about 20 miles due to roadworks/average speed cameras... and i managed to get home with a reading of 34.97 MPG... Im very happy with that. Just thought i'd share.. Quote
Sam Mcgoo Posted March 30, 2011 Posted March 30, 2011 Good effort! But did you enjoy the drive? Quote
marzman Posted March 30, 2011 Author Posted March 30, 2011 Yep it was just as fun... it was all on the motorway anyway so it was absolutely no difference, accept that as im going a bit slower i now have time to notice everyone turning and staring at my car... Quote
liam42whu Posted March 30, 2011 Posted March 30, 2011 As my gf would say theres nufin gay about saving the polar bears Quote
spursmaddave Posted March 30, 2011 Posted March 30, 2011 To be honest to drive 350 miles on motorways and get less than around 28-30mpg you would have to be driving like a nob Quote
Lexx Posted March 30, 2011 Posted March 30, 2011 Shame you couldnt hang around. Durham is a fantastic city, I wouldd have came through and showed you the sites (bars) lol Quote
un1eash Posted March 30, 2011 Posted March 30, 2011 I did 35mpg on the way to JAE last year from Leicester. Quote
LRF4N Posted March 30, 2011 Posted March 30, 2011 I got 34 on my way home from picking it up. That was me having fun and cruising- u shoulda been pushing 40 Quote

HEADPHONES Posted March 30, 2011 Posted March 30, 2011 This reminds me of the petrol crisis around 10 yrs ago when pumps ran dry and the roads were like a scene from MadMax. I remember trying to coast the last two bends to my driveway to the extent I barely needed to touch the brakes as I parked up Fun challenge at first, but required soooo much concentration and planning to not hit a red light or have to brake too suddenly. Kinda like planning out a big snooker break.......hope we never face that again Quote
rabbitstew Posted March 30, 2011 Posted March 30, 2011 Awesome! Not sure I could hit that sort of mpg tho, even if i tried. I could regularly hit 60->70mpg in my golf tdi, but the same driving in the 350z is currently hitting 26. Must try harder! Quote
elfman Posted March 31, 2011 Posted March 31, 2011 i did a few weeks experiment to see what kinda mpg i could get out of the zed, stuck the throttle control on eco5, never went about 2-2.5k rpm rarely used over 15-20% throttle, tried to not stop at lights etc, could average 33 on back roads 30 in town and if you stik to 60mph on motorways you get gat 36 or so if your good enough. but hell it got boring after a while! ok when the weather is shocking though. saying that did 20 miles back roads the other day, not ragging it all the time and got around 25 mpg, stuck it at 70 for 40 mile of motorway and it was soon up to 31+ Quote
dangerman Posted March 31, 2011 Posted March 31, 2011 At lunch time yesterday I went into the car park for a snooze. Felt a bit nippy. Turned on the engine to keep toasty. 25 minutes later I had noticed my mpg had gone from 22.2 to 21.9 by just idling away! Quote
elfman Posted March 31, 2011 Posted March 31, 2011 your using petrol, but not moving... kinda self explanatory imo Quote
dangerman Posted March 31, 2011 Posted March 31, 2011 Why at a consistent idle would the rate of petrol being consumed increase? Not really that self explanatory methinks... Quote
Chris`I Posted March 31, 2011 Posted March 31, 2011 Why at a consistent idle would the rate of petrol being consumed increase? Not really that self explanatory methinks... Because as the car sees it, the milage you have done for the current fuel usage is on average dropping. All it does is divide the number of miles you have done by the petrol you have used, use petrol without going anywhere and the average will drop Quote
dangerman Posted March 31, 2011 Posted March 31, 2011 Wow I really thought it was more sophisticated than that! Quote
elfman Posted March 31, 2011 Posted March 31, 2011 Well explained chris. Another thing i found supprising is you use more fuel in neutral so if your coming up to a junction keep it in gear and dont just coast up Most people probs knew that but still Quote
Chris`I Posted March 31, 2011 Posted March 31, 2011 Another thing i found supprising is you use more fuel in neutral so if your coming up to a junction keep it in gear and dont just coast up Again, not when you think about it When coasting, the engine has to keep itself idling/spinning which means it uses a certain amount of fuel to keep the engine, flywheel and other running gear turning. When keeping it in gear and under no load, road speed is spinning the engine, and the ECU knows this, so it cuts all but the bare minimum of fuel from the engine (infact I think these days it does actually cut all fuel) meaning it uses next to sod all if any fuel until you put the engine under load again. Been like that for a good few years now EDIT: Hang on think I might have misread that. Are you talking about coasting in gear vs out of gear or constantly coming to stop and starting again vs slowly crawling all the way? Quote
elfman Posted March 31, 2011 Posted March 31, 2011 exactly what i'm talking about, leave a gap, leave the car in gear as neutral uses more fuel Quote
