rayaans Posted December 14, 2015 Share Posted December 14, 2015 It was at 36mpg before we came up the hill - it dropped to 32mpg at that point. Quote Link to comment Share on other sites More sharing options...
wh05apk Posted December 14, 2015 Share Posted December 14, 2015 Must have been one hell of a hill to knock it down by 4 mpg after 12 miles, where was the hill? Everest?! Quote Link to comment Share on other sites More sharing options...
rayaans Posted December 15, 2015 Share Posted December 15, 2015 Must have been one hell of a hill to knock it down by 4 mpg after 12 miles, where was the hill? Everest?! Hill near batley on Halifax road. Its only a 2 mile stretch but the problem is it has speed cameras so you need to slow down and accelerate again when going upwards!

Slickk Posted December 15, 2015 Share Posted December 15, 2015 Must have been one hell of a hill to knock it down by 4 mpg after 12 miles, where was the hill? Everest?! Hill near batley on Halifax road. Its only a 2 mile stretch but the problem is it has speed cameras so you need to slow down and accelerate again when going upwards! I find Healey Lane to be damaging for 2 reasons. Firstly, as that particular road is need of repair and has been like that for a few years now. I always slow down, often quite drastically to avoid the various potholes - which results in a relatively short, but slightly embarrassing tailback behind my car. Secondly, irrespective of applying the appropriate amount of throttle, the car doesn't really have a sense of urgency to tackle the ascent. Obviously, I'm not complaining due to the state of the road, but I wouldn't want to drive up there any quicker than 10-15 mph if that.

Rabbers Posted December 17, 2015 Share Posted December 17, 2015 Unless you want to analyse your consumption in detail, or your driving mix and conditions vary a lot from one tankful to the next, you can get a convenient and accurate indication of how economically (or not) you are driving from the range distance figure shown on the multi-information display immediately after refueling to the brim. This tells you, based on your average consumption, how far you can expect the next 56 litres (=12.3 gals) to take you before the low-fuel warning comes on leaving you with 10 litres (=2.2 gals) or so still in the tank. Just how satisfactory the range may be depends entirely on you and your style of driving. As for me, I am disappointed nowadays if I see less than 950km (=590 miles), which would mean that I have been achieving worse than 17km/l (=48mpg). However, when I remember that I was customarily seeing a figure closer to 800km (=500 miles) for a consumption of about 14km/l (=40mpg), or worse, when I first had the car, I am today well enough pleased to think that I have learned to drive it more efficiently than I formerly did.

Aztectt2000 Posted December 22, 2015 Share Posted December 22, 2015 Since owning my car (4ish weeks) I've only reset the mpg readout twice and can report an average of 47mpg over my weekly commute which consists of 3x160 mile round trips on the motorway and maybe 20 miles in town driving. My main concern when purchasing was that I'd see significantly less mpg on the motorway vs my 3series, but I'm glad to say that I'm only down by around 6mpg overall. 2015 IS300h Exec edition Quote Link to comment Share on other sites More sharing options...
darrude Posted December 22, 2015 Share Posted December 22, 2015 Similar commute to me, and I'm currently getting 47, in summer it was 53ish so hourly you will get your 6 mpgs back... Quote Link to comment Share on other sites More sharing options...
Aztectt2000 Posted December 22, 2015 Share Posted December 22, 2015 I'm definitely happy with it but as others have said, my driving style has changed somewhat. I was following a colleague down the motorway yesterday behind his 2013 3series and I just didn't fancy keeping up and instead sat at 75 while he disappeared into the distance.

rayaans Posted February 6, 2016 Share Posted February 6, 2016 Bit of a thread revival but this what I managed to get after 40 miles or so. Pretty impressed although I was stuck in traffic for about 10 miles lol Quote Link to comment Share on other sites More sharing options...
Sajid786 Posted February 26, 2016 Share Posted February 26, 2016 I have 120 miles daily commute M60 and M6 my 2015 IS300H averages 49, best I had is 61. May improve in summer Quote Link to comment Share on other sites More sharing options...
BigChange Posted April 10, 2016 Share Posted April 10, 2016 Service guy surprised me during discussion on my disappointing mpg by suggesting it would improve by using Sport for Mway and speedy country driving, Eco in town and Normal for the rest. Sounded bit counter-intuitive to me as I tend to use Eco on the mway, Normal for the rest and hardly ever use Sport. I'm sure the forum will have some advice !

Roscobbc Posted April 13, 2016 Share Posted April 13, 2016 Interesting comment re. improving fuel consumption. I had had IS300H for 18 months and now at 38000 miles. Living on the outskirts of London most of my driving is outer London, M25 and inner London. Fuel economy seems to average between 43 - 45 mpg at best. Yes, a leisurely (if that is the right word) amble around the M25 at 55 -60 mph will see average economy creep up to high 40's, even low 50's. Kinda have the feeling that a longer motorway journey at these speeds would creep up to higher 50's - no more. My Sunday trip earlier this week up to Birmingham and back netted 46 mpg (at legal speeds) So today on a regular trip down to our works on the East Sussex coast comprises 10 miles of 50 mph 'B' roads, 35 miles of M25/A21 'A' road and then a further 20 miles of mixed 50/60 'A' road. I usually get 44 - 47 mpg on this trip. Today I did the run down (and return journey) in 'Sport' mode rather than the usual standard or Eco. Trip down read 48.1 mpg average. Return trip was a little slower and hence clocked 49.1 mpg. Obviously the car responded far more lively although I didn't take advantage of this - quite the opposite. The thing that was noticeable was that usually when changing from 50 mph 'A' roads to 70 mph 'A' roads and motorways the fuel consumption usually starts to drop a little. In 'Sport' mode it was starting to increase at 70 -75 mph. Even more significant was that at the end of my return journey in sub 30 mph traffic the average mpg was improving further and had I driven another 3 or 4 miles I'm sure it would have gone over 50 mpg average. Perhaps part of my 'perception' is down to the fact that mpg recorded is 'average' and not 'instant' mpg. Irrespectively it seems as though I have seen a 'real' 2-3 mpg benefit in 'Sport' mode today Quote Link to comment Share on other sites More sharing options...
Steve44 Posted April 13, 2016 Share Posted April 13, 2016 Interesting, my experience of sport mode is a 2 to 3 mpg reduction in mpg, though this is usually accompanied by spirited driving. Did you use cruise control to mange the speed? The throttle is so twitchy in Sport it makes it hard to maintain a constant speed on the motorway manually. Will give this a go next time too.

tHomBleached Posted April 14, 2016 Share Posted April 14, 2016 I've mentioned this on another thread, but I recently undertook a long drive from Burton through to Paris and back. I found eco mode a tad counter-intuitive on motorways as to get good economy you should really be getting up to speed as quickly as possible - the long drawn out revs using eco means the engine's working harder to get up to speed. Once you're at speed it really doesn't matter if you're in eco/normal/sport. For me eco makes sense around town as the low speeds don't need a quick change in speed or any really maintenance of speed as it's so changeable around town With a bit of playing about I find the following to get the best performance: Town - eco Motorway - sport into sliproads, normal at roundabouts and cruising. With a fully packed car and 5 people I averaged 50MPG in the UK and 45MPG in France (most M-ways are 130km/hr limit; which I made use of) Quote Link to comment Share on other sites More sharing options...
Gearoidmuar Posted May 27, 2016 Share Posted May 27, 2016 My car's done about 3500 in five months or so. Recently the MPG's got better, warmer weather maybe and being run-in. Anyway on trip to Mayo and back (400m) averaged 55.9 mpg. Only about 20m on motorway. Rest on dual and single carriageway roads. Last week drove to Dublin hard (90% motorway). Averaged 49mpg. Back from Dublin today. Was tired so stuck at 62mph rather than 75. I was amazed, 58.8 MPG. I think that's extraordinary. I just love everything about this car except that it doesn't have automatic wipers. Quote Link to comment Share on other sites More sharing options...
MarksaCox Posted May 28, 2016 Share Posted May 28, 2016 Auto Wipers. I thought they all have it. Have you the button on the end of the wiper stalk pressed? It will have a small green light when activated! Sent from my Iphone using Lexus OC Quote Link to comment Share on other sites More sharing options...

My overall was 46.8 ...... Not bad for a 250? According to the computer, I average 45 mpg. But, mpg aside here, how do I get the sat nav to change it's colours to night mode as in the picture above? The Mrs. changed it to day mode permanently (somehow) and it's not to my preference during night driving. Quote Link to comment Share on other sites More sharing options...

RichyRich Posted June 1, 2016 Share Posted June 1, 2016 Glad to see MPG is likely to increase over my 220D in the 300H. Will bare in mind the use of sport on motorways and eco in town. Will report on mine once it arrives in a few weeks :) Quote Link to comment Share on other sites More sharing options...
Gearoidmuar Posted June 2, 2016 Share Posted June 2, 2016 I only use sport if I really want to accelerate hard. Otherwise ECO. It's just a fabulous car and ultra-stable in my opinion. Quote Link to comment Share on other sites More sharing options...

Gearoidmuar Posted June 3, 2016 Share Posted June 3, 2016 I don't have a sunroof in mine, but did in my previous car, a Honda Accord diesel. It is the most useless accessory you can have in a car! I used it maybe 5 times in ten years. Quote Link to comment Share on other sites More sharing options...
Dixgas Posted June 3, 2016 Share Posted June 3, 2016 Did a run to Nottingham from Westcumbria last weekend in my Mk 3 250 ( A66/A1M/M18/M1 ) set off with bags of time to spare so controlled the urge to use it 206 horses and kept under the limit, the computer gave a reading of 43mpg going and after a more urgent return, 38mpg. Pretty impressive for a 2.5 V6 don't you think. I brimmed it before the start and knowing the miles covered will fill up on Monday and see what reading I get from that.

L3xu5gt Posted June 3, 2016 Share Posted June 3, 2016 Impressive, it's how u drive it. Next time I'm on a long run I'm gone try it it in sport mode and see if it's the same. Quote Link to comment Share on other sites More sharing options...
