_Matt_ 42 Report post Posted July 17, 2010 ok after refining my figures i have a correct kpl Around town spirited driving: 15.9L/100km Around town economic driving: 12.6L/100km Yet to take it on the open road. Quote Share this post Link to post Share on other sites
str8_6 275 Report post Posted July 18, 2010 Since purchase, I reset the M5 OBC consumption 1 and it's average is 15.1 L/100km however that will be mainly due to city driving which I do much more of now. Open road driving I've seen as low as 9.6 L/100km on average from consumption 2 which I think is pretty reasonable considering. I know I need a fuel filter change, I wonder if that will make any difference? Quote Share this post Link to post Share on other sites
1rotty 40 Report post Posted July 18, 2010 (edited) What is involved with a professional 'tune'? How much does it usually cost? My OBC is reading 8.9L/100km, but I don't believe it. How accurate are these? I'm too poor to fill the 75L tank to test properly . When I first got the car on the road it got up to about 16L/100km. E30 325i Manual In my case it was a remap but have it done by someone with the right diagnostic gear.And that was what mine was using Edited July 18, 2010 by 1rotty Quote Share this post Link to post Share on other sites
Greg111 13 Report post Posted July 18, 2010 Round 350k to a tank in the M3, yes it is running very very rich, always has. Remap should fix that right up Quote Share this post Link to post Share on other sites

R90S 2 Report post Posted July 18, 2010 I get about 11litres/100km or 9km/litre out of both the M3 and the Legacy GT in a mix of open road and suburban driving. I don't get caught in traffic jams or peak-hour bumper-to-bumper due to our rural location, and typically get about a 450km range in the Legacy before needing a refill. I always reset the tripmeter when I fill the tank and monitor the distance, partly out of interest and partly to cross-check the fuel gauge. I also reset the tripmeter on my bike and use that as a fuel gauge, because (like most bikes of the '70s) it was never fitted with a gauge when new. Happily though, it gets about 18km/litre or 5.6litres/100km which, because of it's 24 litre tank gives it a range of almost 400km. Quote Share this post Link to post Share on other sites

ler4_war 1 Report post Posted August 8, 2010 how much does it use? how do you drive it? is it auto? is it hilly where you live? i only drive it around the city (wanganui) and my location is not that hilly, more of a flat. i had mine filled up for 50$, its 25.8Liters. Now the current mileage is at 144Km, and its a bit close to the mark where i had it filled up. so my prediction my 3.16i is around 6-7km/L. what can u recommend? cleaning MAF,throttle body, injectors??

A good tune helps economy...HEAPS, getting in there, cleaning throttle body may help and unless you run your petrol very low often i would not think injector cleaner would help much. 25.8 litre tank? seems very small! My 318 is 55-60ish litres and normally costs around $90-100 to fill and ranges from 500km-750km per tank depending on hills and open road running. 6-7km per litre sounds very low, is that cruising and stoping at light a lot, are you heavy on the accelerator, i have noticed particularly in my little 1.8 that when i'm heavy footed the economy goes down the drain.

So when I get to a mechanic what service will I tell him? yeah i know 6-7km/L is very low. my 3.16 is automatic.. any help on this guys? thanks..

nickbawt 0 Report post Posted August 11, 2010 The E34 normally does about 13L/100Km around town with a lot of stopping and going. Open road the missus can get it down to about 9.5, whereas my best is only 10.5! Different driving styles huh . It was running quite badly a wee while ago, getting about 18L/100k.. rough idle, lack of power etc turned out to be the pipe from the airflow meter to the engine inlet had worked itself loose, bloody hard to see! had me a bit worried though! Also, what do you guys reckon about running wider tyres.. you reckon it affects fuel economy much? Quote Share this post Link to post Share on other sites
