hugh64 Posted January 28, 2008 Report Posted January 28, 2008 why am i only getting 420 mls to a tank in my 2000 19tdi galaxy you must get better mpg than that ???????? Quote
gregers Posted January 28, 2008 Report Posted January 28, 2008 dunno with the cost of fuel i cant afford to fill mine up,but im getting about 60 miles out of a tenner.but it is mostly short journeys our car does. Quote
stevie m Posted January 28, 2008 Report Posted January 28, 2008 (edited) If i drive at 70mph on a good run i get about 70-75 miles to a tenner. I do a lot of motorway miles tho. It would drop quite a bit to about 60-65 miles to the tenner Edited January 28, 2008 by stevie m Quote
DaveJH Posted January 28, 2008 Report Posted January 28, 2008 Yes, 550 or better to the tank full seems right : equivalent to 75 for Quote
MadBaz Posted January 28, 2008 Report Posted January 28, 2008 Yippe someone in an oilburner getting same mpg as me :lol: Quote
mumof4 Posted January 29, 2008 Report Posted January 29, 2008 A few things affect MPG as we all know..: Is your right foot made of lead?Are your tyres at the correct Psi? ( always check when tyres are cold )Is the car serviced regualy?Do you brake sharply? Accelerate hard?Are your journeys stop and go?Do you make a lot of short journeys like school runs where the car is switched on and off after a short space of time? All these and propbably more contribute to lower MPG. :lol: Quote
naim32 Posted January 31, 2008 Report Posted January 31, 2008 (edited) When I fixed the Aux heater I noticed a drop in mpg so it could be down to the cold.Most of my journeys are to work and back at 15 mins each. The heater is still running at the end and so for most of my miles the heater is always on and at full power for most of the journey. The fuel consumption of the heater is approx 0.6 liter / hour so for me estimate 0.3 liter per day. I'm in Austria at the moment so the outside temp is around -3 deg C.I drive 15 miles a day (60 mph autobahn) at around 36 mpg (from display) giving a fuel consumption of 1.875 liters. So for me the heater is taking approx 14% of fuel. If I work this back to a full tank of 70 liters this gives 480 miles per tank. On long journeys across Europe at 70-75mph I can get around 600. Also I think winter diesel has something added to stop it freezing during the winter. I have heard that this additive can reduce mpg by about 5 mpg. Edited January 31, 2008 by naim32 Quote
Gwaredd Posted January 31, 2008 Report Posted January 31, 2008 My wife found that our Alhambra (115 PD) was terrible on fuel when the Aux heater broke. We struggled to get 400 miles on a tank, but as soon as we fixed it, it jumped back up to 550+. The Aux heater is there for a reason, so check it's working. Quote
stevie m Posted January 31, 2008 Report Posted January 31, 2008 (edited) When mine broke i never lost much i pulled the fuse to stop it and it was fine. :lol: Edited January 31, 2008 by stevie m Quote
gregers Posted January 31, 2008 Report Posted January 31, 2008 an ex bmw technician told me that the booster heaters are fitted not just to get the cabin warmer but also to make the engine run more efficiently and to help in lowering the emissions. Quote
naim32 Posted January 31, 2008 Report Posted January 31, 2008 Mine failed due to the usual --- the glow plug died. I thought that if the glow plug is dead then the control module doesn't even attempt to start the heater and therefore no fuel should be injected.My mpg seems to have fallen once it was repaired which makes sense. The mpg reading on the dash may not take into account the heater since the fuel line it has an independent fuel line. So, if your seeing an improvement on the dash display then this may only be due to the engine warming up faster. On the subject of the heater heating the engine as well, I assume this is correct. I have been trying to find some info on how the heater is plumbed in there are several configs on pg 10 of the DW5S technical description http://www.eberspacher.com/files/pdfs/wate...s_technical.pdf Does any know which one we have ? (on a mk2). Quote
zeplin43 Posted January 31, 2008 Report Posted January 31, 2008 Another fuel economy reminder i get a 0.7 liters economy if i run the climate control on ECON instead of Auto. Climate control gives you the chosen temp.I think that this economy is due to the ac compressor is switched off when we press the econ button.Well this is 70 liters fuel economy every 10000 klms.Are there any other fuel econ tips that you guys can remind us of.
