Orgasmic Farmer Posted February 20, 2009 Share Posted February 20, 2009 devide litres by 4.54 for gallons and devide that to your milage.. gives 29.11 mpg Quote Link to comment Share on other sites More sharing options...
maxtherotti Posted February 20, 2009 Author Share Posted February 20, 2009 cool thats not bad as 85 of those miles were towing a 26 foot caravan and the rest a mix of round town and a road bombing about with a heavy right foot rob Quote Link to comment Share on other sites More sharing options...
landrover598 Posted February 20, 2009 Share Posted February 20, 2009 The clue is in the title, miles per gallon, miles divided into gallons. 29 sounds good, as i can't can't figure out why mine is only doing 20 Quote Link to comment Share on other sites More sharing options...
maxtherotti Posted February 20, 2009 Author Share Posted February 20, 2009 car is a 98 300 tdi manual disco has been de catted,de egr,d tweaked fuel pump,itg foam panel air filter and brunell uprated intercooler like i said 85 of those miles were pulling my 26 foot 1800 kg caravan too so im well chuffed with that rob Quote Link to comment Share on other sites More sharing options...
Anderzander Posted February 20, 2009 Share Posted February 20, 2009 I get 29 to 35 from my td5. Mostly around 31/32. Quote Link to comment Share on other sites More sharing options...
Rich_P Posted February 20, 2009 Share Posted February 20, 2009 Those figures look so pleasant. On my Land Rover's last 120 miles or so, 80 of which were to and from Liverpool at 60, it averaged 19.4mpg. One of the joys of a 2.25 litre Petrol.

maxtherotti Posted February 20, 2009 Author Share Posted February 20, 2009 29.11 looks very nice to me after the range rover just a shame it dont sound like the rangie did but then filling that back up with gas after every 150 ish miles (approx 65 litres of gas so 10.4 mpg) used to get boring rob Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 20, 2009 Share Posted February 20, 2009 its litres divided by distiance, or other way round not exactly sure but i have a feeling its the first mikey Quote Link to comment Share on other sites More sharing options...

lrfarmer Posted February 20, 2009 Share Posted February 20, 2009 well your doing better than my rrc 22.9mpg on the first check. but i'm still learning to drive it an auto ecanomicly used to get 30 out of the disco Quote Link to comment Share on other sites More sharing options...
ChrisV8 Posted February 20, 2009 Share Posted February 20, 2009 To be really accurate you need to check it over several tank fulls, I keep total anorak mpg records for my road cars so the (dare I say it) JEEP Patriot has averaged 42.69 mpg from day 1, it's got the VW 2 litre diesel which is renowned for good economy. My Rangie with a 200 tdi is now giving a smidge over 30mpg, but it doesn't do too many miles also spends a lot of time in low range greenlaning, so I am well pleased with that as well.

maxtherotti Posted February 20, 2009 Author Share Posted February 20, 2009 i would have pref to have had a rrc tdi over a disco if im 100% honest but this disco seemed a good buy (before the clutch went lol) and the lack of very good 300 tdi rrc under 3k left me little option but im starting to like the disco more now i have started to get the little bits sorted rob Quote Link to comment Share on other sites More sharing options...
Night Train Posted February 20, 2009 Share Posted February 20, 2009 I used to have a spreadsheet in Excel where I would enter the date, the mileage, the litres of fuel and the cost. The spreadsheet then gave me a running average for each fill up and for the month and year along with the costs. I could plot a graph of mileage and fuel consumption over the year to see when I was more efficient and when I was doing more mileage. In my car it has a trip computer that tells me for each trip, much easier but no long term record. Quote Link to comment Share on other sites More sharing options...

maxtherotti Posted February 20, 2009 Author Share Posted February 20, 2009 i didn't pay 3k for mine but it is a convertion not factory fitted i looked at 1 very late m reg soft dash factory 300tdi that was top money for me (£2800) and was super shiney and mint inside then i crawled underneath and spotted the distinct lack of sills/x member and boot floor said ill pass and it was sold the next day!!! the disco by comparison is very solid underneath bit has a few scabby bits on the outside rob Quote Link to comment Share on other sites More sharing options...

maxtherotti Posted February 22, 2009 Author Share Posted February 22, 2009 im my numbers above are lots of town runs of under 3 miles there and back o and work is exactly 1 mile door to door too so that prob dont help either rob Quote Link to comment Share on other sites More sharing options...
West4x4 Posted February 22, 2009 Share Posted February 22, 2009 im my numbers above are lots of town runs of under 3 miles there and backo and work is exactly 1 mile door to door too so that prob dont help either rob Then why drive? i rarely use mine the short runs around town i've been doing lately were only because of moving heavy stuff couldnt make the gf walk home the half mile from work with the 2 batteries she got me! simerly helping a mate move a mile ocross town would be tricky on foot. Usualally only use it for long runs out of town Quote Link to comment Share on other sites More sharing options...

nicks90 Posted February 23, 2009 Share Posted February 23, 2009 i used to work out my mileage quite accurately - and then i realised when i was using my gps one day that the speedo was out by about 10%. So that meant all my fuel economy figures were out by the same. Absolutely no point doing it unless you are completely sure your speedo is accurate. I used to be well pleased to be getting an average of 32mpg out of my tdi 90 until i realised the above, so therefore my real mpg was 29... Mud tyres, snorkel and fuelling tweaks put paid to that figure! Down to about 25-26mpg now. I dont bother checking accurately anymore, all i do is an approximation of how much i get to a full tank of diesel. If i see the overall range dropping by a good margin, I know somethings wrong or it needs a service. With a new air and fuel filter, I get about 50-80 miles more per tank.

jules Posted February 23, 2009 Share Posted February 23, 2009 My wife's 4.6 hse I just don't want to know what it dose to the gallon on her weekly trip to London or Wales. The Disco is the same although its a TD5 I just don't want to know as it only depresses me. The funny thing is I borrowed my mums Laguna to drive the three hours to Donnington for fear of the cost of fuel but all the wife could say after the first 45 mins was I'd rather we paid the extra £40 in fuel and went in the rangy then on the way home just before we got home in the winchester traffic after induering six ours of complants about how littls she could see and how uncomftable the car was she stated "You can forget getting a estate car you just drive too fast we'll just have to stick with the Disco and RR" I was gutted Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted February 23, 2009 Share Posted February 23, 2009 my 300tdi 90 saw around 30mpg whilst travelling back down the M1 between Huddersfield and Watford last night. I was very impressed, it had been down on the rest of the trip due to strong head winds and some off roading at Tong, with figures ranging between 18 and 25 between fuel stops.
