Adz Posted February 21, 2008 Share Posted February 21, 2008 Bummin 'eck! 230 miles to a tankful! Have you been driving it with the handbrake on or are you doing 'warp factor ridiculous with yer hair on fire' down the motorway? Best I've managed with my '93 was 36mpg (Somerset to Cumbria), steady 55mph pretty much all the way... topped it off with 43ish litres when I got there 324 miles on the trip (approx 5% speedo/odo error thanks to big tyres - TomTom "can'treadamapnav" corrected to 340 plus change). With the roof bars and ladders on top (read as buddy gert parachute effect that makes the aerodynamics of two mating housebricks look quite good) I get closer to 30mpg at around the same cruising speed and easily 300 miles to a tank. Most I've ever managed to fit in the tank was 50 litres... didn't realise I was down to the last 4 and a bit, mind you it seems I might be the owner of the only accurate Land Rover fuel gauge in existence as it was still just a little bit above the empty mark.

Cheers, Mine does 27mpg mostly round town so its all stop start - more than a dozen sets of traffic lights in 8 miles on the way to work.... Its about 220 miles to the tank before I fill up - usually just above the red. At 70mph its a few mpg less which is close enough to the official land rover figure in the handbook for a 300tdi - IIRC they quote a figure of around 20 mpg at 75mph. Yes you can get more mpg with a very light foot but its not usually possible in todays traffic conditions ( stuck behind lorries) or causing traffic queues and getting flashed by irrate and inconsiderate drivers, and for some of us, time is sometimes more of the essence. There are numerous threads on here about mpg, but for a tdi 90 those figures are common... Quote Link to comment Share on other sites More sharing options...
storm99 Posted February 21, 2008 Share Posted February 21, 2008 i bought a 1987 2.5 disel 90 recently and was warned about a dodgy fuel tank sender unit, however i decided to completely ignore this advice and when it fell to just under half on the guage i ran out of diesel...totally astonished i was. Now i threw in 5 litres from a jerrycan and drove 1, i repeat, 1 mile to a fuel station....i then filled up the grand total of 38 litres. And before you ask yes it was pouring out of the overflow as i didnt expect to stop so suddenly! I have since this never driven more than 180 miles without filling up (300km over here) and its usually 30 litres to fill her up, so 10km/litre which aint bad ( i think thats about 28-30 mpg). I could either run her dry again on purpose after filling up to check the capacity but i cant be arsed honestly. As far as im aware its a standard tank, so thats about 45 litres, 10 gallons. Hope this helps the original question, but never trust it anyway....i'm going to get a sender unit one day, after the ex-wife, the kids, food, blah, blah blah......

JST Posted February 22, 2008 Share Posted February 22, 2008 Storm - it sounds to me like your fuel pickup isint in the correct place - try lifting the seat and taking the top cover off and having a look to see how far down into the tank it goes.

Farmerfred Posted March 29, 2016 Share Posted March 29, 2016 What the tank will hold and what the book says are usually 2 different figures, the book says 'useable capacity', In my previous 1994 300TDi Disco the book said '60 litres useable capacity' but in actual capacity it held more like 80.

miketomcat Posted March 29, 2016 Share Posted March 29, 2016 Well I can safely say you can get 53.25lt use out of a 89 ninety tank though I thinks I was cutting it a little fine oops. Mike Quote Link to comment Share on other sites More sharing options...
Farmerfred Posted March 30, 2016 Share Posted March 30, 2016 Book tank capacities are as follows. Rear, 110 & 130 models, 79.50 litres. 17.50 gal. Side, except 110 SW, 68.20 litres, 15.00 gal. Side, 110 SW only, 45.50 litres, 10 gal. Side, 90 models, 54.58 litres, 12 gal. Quote Link to comment Share on other sites More sharing options...
pat_pending Posted March 30, 2016 Share Posted March 30, 2016 Does anyone believe anything a Land Rover fuel gauge tells them? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 30, 2016 Share Posted March 30, 2016 Sure. Gauges always work perfectly for me. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted March 30, 2016 Share Posted March 30, 2016 My gauge is good enough that I can generally predict the fuel economy to within an mpg or two based on it's position and the trip mileage. For example if the trip mileage is 180 at an indicated 1/2 tank then that will equate to something around 30-31 mpg. Okay it's not 'accurate' in that 3/4, 1/2 and 1/4 don't necessarily correlate exactly with those measurements due to its non-linear nature however it's reliable and repeatable which is arguably more important once you have got to know the vehicle and how the gauge behaves.

pat_pending Posted March 30, 2016 Share Posted March 30, 2016 I find the gauge in mine gives a "rough estimate" and the lower the tank level the more inaccurate it is. It's one of those endearing quirks that make ownership a joy. Besides, once it's dark you can barely see the gauge anyway. Quote Link to comment Share on other sites More sharing options...

Cheers, 36mpg from a Defender. Think I'd have to see that to believe it. Quote Link to comment Share on other sites More sharing options...
Farmerfred Posted March 30, 2016 Share Posted March 30, 2016 I think when calculating your fuel consumption in MPG for a Defender you have to remember that your speedometer is calibrated for the vehicle fitted with 7.50x16 standard wheels/tyres as most if not all Defenders I know of on 205R16 the speedo reads 4 mph more than you are actually travelling.

Retroanaconda Posted March 30, 2016 Share Posted March 30, 2016 36mpg from a Defender. Think I'd have to see that to believe it. Best I've had was a verified 35mpg, so 36 is probably achievable if you drive like miss daisy in good conditions. Not difficult to correct for speedo error with the use of a GPS.
