Thread: Defender Fuel Economy

Hi Jim
No doubt there is but anyway my 02 Defender has a factory 75 (usable) litre tank and I am currently getting 9.0 l/100kms.
Running 235 85 R 16 General Grabbers and have the following fitted;
Bar and winch , drawer set and 2 long range tanks just to give an ide of extra weight on board.
Snorkel fitted and no roof racks fitted.
The daily drive is a mix of stop/start and Freeway , about 50/50.
Range is therefore 700 kms safe

10K/l is reasonably achievable, 75l tank work on 600K between refuels.

Thanks for the info fellas,

I had the one owner of a 110 i'm interested in buying tell me he only gets 12-13l per hundred and only 350km from a tank.

The wagon is basically stock standard (no extra accessories on it) could there be some engine issues going on there?

Thanks again,

Jimmy.

Maybe the roof rack on mine ............ but I've never managed to get 10.
Usually around 11+

I get about 650Km per tank combined driving in a 300Tdi.

I can't seem to get much better than that.

On daily use unloaded (50%freeway ~90km/hr:50% stopstart) I consistently get 10.2 - 10.6 L/100km.

Driver only, rhino roof bars, steel rims, Maxis 753 tyres (~56psi) 235/85/16, egr removed, ~21psi boost.

I found that when filling up the fuel tank can still take another 3 - 7 litres after it has clicked off. So if I am calculating efficiency I will trickle fuel in until I can see the fuel and top up until level stays the same (patience is needed here). Sometimes there can be an airpocket which can throw out efficiency calcs.

I have never achieved 9 L/100km. Best was 10.0 L/100km

That only works out to 45 l per tank. He might be very heavy footed but even this sounds excessive.

My 98 TDi wagon gets around 800 km from an 80 l tank, or down to 500 if I'm towing my big trailer (approx 1200kg). I once got better than 10 towing a box trailer with a suspect wheel bearing so had to keep speed below 90.

Coincidentally, my TD5 Disco goes the same distances from 95 litres, but it is auto and I go a little bit quicker.

Hi, I have a 02 defender td5 and around town with a lot of short runs so the engine doesnt get warmed (till the weekend) I get about 11.5-12/100k's but I also have 255/85 r16's maxi bighorns and the front suspension is a bit saggy(bullbar + orig suspension) so both will make more drag/ drain on fuel efficiency for my car.
