Double Cabs......

Do any Double Cabs return more than 30mpg driven on long motorway runs or are they all in the twenties?

TIA

Orve.

I get about 29 mpg on country roads on my Navara. Manage about 34 on dual carrageways (no motorways this far north). Running on BFG A/Ts but well pumped up. Cruise control helps. Playing around with a spider tuning box at the moment. Might be getting 36 in between tripping the engine management into safe mode.

Black though.

Towing an empty Erde biscuit tin perhaps.

Do you have a computer in the LR? Those are impressive figures you're getting. Our TDV6 Disco wont do that well.

No Computer, the 6 speed box is just great.

Is the Disco Auto?

Why, should I have? Saw enough posts about the spider and was bored so I thought I would give it a try. Seems better but without a test facility I wonder whether its just the mind telling me that it must be better after shelling out 400 quid+.

About 1 week after I started playing with it the oil warning light started to come on intermittently. Thought I had screwed the engine and quickly took it out. Turned out it was just a dicky pressure sensor.

P.S. The figures I quoted are pretty exact since the BFGs are about 7% larger in circumference and now my speedo is bang on against the GPS. First thing I noticed on putting on the BFGs was a drop in mpg. Thought it was down to the rougher tread but then realised with the standard tires the computer must be overestimating mpg since it is overreading speed/distance.

That's cos the D3 weighs as much as the Moon and TDV6 engines are normally broken

My mate has a L200, he uses the throttle as a switch, we both did a tow to Swanage my LR V8 @ 15mpg beat him, his only returned 17mpg, factoring the higher cost diesel (quite at time) mine was the cheaper. My poor mate was in denial till I showed him the fuel reciepts and the tomtom calculated milage of his route.

Cant wait to repeat experiment when new Isuzu 2.8 is in the LR.

I can confirm Jono Garton's figures from my TDi300 LWB, similar load, possibly a tad better on towing. Less overtaking and general zipping about does it I reckon

Sorry CP, that's what I meant. Better than Jono's 25 mpg on tow...
