Discovery TD5 fuel consumption

[QUOTE=discorevy;2761139]Add 10% to your odo reading when working out your fuel consumption ( bigger tyres ) , mud tyres will also use more fuel , 130 kph will use a heap more than 110, especially on a lifted 4x4 with roof rack etc , has the new motor been swapped like for like ? , eg 10p for 10 p or 16p for same ? ( lots of hardware and software differences) I'd suggest selling your dp chip and getting a proper remap as well as a decent intercooler, cheap snorkelsalso don't help fuel consumption. Do you have an egt gauge?[/QUOTE


I believe it was, would have to dig up my old invoice.

thats the plan, already have a nnn ECU to install, just néed to save for a intercooler.

i wouldn't call a safari snorkel cheap

running a madman.

EGTS at 125-130ish average around 570 give or take a few and pending on the gradient of the road.
Coolant sits between 91-95 ( pending abient temp outside)
gearbox temp sits between 92-105 pending ambient at that speed

obviusly as as soon as I back off EGTS drop. At 110 they are in the 400's

cheers Chris

no , safari is fine , I was making more of a generic statement about the cheaper brands . If you deduct 10% for tyre size your around the 15.5 l/p hundred , with the lift / mud tyres , rack , dp chip, standard intercooler, ambient temp up there at this time of year etc at 130 sounds about ballpark, I reckon your IAT would be up there at 130 , what year is the D2 ?. Ask your mates with lifted, racked muddy shod toyonissa****i what their honest consumption figures are at 130 kph[bigwhistle]

Absolutely box stock D2/TD5, stock 235/70-16 tyres with just a TJM bullbar on the front and a parachu..., err, a rooftop tent on top [biggrin]

Last two tanks, loaded right up as I'm moving house, the first I didn't exceed 110 on the Federal, Hume and Pacific Highways and averaged 11.7l/100km, the next tank I was sitting on 120km/h in the 110km/h zones between Coffs and Alstonville (trying to make an appointment) and I've been running around Lismore, Alstonville and Ballina the last few days and got right on 12l/100km.

Not too shabby.

I think I averaged around 12.5l/100km on the trip back from Alice Springs in April/May.

Yeah! .. what size were the all terrains .. compared to the MT's?

Across the Nullarbor with roof tent aerodynamics I got a personal worst of 14.8 L/100 when cruise controlling at 110 (~2400 rpm in 4th locked up) with a decent cross wind the whole day. Best so far is 11.7 when cruising at 90 (~1950 rpm, TC locked). Running 265/70 R16 with speed ratio correction unit (true speedometer and odometer, thanks hunter di spares :)). It’s all about the optimum ratio of rpm, turbo boost, velocity and wind resistance. Also throttle technique on the hills to avoid rev spikes. If I drove at 130 all day I would expect 16-17 L/100.

Same 265/75/r16's

I've averaged 12.29L/100Km over the last 40,000Km.

Been running 245/75R16 Cooper STMaxx tyres for the last 5-10,000Km prior to that it was 245/75R16 Bridgestone D674 MT. ARB Front bar, winch, Rhino Rack Pioneer platform, Mantec RAI, Td5inside remap, Allisport intercooler, steel rear bumper.

Normal non-towing use sees 10-11L/100Km, towing a 1500Kg camper trailer at the legal speed limit sees 14-16L/100Km.

My speedo & odo read the same as my GPS as I have a speedo corrector fitted.
