Thread: Simpson in a D1 V8?

Bloody heck! 40L/100!!!!!!!

A D1 V8 driven sensibly in winter on the sand with correct tyre pressures WILL NOT USE as much as a V8 or 4.5 petrol 6 landcruiser. These things see some serious fuel consumption as they weigh in at 2.5 to 3 tons at least when loaded.

Keep the weight down, service and tune the vehicle properly prior to departure and pay attention to the tyre pressures and gear selections.

Does that sound about right???

Sorry couldn't help myself!

I know 40l/100km is crazy, but thats what it used on lpg towing recently, so i thought it would be a safe figure (not happy with economy after recent "tune" by mechanic).

True JC, if i had a match that would solve all the problems as its insured for heaps more than its worth and then i could get a diesel

Forget GAS, it is very uneconomical on low compression engines with worn camshafts.....Prior to the trip you should be concerned with max economy on fuel only. The low comp 3.9V8 can happily take lots of spark advance, and ensure your vac advance unit and distributor are working correctly.

If you are getting worse than 30l/100km driven sensibly then I would be surprised, most of all however keep the weight down..... Every Kg has to be stopped by the brakes, accelerated by the engine, turned by the steering and supported by the suspension. All this in a soft and friable substance (Sand). Think about how much effort it takes for a person to push a wheel barrow along bitumen and then suddenly onto soft sand....Now THERE'S a comparison for you

Weight down, throttle pedal up. I normally get around just above idle where possible. Oh and keep the speed down on the dune faces unless you like the axle housings hitting the bumpstops.
I did it in 85 litres in a Tdi, unrelated of course but surely you won't use twice as much?

I have read this also, but why in a diesel would you need 180l for 500-600km unless there route is much longer?
Thats why im worried if i can carry enough in the V8.
