Thread: D3 Quick rundown for the uneducated?

By the sounds of it I should take comfort in owning the 4.0L petrol D3, especially when looking down at the average fuel useage even if it isn’t 100% accurate. Countless posts of diesel d3 owners saying the petrol 4.0L are a slow gutless engine that drinks the fuel no matter the situation.
10 km/L shown in pic which then went to 10.5km/L
If the petrol 4.0L Engine in the D3 is so **** where are all the reported failures?

The Petrol 4.0 like all the other engines are very reliable. The 4.0 petrol will often return better fuel consumption around town.

My mates d3 4.0 petrol would get half a litre to a litre per 100k better than my 4.6 V8 D2 on the highway and about 4 litres per 100k worse than mine around town. We had many runs together under different conditions and would compare at the bowsers. Imcluding up to Cape York and the OTT. His had done under 100,000 and ran like a gem too. He didn't have bar work etc unlike mine that had plenty of added weight and big Duratracs. His was auto and mine manual - the manuals in the D2 V8's do a fair bit better economy wise than the autos. The 4.0 is a sweet reliable engine and I would own it any day over the 2.7 in a D3. The economy gauge on the D3 in his was optimistic too compared to actual mileage from the odometer and fuel used.

I am of the opinion that for general use, light towing and touring the V8 D3 or D4 is the best pick. I say light towing ONLY for those requiring decent fuel range , as in all other respects they are a better pick than the diesel. Far less maintenance costs and almost unheard of failures.
I seriously considered a 5.0V8 L322 and even a 4.2 Supercharged , however the fuel consumption while towing our block of flats would be prohibitive for extended travel.
Thankfully, the 4.4TDV8 has so far proven to be a reliable and economical engine.
I would be happy to consider other makes of vehicle to achieve a reliable tow vehicle, if oneday there were no LR products to fit the bill..😲

Justin the V8's in the D3 are so nice but rare in the second hand market unfortunately. Not many sold and many that had them hung into them.

That was our issue trying to find an 8cyl D3 in qld. Across all of Aus there seems to be less then 10 for sale atm. A shame as it would have been a great engine.

D4 SC s are even more rare...I'm guessing less than 20 in Aus maybe?. Shame given they are such a sweet reliable powerfull engine and quite good on fuel too. Yes the diesel is better for economy and range but I'd trade a few bucks per 100 clicks to avoid major service and repair costs.

Over the last month with some heavy towing and occasionally heaps of right boot 😎 I'm averaging 14.2 l/100ks. We live in a hilly area so we're never going to get 12s.

My d2 new engine averaged @12s for the same monthly use.

But there's no comparison re comfort, safety features and sheer urge.....

Curious if anyone knows.
The 2.7 was also used in Jag and Peugeot but in twin turbo form.
Do they also suffer the same crank issues?
