Why buy a Diesel?

[BigJon]

Did a 400 k trip on the weekend. Mixed bitumen, dirt touring, dirt tracks and low range work. One of the other vehicles on the trip was a TD5 Discovery auto. He used 60 litres of fuel for the 400 km. My 88 Range Rover 3.5 V8 manual (never rebuilt, about 250 000km on the clock) used....


















60 litres for the 400 km!!

Ive just gone half a tank in my V8 Disco and 306km on the trip meter thats Damn good in my opinion should get 600 out of this tank

I have found that the V8 can be fine on trips as when you get it to a steady speed then they are fine on Fuel. But when you go past the 140kph then they start to sup it hard. I used to drive to work in my old V8 rangie. was fine at 130kph but go over that, which i used to do home useally 155 Kph then it would use alot more fuel than 130 kph. But still did not stop me doing 155 almost everywhere apart from at the end of month (just before pay day )

Don't think my rangie would ever do 155kph

[BigJon]

Mine neither. 140 kph on a good day . I was driving gently for economy, but we were all traveling at the same speeds, at the same time over the same terrain. I was expecting him to get much better economy than me.

There's only 3 probs with ripping around at 150 km/h+ on public roads.

1). It's illegal.
2). The donk sucks like there's no tomorrow.
3). If plod reads this thread, you could be in some deep doggie doo........

But a long time ago, I saw big numbers on the speedo at a driver day at Oran Park, in the then new 95 Rossignol V8, went like a rocket! I was amazed!

what was he doing towing two v8's?

what was he doing towing two v8's?

He was towing bigjohn, and his figures were just the engine idling !

Good point but this was in the Uk. Police sort of turn a blind eye up to 145kph
145- 160kph 3 points on your licnces and 30 pound fine(if you get caught)
160 Kph and above lose you lincense and win a bike

So most people drive on the motorway at 150kph

My old rangie will do this quite happy and that was a 3.5 carb . My 90 used to drive around at 90 mph (145 kph)

In my experience in owning diesels they do about 25% better fuel economy than a petrol motor in similar vehicle driven in similar fashion.

I am surprised a new diesel did the same as your v8, something must be wrong with it.

After owning 2 Turbo Diesels 4wd's and 2 petrol 4wds, my experience was whilst Diesels got better fuel economy, it was somewhat negated by the pricing variation between Diesel and Petrol at the pump and the higher maintenance schedule on the Diesel motors.
