Should a TD5 be driven at low revs?

I'll probably get howled down for this,,
but across the desert BUB91 was quite happy to be loaded right up at 1000 revs, even lower when you had to,,
I think the 8 cylinders make a big difference down low.

Inevitable :cool:

Arrrooooooooooooooooo.....

:wasntme:

Ive been driving many different turbo diesels for over 20 years. The FM12 Volvo I drive at work now, uses a rev range between 1200rpm to 1800rpm :eek:
Ive found driving my D2 td5 to a max rev's of 2500rpm (instead of 3000rpm) I can easily get 10.5-11 litres/100ks. Even on a resent trip from ACT to Thredbo and back. This was driving at and just above the speed limit, passing when I could and using cruise control.
The Volvo gets 48l/100ks pulling 32 tonne-ish.

just my 2 cents worth,,,
:tease:

Is that the D12D? I thought 1100-1800rpm. Not that 100 rpm makes a big difference.

The world's biggest diesels have a redline of around 125 rpm :eek:

I'll have to search for that pic of the ship engine I posted ----:eek2::eek2::eek2:

found it----

That's the great thing about petrol, and all that capacity and cylinders. :)

OK. Mine revs up to 3000 on take off. If take of up a steep hill from near slow then up to 4000. Normal cruising once it's moving comes down to between 2-2500rpm. Mine is not standard though.

I try not to let my TD5 get down to 500rpm - its starts to complain if I open the throttle. 900 is much better!

On a recent trip my 3.5 Rangie was happy to pull 3rd gear from revs so low as to let the tacho needle virtually sit at zero rpm...
