Improving economy?

[DaveM]

My Safari (RD28T) has never got better than 16L/100km, anyone know what I can do to improve this? Filters etc are new, injectors reconned, but still crap economy.
Mates are getting 12L/100km, but all are manual, surely an auto wouldnt bump it up that much?


Cheers,
Dave

Ive gone from a 2.7 TD Mistral auto back to a 2.7TD Terrano 5 speed and the differance between them is fairly big in the drinking of diesel between Inglewood and Te kuiti the terrano uses 11 liters less than the Mistral and has way more grunt than the Mistral.
The only time i realy have to change down is on the hill at mohanui but most diesels would most like have to change down there.
My next change will be bigger tires to drop the RPM and save fuel that way.

Woohoo! My 3.5 V6 Paj gets better than that!

How do you drive? What tyres are on it? What rpm does it turn at 100km/h?
Manual/auto?

The best I'd expect from that combo (indirect injection diesel pushing a barn) would be about 12-13 litres per 100km. Bigger tyres, softer tyre pressure and an automatic gearbox and it'd be about right.

I get 10km/l from my rangie. But it's high geared (2000rpm at 100km/h), more aerodynamic than a safari, has skinnier tyres and direct injection.

This is the SWB GU shape one correct?

Elmo has a GQ 2.8 should see what he gets out of his.
I get 12.5-13.5L/100km with mine on 35's,5inch lift,auto with a lock up switch which is on 90% of the time when on a trip(when on tarseal)gearing on the auto's(GQ) is very tall and made worse with big tyres,if I fitted 4.6 gears in diffs I might be able to get under 12L/100km.

What size tyres you running?
How much boost?have you changed it?
Has it got std exhast system?

[DaveM]

Mine the GU shape, running 33's, but no engine mods. Only get 500km max from an 80L odd tank.
Don't thrash it, and mates in oz can get 6-700km/tank with 35's

Definately something not right there Dave. I'm getting 12L/100kms or better from mine and its no slug.

Might be worth asking on Outerlimits if you haven't done already?

Have you checked the filter inside the fuel pump i found my mistrels one was blocked up and once cleaned things improved big time?

[DaveM]

Didn't really think of the banjo filter, I know it was a problem on the TD42, so will look if there is one on this too, and will post on outer.

Cheers for the advice guys
