AWD Fuel Consumption

[macropod]

I've recently returned from a 1K round trip to Canberra and averaged 14L/100km on LPG running a mixer system on my TJII AWD. That was with 2 adults and 2 kids and more than a bootfull of gear. Tyres are Dunlop SP300E 215/60/R16 on standard rims and running 34PSI. I believe it's the original oxygen sensor and the car has clocked 199K. It can use up to 20L/100k on short trips and I've seen it drop to as low as 12.8L/100km at a steady 100km/h.

I think you need your O2 sensor checked/replaced. I've managed better than 14l/100km on regular unleaded petrol towing a caravan with my 2005 TW VRX AWD ...

I'm going to get the O2 sensor replaced at the next service. Today I drove from Geelong to Melbourne and back and the LPG consumption was 11.7l/100km. I do this trip regularly and this is the best fuel consumption I've achieved to date. I'll be thrilled if it improves after the O2 sensor is replaced. At 51c pl it's cheap motoring for this type of car.

Hmm... I got a new radiator, condensor and transmission cooler and battery was disconnected for some time. Now the transmission shifts much smoother (almost not noticeable). I shift manually all the time. The consumption is also coming down (13.9). Is this due to a new radiator? I doubt the thermostat was replaced.

No. I had it done a while back and it got replaced due to a small incident. Someone's towbar poke through grill and into the radiator etc.

That does seem somewhat high. I'd suggest getting your O2 sensor checked/replaced. A faulty sensor can cause the car to run an overly-rich fuel mix.

If you are spending your time in Sydney or heavy urban traffic that isnt too bad, you dont have to drive hard in those conditions for the fuel to dissapear. I drive my AWD TJ here in Canberra to and from work in light traffic with 80 and 100kmh freeways with a few traffic lights and tend to flog it from the lights to redline once or twice using the manual shifter and get 14.5. You only have to accelerate faster than the surrounding traffic a few times to keep your consumption up.

When I drive long distance I get a 9.4-10.0

Been averaging high 13s to low 14s per 100km when driven spiritedly on my daily drive. Have for two weeks driven it moderately sedately and it has dropped to high 11s to low 12s per 100km on the same route.
