HOLDEN uses a dual-fuel gas-injection system developed by Impco. I am a fan of gas-injection systems because they are less prone to the driving problems that can plague the older venturi-mixer systems and make them a nightmare to drive. The dual-fuel Holden hasn't been a big seller mainly because fleets prefer the dedicated LPG Falcon. The dedicated LPG system means drivers can't switch over to petrol to get better performance and driving capability. But if you are a private owner, I would choose Holden's gas-injection system.
YOU'RE probably right and it is a faulty fuel sender, but Holden has told you they will consider your claim once it's found that yours is a problem, so they have in fact come to your aid. Do what they have requested you do and you should be taken care of, if, as you believe, your fuel sender is faulty.
DRIVING around Australia today is a very different proposition to what it was in the 1970s. The roads are much better, communication has improved out of sight, and there are more dealers and service agents on the route you're likely to take. Back in the 1970s you went in a big Aussie six because they were tough and unlikely to break down. They were also easy to fix on the side of the road, and parts were relatively easy to get in the middle of nowhere. Today, if you're sticking to the blacktop, I would take a Commodore or Falcon and there are plenty available within your budget. But if I were going off the beaten track I would think about a four-wheel drive with its higher ride height for ground clearance, its ruggedness, and its drive system. Early Nissan Patrols, like an MQ, or early LandCruisers would be good, reliable and tough transport.
THE VYII had the old Buick-derived 3.8-litre ECOTEC overhead-valve V6, which dated back to the VN Commodore. It was a pretty tough old nail, with good torque characteristics and good fuel economy. The VZ has the new 3.6-litre quad-cam Alloytec V6, which has more power and torque than the ECOTEC engine, but I don't think its torque characteristics are as good. It's also a little thirstier than the older engine. I don't see a lot between the resale values of the two, but being newer the VZ will command a higher used price for the foreseeable future.
FUEL consumption is mainly determined by how you drive and 17.5 litres for 100km out of your 5.7-litre LS1 V8 ute suggests you have a heavy right foot. The 14.0 litres per 100km you quote sounds like the official ADR fuel consumption figure and not real life, so it's not comparable with your own experience. I reckon you would get slightly higher fuel consumption out of the 6.0-litre LS2 V8. Higher torque can help fuel consumption by making it easier to drive the ute with less throttle opening. The 6.0-litre LS2 went into the ute in February 2006.
HOLDEN by Design was a range of accessories and options developed for Holden by HSV and fitted at the Woodville factory. They ranged from dual-fuel systems to body kits, wings, wheels and other things that set them apart from the regular run of Commodores. I don't believe they make a car any more valuable.
YOU really should decide if you want performance or economy. If you want economy, go for a Corolla, Civic, 323 or Pulsar. You will find they have pretty good performance anyway.
REAR-AXLE noise is a problem in both the Commodore and the Falcon, so I wouldn't rush to fit a Falcon diff to your car. Rather I would consult a diff gear specialist who would be able to diagnose the noise and advise you on fixing it.
I'M AFRAID it's dead. It was dropped from the range almost two years ago when Holden was gearing up for the VE. The company is only producing models on the VE architecture, and the one-tonner really can't be done on that platform.
