Nissan Patrol 2009: 4.8-litre liquid-injection gas conversion?

Asked by Jarrod Hunt

I'm looking at buying a 2009 Nissan Patrol 4.8-litre and converting to gas using a new liquid-injection system. Have you heard of any problems associated with this set-up?

We haven’t heard of any problems with the new liquid-injection technology, but it is relatively new and yet to be fully proven like the alternative vapour-injection system. There is plenty of debate over the benefits of liquid-injection, the proponents of the technology claim substantial increases in power and economy, while opponents, those who favour the well-proven vapour-injection technology say the benefits are minimal and not worth the risk that comes with being a pioneer and adopting the new technology. As an aside we have heard that Ford has delayed introduction of its Euro 4 E-gas engine, which was to use liquid-injection, for at least six months. While the reasons for the delay are not clear, it has been suggested it could be because of refueling problems at high ambient temperatures. That’s speculation at this stage, but whatever the problem it’s serious enough to have Ford going ahead without an E-gas option for the next few months.
