Hybrids are even more expensive than diesels!
Another interesting point in these tables - the two most expensive cars to run in the small car sector are the two hybrid cars - the Honda Civic hybrid affording a direct comparison, being about 12.5% more expensive to run than its conventional counterpart.
By contrast, the only LPG one I noticed was the Falcon, and here the lower fuel cost translates almost straight into lower running costs - since it is only about $1500 dearer.

My diesel is heaps cheaper to run then a petrol...
Good thing about diesels is that I can go to my local fish and chip shop, pick up their old oil an run it on that. I still add some diesel to it as I'm running a single tank but it's only costing me the equivalent of about 50c a litre. Sure I have to put a little of my time and effort in but I think it's definetly worth it (plus I'm helping the environment - win / win :) ). Sure, you can run a petrol car on LPG but a) you loose quite a bit of power, b) the LPG consumption (l/km) is usually much higher than with petrol and c) very few cars come from the factory with that option.
I think I'll be sticking with my diesel for a while yet...
