100 series petrol cruiser fuel consumption on tour

I think when he said "which is around the same economy as a diesel." he was talking in dollar terms not litres.

Nav...80L for 330 km is 24.2 L/100km..that is high even for a petrol 100 series cruiser...I think you should be looking at around 16- 18 L/100k...now what sort of LPG set up is it? Sequential Injection system or the older system?, if the first you can expect about 12 - 20% penalty in consumption, if the later, maybe 30%.
My suggestion would be to take the vehicle to a reputable mechanic/LPG installer..get them to go over it.

LPG is now available at 3500 servos all over Australia, go to teh oli company websites and down load a trip planner, you will be surprised just where teh stuff can be brought nowadays.

Good luck.

Yeah I was talking in dollar terms peter.
I worked out with the assistance of a web site the following formula:

Diesel - distance - 120lt of diesel - $180.
Gas - distance 330km - 80lt of gas - $60

Based on these approximate figures, the gas returned 0.18 cents per km and the diesel returned 0.18.8 cents per km. The gas was 24lt/100 and the diesel was 12lt/100.

Now, I have yet to tow anything over 1.5 tonnes behind the cruiser yet, so I have no idea of what the figures will be then for the gas. I assume there will be little change as surely the cruiser fuel consumption can't be much worse under tow.

Now based on the above figures, and I have been kind to the diesel at 12lt/100, I have heard the diesels under tow use around 15 - 16lt/100. If that is true and the I am about right for the gas figures, I am better off staying with the gas for reasons like less service intervals.

Thanks Rodeo - jayco for your reply, you are right there are more gas servo's than people realise. I heard there is even gas in the centre. I have still yet to look further into ways to extract some more economy from the petrol like exhaust and a foam filter.
The injectors have been cleaned and the motor is serviced every 10 thousand.
I probably will not part with the petrol as I am a sucker for power and the 4.5 has plenty of that on tap, especially helpful when towing Nissan's out of the glue.

Thanks again gentlemen.

Whoops, forgot to put in the distance for the disel, 1000km.

oldbaz, the figures are crap.
I cant remember what the figures before the gas were, bugger.
I believe 23-24 is the norm, unless someone else can correct me.

The motor has 204 thousand on the clock, so she has plenty of life left, I heard these motors are bullet proof if well looked after.

Yeah a compression test is next on the list and some further investigation.

I have woken up to the engine swap idea, too costly.

Thanks Alan, I have heard on numerous occassions that towing at 90-100 saves fuel, but in reality its obvious.

Everything you have said makes sense, thankyou.
