LPG conversion for Landcruiser 100 series

Submitted: Wednesday, Sep 04, 2002 at 00:00

JOHN

I have a 2001 100 series Landcruiser petrol auto which has a great thirst, especially when towing a caravan.
I am considering having an LPG conversion installed which uses the space adjacent to the side steps for two additional tanks, giving a total capacity of approximately 200 litres.
The cost quoted is about $2600 and I estimate that it will take me about 3 years to recoup that before I am saving $.
I am looking for reasons why I should not go ahead.

John, The only reasons why I can think of are the space that the LPG tank takes up and the fact that you will find, if you read your warranty carefully, that an LPG conversion will void the warranty. At least it does for mine.

Thanks, the installer tells me that the conversion supplier will provide an engine warranty for a modest amount, but I have yet to investigate this in detail

John, I asume your 100 series has the 4.5lt 1FZ-FE? What is your fuel consumption?

I have a 75 series with this engine, manual transmission. On petrol 5.6ks per litre, on Gas 4.5ks per litre. So you won't reduce the thirst it'll increase, but the cost is cheaper (so far).

I've done 100,000ks on gas and its still going strong. A mate with an 80 series and same donk on gas has clocked up over 200,000 without any problems.

I bought the vehicle with gas already installed. There was backfiring problems on decelaration or going down hills. I shopped around, and it took a few, until I found a Mechanic who new what he was doing - problem solved.

Thank you Rod, I currently get about 4.5kpl when towing my van (approx 2.5 tonnes). Your figures confirm my estimates.

My wife, who normally drives the vehicle, would not entertain the idea of a diesel, plus the cost differential was approximately $15000

John, a couple of things to consider. Firstly, a colleague has a 100 series similar to mine on gas. He is contemplating taking it off (and it maybe for sale) because in the Apple Isle gas is nearly 60 cents per litre and he claims it is cheaper to run on straight petrol. Secondly, if you are going to carry 200 litres of gas you had better factor in a suspension upgrade on top of your installation costs. I speak from experience that the standard suspension will deterierate quickly after a few accessories are added and your first trip into the boondocks is completed. One final point, if you plan to venture into the interior the availibility of gas declines and prices rise. It is available in most major tourist towns, but not all though. I have discounted the conversion on mine and have decided to replace the sub-tank with a aftermarket 170 litre tank and definately make the most of cheap petrol when I find it. Hope this helps. Cheers
