Thread: for those thinking about LPG here is my feedback

The next statement that will arrive is: That will all change when they lift the excise on LPG.

My answer is the excise will never get as high as the excise on petrol, if only that they don't want the taxis to switch back to petrol for the pollution issues and that's exactly what will happen if LPG and petrol are taxed at the same rate.

Its a well publicised rate that tops out at a quite reasonable 12.5% in 2015 .
I'll look it up - by the time it kicks in we will be paying $1.40 a litre for petrol anyway.

You should have mentioned how much kinder your Disco is to the environment on LPG...

Thank you Blitz!
Please note this was achieved with the latest Gastec FP-50DS LPG processor and oxy sensor, so its as good as you can get without modding the petrol for oxy sensors too.
You have one more year (1 July 2011) before the first 2.5cpl of excise hits LPG.

LPG is indeed more cost effective and if you are doing the K's to warrant it go for it. However LPG burns at a higher temperature than petrol and so damage can be caused to the valves if they are not made of hardened metal as in the case of Ford six cylinder motors. Check to see if your motor is able to handle the higher temperatures before converting!!!

We pay that sort of price for petrol now anyway!
The price varies from $1.30-$1.47

I believe the issue is that LPG is a slow burning fuel so that the peak temperature is lower but heat load overall is slightly higher. It is mainly the lack of lubrication in LPG that causes wear with soft valves and seats.
Traditional Rover V8's all seem to be able to handle the extra heat loading due to the alloy heads being a good heat conductor and are with hardened seats. Some at-risk engines benefit from upper cylinder lube such as Flashlube. Modern engines with gas injection can be set up with petrol addition under load or electronic metering of lube with the newest Flashlube computerised kits.

Yes agreed!!

We're already in the high $1.30's for petrol last week and the price of crude continues to rise as the GFC eases.
