Right you are Kranzy...
and habib There are only a few main reasons why most people wont convert...
1. Upfront cost of the conversion
2. Loss of power
3. Being a 4 cyl, they arent TOO expensive to run on petrol anyway.
My counter statements are that the rebate basically covers MOST of the conversion cost, so it doesnt matter if you have to pay it, you get it back. The loss of power, yeah it bothers you a little bit, the most noticeable lost on a converted car wtih no tuning is the acceleration. Its not as punchy as when on petrol, but as noss said, take your punt and raise the compression and you can make some good figures. And finally, yeh it isnt too costly to run on petrol, but i fill up once a week, $30 normally, $35 if i run it bone dry, and it will last at least 400km, which sadly is only what my car could do on petrol, so it ends up being over 50% cheaper for me.
It depends how you like your car, if i ever want to give it some decent stick, i just switch it over to petrol and it still has some get up and go, just the added weight of the LPG gear would affect performance when running on petrol.
Another pro, if you may call it, it lowers the back about an inch LOL.
If you do end up converting, pay attention to the warning sticker they put on your car window. Never press the accelerator on startup, it causes the biggest fucking backfire you will ever hear. And if you feel necessary, start the car on petrol every morning, because if you dont your injectors will clog up, as mine did. After 2-3 minutes switch it over to gas.
But all in all, im still ever so glad i converted.
