My Feb 00 Forte Wagon has Tickford gas, I dont really notice any difference in power when running on gas. What does happen though is that when you start the car on gas it has a moment when it seems to be lacking fuel. According to the mechanic this happens because the car starts on ULP then switches to gas a couple of seconds after starting. I'm not sure if this is normal. I have found that turning the ignition on, doing up the seat belts etc before starting the car usually reduces the rough idle a fair bit. As far as ULP is concerned I run the car on gas till its nearly empty then switch to ULP for 50ks or so before I fill up with gas. I wouldn't have car like this without gas thats for sure. 47.9 as compared to 112.9 cant beat it.
Yeah AU98C-Wagon, I know how it is. In Melbourne it's roughly 34 compared with 98!
