i dont understand you guys over there, we have been paying up to $1.50 a litre for crap unleaded fuel over here for ages, but the best way around the problem is lpg or propane , i do lpg/propane conversions its safe , powerful, better octane than petrol(gasoline) better for the environment (almost zero emissions), quality is more reliable its a better fuel all around , every servo has it in oz, great for the daily driver , we are now fitting it to diesel trucks , 25% power increase less carbon emissions ,cheap at 40cents per litre , i had a friend over from atlanta last week hes trying to get it pushed over there , apparently its noy at servos there?the technology is booming in lpg/propane equipment and our major supplier is impco ( california)i wouldnt fit it on my challengers but great on your normal runaround car/truck/etc ... the std impco 425 mixer/gas carb will flow 300hp or more then theres the new technocarb lpg carb from the usa apparently thats flows up to 800hp, i havent had one in the shop yet but cant wait , whats wrong with 2X 4 bbl gas carbs(425 impcos) on a dual quad big block ( thats my next daily driver project ) as petrol gets too bloody dear over here gas conversions are a huge business , the federal govt are doing a $2000.00 rebate for every car converted, the average cost is around $2800.00 , savings in running costs are around 50/60% on average , very little /no difference in power, lpg is the future fuel as it can be retro fitted to any internal combustion engine , the hot rodders are into it now as emission laws kill the early cars so lpg is 99% no emissions! and the benefit to the environment is a bonus!
