Has anyone else heard anything about the fuelcat, it is placed in either your fuel line or fuel tank and allows you to run leaded fuel cars on unleaded with great results. They are also very cheap, around $65-$80 for a motorbike and about $200 for a car. Apparently the idea has been around since world war 2 when the russians invented them to run there planes on higher octane fuel. You can buy them at Union Jack in Melbourne. I know people who use them currently and they give them a great wrap,(say it works better than when it ran on leaded), just wondering if anyone had used them.
