Can I use TetraBOOST in a car fitted with catalytic converter?
No. All cars fitted with catalytic converters are designed to run on lead free fuel only. A number of enthusiasts with highly-tuned or re-chipped cars, such as Nissan Skyline GTRs, Subaru Impreza P1s and Mitsubishi Evo Series, are removing the catalytic converters and using TetraBOOST as an octane booster and anti-knock agent.
