1993 Cougar Specs
I made an electrolizer my Corolla and a smaller unit for my 150cc scooter. I got tons of bubbles so I expected stunning fuel consumption. In the end I chucked them out because they made no difference either to the power or the consumption. Remember, your alternator will be working flat out all the time to keep up with the energy needs and this alone will affect your consumption. Secondly, your engine management system will notice that your car is running leaner and will richen the mixture to compensate. More fuel consumption. You might find that you will put a lot of effort in for little or no return. The only solution for high fuel consumption, apart from a properly tuned car, is a lighter foot.
