unleaded with a cat?
I´ve got an F650 GS with catalytic converter. I´m headed for Brazil where I hear unleaded fuel is non-existant. I have heard different views on what will happen if I put leaded in the tank. I thought it broke the cat, and becuase of the sensor feeding info back to the electronic brain, the fuel consumption rises dramatically. I have also heard that people have had no serious problems except for slightly lower fuel efficiency caused by low octane levels.
Should I go to the effort of trying to get a new exhaust without CAT in Argentina, which I will have to dump again back in the UK, or just wing it and see what happens.
