Well, I'm in Europe and I earn my living working on mainly European cars and American motorcycles and have done for 35 years....While you "may" be right, many European car manufacturers warn strenuously against running the vehicle dry and the reason given is catalyst damage.
Can you tell me how you can run any European vehicle or from any other place on the planet for that matter when it has no fuel?......If you can we can make millions here
You have fuel, you have combustion, you have no fuel you have no combustion, no combustion you are not running the engine and by default you are not using the cat.......simple really.
Every time you switch off your vehicle you have in essence run out of fuel, as the ignition system is cut and the fuel system is cut, just like it is when you run out of fuel...You cannot damage a catalytic converter by not running your engine..
The only way fuel, can damage the cat is if it is unburned fuel as I said in my previous post....
Running out of fuel CANNOT harm your catalytic converter!
Dude, think about what you're saying here....:smile2:
