Anything other than the required fluids needed to run an engine (gas, oil, coolant) can seriously damage any engine.
Anything other than gasoline
yes it does damage your car and your car wont run ; ]
Depends on how long it was run on regular gas and how much damage occured to the engine when it was run, empty the tank and put the proper pre-mix gas in it and find out.
It will shut off, run like it's running out of gas, will damage fuel injector, fuel finter, coil packs, exc.
If you managed to find any leaded gas then No, it will not hurt anything.
Yes, it is possible to use regular gas in a 2001 BMW X5. However, the engine will not be able to run as well, and could damage the car in the long run.
Not really. Fill up with the "correct" octane when you run some fuel out of your ride.
This is BAD. You must not try to run the car, if the bleach gets into the engine then it will cause serious damage. Yo will have to have the gas tank replaced.
Please take it to a licensed facility for evacuation and recharging. You could do damage to your system if run that way and damage to the atmosphere if you release the gas manually.
