Ok, I'm going to do my best (as a mechanic) to give you a straight answer...despite the obvious humor in what you did.

Consistency has nothing to do with how an internal combustion engine works....the fuel has to be flammable to start with. Gas is shot into a cylinder and then ignited to create the energy that moves your vehicle, dish soap is funfortunately not flammable.

In short you've ruined and/or caused thousands of dollars in damage to your vehicle. The tank is trash unless it can be dropped and then dipped in some abrasive chemicals to remove ALL residue of the dish soap. It would most likely be less expensive to buy a new tank.

The fuel lines are trash, the filter is trash, the fuel pump is trash, the injectors (carb if it's an older car) is ruined, the plugs are trash, the cylinders may or may not be damaged...the list goes on. Expect to pay 3-4k to repair the vehicle...even then it will probably never be right.

This was a hard way to learn a pretty simple lesson. Good luck to you and remember...don't ever put anything that isn't gasoline in the tank of your car.
