mixture of this in a 92 supra

what would happen if i put a mixture of sand, salt, and sugar in a gas tank of a supra? just curious:smokin:

That just might be the replacement for 116 octane, lemme know how it works out for you.

seriously, would it mess up the engine or what?

Hypathetically, if your fuel system is still good the only thing it should do is sit in the tank. Your fuel filters should block anything foreign going into the motor. The only thing you would want to do if it's already in there would be to drain and drop the fuel tank and clean it out. I would do that before trying to see if the car would still run but it's your call.
