not good

Its Naptha, or "white gas" like coleman cooking stove gas. Check the label. I believe it has a major percentage of this. Go to Walmart and park in the farthest, most vacant spot you can find in the back. You buy a jug of clean oil and a filter, and 2 cans of Seafoam. Take the power brake hose off and stick it in one can, start the car for about 5 seconds until it all gets sucked into your intake. Shut car down and hit up the McDonalds in the store and have yourself a nice long lunch. Go back out and pour 1/2 of the other can in your oil filler, and the other half into your gas tank. Put your power brake hose back on and make sure no car parked behind you. Roll your windows up and start the car. Get it to a fast idle and watch as billows of white smoke start pouring out your exhaust. Rev the motor a few time and itll eventually start to burn off and the smoke will die down. Now get the hell out of there before the fire trucks start showing up. Drive it home and you'll probably want to change your oil. Its comical how much smoke this produces...
