I honestly dont think a cup of it is going to harm it at all, if anything run it for about 1 k miles and let it clean your engine up then go get a oil change.
I also use it to de-carbon a engine by slowly pouring it down the intake of a car. Makes one hell of a smoke screen, but afterwards it will knock the carbon build up off the valves and pistons making the car run a lot better if it used to be owned by old farts, or to the store and back.
it kinda chokes and sputters at times since it is about 20 years old now, it's a 1987 lebaron -
I wonder if that would help it?
I would start with the obvious first, tune up.
When you pull your plugs out look at them and if you can look into the spark plug hole do that as well. If the plug is cover in black soot or just very back in general thats carbon build up. It gets on the pistons and stays hot causing desiling (engine run on), spark knock when you accl or going up hill giving gas, or can build up on the valves not allowing the to close properly making the car run bad.
If you decide to do it you must pour it slowly down the throttle body while it is running and you will have to give it quite a bit of gas. Try to make sure the exhaust is point down wind and away from public places because it will smoke like a mother fvcking bitch, people will undoubtedly think you car is on fire and call the fire department, yes it will smoke that much. When you first pour it in you should see a blackish white cloud of smoke pouring out the tail pipe, the black is the carbon. After about half the bottle stop pouring and continue to rev a little bit till the engine clears up, then proceed with half a can of carb cleaner. This stuff will smell bad, burn your eyes, and will burn the inside of your throat if you inhale while spraying, so take a deep breath, give the car some gas, and spray down the throttle body cleaning any left over tranny fluid. Use about half a can. Your done. Rev a few times to clear out engine, walk away and breath, and if carbon build up was your problem should run like a new car.
Only do this again if your car is old, high miles, and shows signs of carbon fouling. If not wasting your time.
