With a normal car it may be instant to not turn over to bend a valve if that is what in fact it did .
But Honda has a little thing called v tec so while the car is idled or not reved high the timing is not advanced enough to cause any piston valve slapping. As soon as the rpms raise and its is activated the valves start to bend. If the gas is old it may continue to run but not when cold as the compression is low from the valve being bent so it cannot fire.
Hope this makes sense. Either way the mechanic is a crook and should not be trusted with a donkey cart never mind a civic.

I'll be doing this. I tried to siphon the gas out but the hose only goes halfway down the filler neck before it stops. There is an obstruction of some type, perhaps a fuel stealing guard, perhaps not. At any rate, the gas shall not be siphoned via hose and pump.
It's at a little under 1/2 tank of the old gas. I'm going to fill the rest with new and go burn through the tank.
Thanks again for the advice.
