Just bought a car and got it home and went to change the oil.
Done a routine change, started it up, quickly went into the kitchen to let my wife know I was nearly done and within that 20 second window, oil had burst out of the bottom of the engine and the oil light was on.
I had only had the car for 3 hours.
So tell me, what’s your biggest f*ck up?
I drained the transmission fluid instead of engine oil. When the liquid came out neon green my heart dropped.
