so i just got the car a few days ago, it rained today at work and i noticed a rainbow effect on the pavement, this happens when i stop driving and park. i wasnt able to get a jack and lift it up but before i do that any input on what it could be? maybe oil, gas, radiator fluid. whats the scoop???


heres the general area of where it came from
not my car but used it for reference, the fluid was diluted from the rain and was about 2 feet in circumference i dont think it was oil but i could be wrong, it was very rainbowy

 

it can be either your distrubutor o-ring is bad and it leaks oil
or it can be that one of your anti-freeze hoses has a hole
