In this tutorial, we learn how to find an oil leak using florescent dye. First, you want to pour the dye into the oil canister and let the car run for about 10 minutes. After this, turn the lights off in the garage and grab a florescent light, and bring it into your engine. You should now be able to see where the oil is leaking from inside the engine, so you can fix the problem quickly. The accuracy of this method is 100%, and you won't have to second guess yourself that you have the wrong source of the oil leak in your car.
