I made the mistake of adding oil without a funnel and it spilled all over the engine. The cleaning took forever and even after that there was still some residue on the engine which caused it to smoke when the car was first started. It was a stupid lesson and I bought these funnels immediately. They work great, keep things clean and don't smoke!
