Perform Oil Smell Test

What happens here

After the flammability test, the presenter performs a smell test on the engine oil. First, he pulls out the engine's dipstick and smells the oil directly from it. Then, for a more direct assessment, he removes the dipstick and smells directly from the dipstick tube on the engine. The goal is to detect any distinct odor of gasoline mixed with the oil, which would indicate fuel dilution. The presenter concludes that he can't definitively smell gasoline, stating, "I can't tell whether I smell gas or not."

Goal: Detect gasoline contamination in engine oil by smell.
