Actually, trace amounts of fuel get into the oil under normal circumstances. The reason is that, even though the piston rings seal against the cylinder walls nearly completely, the seal is not perfect, and trace amounts of fuel will escape past the pistons and get into the oil that is below the piston, thus mixing with the oil. Under normal circumstances, this is a minute amount that, if you change your oil regularly, will never cause a problem. There can also be extreme situations where large amounts of fuel can get into the oil. This is caused when there is a problem, such as a stuck fuel injector, an inoperative ignition system, or a fuel flooded engine, where the cylinders are overwhelmed by fuel, and the piston rings become unseated from the cylinder walls, and there is a breech that allows larger amounts of fuel past, into the oil below. If this happens, once the problem is repaired, the oil needs to be changed.
