Where does the oil pattern on a bowling lane start and end?

Answer 1

It starts right near the foul line and usually extends 38 to 42 feet from the foul line. That leaves about 20 feet of lane surface that is without oil, including the pin deck. These measurements are for when the oil is first applied. As bowlers bowl on the pattern, some of the oil migrates further down the lane, as the balls thrown pick up oil and then deposit it on the way to the pins. This is referred to by bowlers as carrydown oil.

Answer 2

A traditional oil pattern that tends to be in the middle of the lane leaving the edges dry for more friction/hook. This is used in most Bowling lanes
