There seems to be no direct evidence that any planet was thought to be covered in oil.
Some sources seem to point to Venus but there is no reason that Venus would have oil apart from the early belief that because Venus was covered with clouds, clouds meant rain. Which meant that the surface of Venus had water. because of it's proximity to the Sun, it must be warm. So what has a lot of water and is warm. Swamps. What did swamps have, a lot of trees. Aka the carboniferous period when vast quantities of carbon was laid down which would have produced quantities of oil, gas and coal - as on Earth.
However, this did not happen.

How far is planet x from the sun?
Planet X is a hypothetical planet once thought to exist out beyond Neptune. Astronomers discovered a discrepancy in Uranus' orbit that they thought indicated another planet beyond Neptune whose mass was affecting it. When Neptune's mass was determined using data gathered by Voyager 2, Astronomers discovered that the discrepancy was entirely due to Neptune's orbit. Since then, other trans-Neptunian objects have been discovered, but none large enough to be considered a planet.
