Lava and oil don't mix, any more than lava and seawater mix.
While the lava surface will be cooled slightly by the oil, there is a lot of heat in lava and the oil surface will be heated rapidly, leading to vapourisation and probably burning, as most types of oil are flammable.
The outcome will depend on the volumes of the oil and lava, but as there's likely to be a lot more lava than oil, the oil will vapourise and probably burn.
Water is much more effective at stopping lava. Water is available in large quantities, it cools lava down and makes it set, while vapourising as steam without pollution.
Because of the amount of heat in a lava flow, it would take vast quantities of water sprayed across the face of the lava to stop it, and the resulting wall would be increasingly fragile as it grew higher, as only the surface of the lava would be cooled, not the pool of molten lava behind it.

What happens if you mix lava and water together in Minecraft?
When water meets a lava 'block', the lava is converted into an obsidian block. If water meets 'flowing' lava then the lava is turned into cobblestone.
What happens when you mix water with oil and salt?
When you mix water with oil and salt, the salt will dissolve in the water but not in the oil. Oil and water will not mix as they are immiscible, forming separate layers due to their different polarities. The salt will stay dissolved in the water layer.
What happenens if I mix regular oil with synthetic oil?
Nothing happens, they just mix. You can buy "blended" motor oil.
When you make a homemade lava lamp what happens when you add water to the plastic bottle?
When you add water to a homemade lava lamp, it will sink to the bottom of the bottle since water is denser than oil. The oil, being less dense than water, will float on top of the water, creating the visually appealing "lava lamp" effect when you add an Alka-Seltzer tablet and food coloring.

The mix won't set properly, and the lifespan of your cement form will be shortened considerably.
