Which would flow faster down a 10cm ramp inclined at 30 degrees, apple juice or motor oil?

I would think apple juice cause it runs faster than motor oil which is thicker.Which would flow faster down a 10cm ramp inclined at 30 degrees, apple juice or motor oil?
apple juice...always, doesn't matter the degree of incline. Juice is thinner and will flow faster.Which would flow faster down a 10cm ramp inclined at 30 degrees, apple juice or motor oil?
