Expensive Petroleum is when you are low on petrol and you go to an expensive gas station and ask if you can pay for the petrol and they say €300+ . You watch so much Harry Potter you say EXPENSIVE PETROLEUM (expecto patronum is in Harry Potter)
You: How much for the petrol?

Shopkeeper: €500

You: (watches to much Harry Potter) EXPENSIVE PETROLEUM!!
