All goods and services fluctuate in price. Fuel fluctuates more quickly, because the end product is closer to the raw resource.
If you look at things like oranges, they will fluctuate quickly if there is a sudden drop in supply. However, they'll normally change in price more steadily as their price is usually controlled by bigger factors like input and fuel prices, labour, etc...
Other goods that fluctuate like fuel would be things like gold, silver, etc..
In other words, when the supply is determined by the availability of the good itself, you see sharper ups and downs. When the supply is determined by larger factors in the economy, you tend to see a steady move that is dependent on the economy.
