Why does this matter to you? The price of diesel fuel has a direct impact on the cost of transporting a vehicle. And the further you are shipping your car, the more price increases are going to impact the total price of shipping.
According to the US Energy Information Administration there has been a steady increase in prices since September throughout most of the US, and prices are at their highest levels since May 2010. So, you can expect to see the price of shipping your vehicle increase this month and beyond.
