Summer grade diesel contains more wax and energy than winter diesel. However, when used at low temperatures, summer grade diesel may gel and cause engine problems. Therefore, it is important to buy a grade of diesel to match the temperatures you will be operating in. In the event of a price war there is always the temptation to purchase as much fuel as possible. Those with underground storage tanks are in the best position to take advantage of low prices.
Underground tanks provide the best long-term storage capabilities.
However, before purchasing fuel for long-term storage, carefully consider the interest costs, tax implications and your ability to maintain the fuel in good condition. Make sure the tank is securely fastened to the truck. The potential liability in losing a tank containing fuel on a highway is horrendous. Gasoline is code number 1203 and diesel fuel is code number 1202. If you are transporting over 2,000 litres, all required placards and a short form manifest should be used.
