We appreciate that it is difficult sometimes to tell exactly how much oil you need. However, because oil prices decrease the more you order, the Supplier does reserve the right to increase the price per litre if the amount you order is substantially more than your tank will take.
Effective route planning is a critical factor and Suppliers load their tankers and schedule a delivery run of orders so as to return back to the depot with as little fuel as possible. Carrying fuel back is not cost effective for the Supplier and ultimately impacts on prices. So getting our order volumes reasonably accurate will help oil users in the long run.
