Will I pay more per gallon if the tank will not take the full order?

We appreciate that it is difficult sometimes to estimate exactly how much oil you need. However, because oil prices decrease the more you order, the dealer does reserve the right to increase the price per gallon if the amount you order is substantially more than your tank will take. 

Effective route planning is important and dealers load their trucks and schedule a delivery run of orders so as to return back to the depot with as little fuel as possible. Getting a closer amount to what you need is more cost effective for you and the dealer!
