Using Rewards Points
However, there is a downside to the 20 gallon threshold. Many of the vehicles on the road today will not hold 20 gallons if nearly dry. Further, fuel pumps are commonly located in the fuel tank. Fuel surrounding the pump keeps it cool and should be refilled when the level reaches 1/4 of tank capacity to prevent premature failure and expensive repairs. Rewards are available for discounts for a maximum of 20 gallons of fuel. If the vehicle holds less than 20 gallons the balance of points is lost, denying the customer of the full earned benefit of the program. One option would be to allow the use of points for smaller quantities of fuel. Another option would be to allow unused points to carry over toward future purchases. Other options may be useful as well. Some modifications to the system would be more fair to consumers who earn the rewards.
The views expressed here are my opinion and worth what you paid. Personally, I try to fill my vehicle and my wife’s vehicle at the same time so that I am able to get full benefit of my points and neither one falls below the 1/4 tank refill point.
