Free Fillin’® Rewards Program

Free Fillin’ Program – Join Now! 

In 2010, Tesoro introduced the Web-based Free Fillin’ Loyalty Program. To join, simply visit the new Free Fillin’ Website at www.TesoroFreeFillin.com!

Here’s how the program works:

As a Tesoro customer, you will be awarded with one (1) Free Fillin’ Voucher for each ten (10) gallons of qualifying Tesoro motor fuel purchased during a single visit to a participating Tesoro location. Qualifying motor fuel purchases include the following products only:
(a) Tesoro branded gasoline marketed using Tesoro trademarks
(b) Tesoro branded diesel fuel
 
Example:
• Less than 10 gallons = No Vouchers
• At least 10 gallons and less than 20 gallons = 1 Voucher
• At least 20 gallons and less than 30 gallons = 2 Vouchers
• At least 30 gallons and less than 40 gallons = 3 Vouchers
• etc…
 
Once you have a voucher, visit the Free Fillin’ Website to register and start entering codes. Registration is quick, easy and FREE. After 25 vouchers are entered, Tesoro will reward you with a $5 Tesoro reward card, which can be used for motor fuel or merchandise at participating Tesoro locations.*
