As a Sharetank owner, your card will automatically be charged if the fuel price is cheaper at the pump on the day you filled up than your weighted average Sharetank balance. Read more about savings here.

If you would like to change this setting to use Sharetank regardless if you get a savings, you can change this under the Fastlane menu.

  1. Open Z App
  2. Tap 'More' on the bottom right and tap on 'Fastlane' in the menu
  3. Tap on the three dots (…) in the top-right corner 
  4. Tap on 'Sharetank presets' in the Fastlane menu
  5. Turn off the toggle: "Enable paying the lowest price".

Please note: right now you need at least 15L in your Sharetank to use it at Fastlane. If you have less than 15L, Fastlane will always use your backup payment method.
