A per-mile tax on Oregon miles, usually reported monthly. Oregon takes no diesel tax at the pump, so cheap-looking fuel there is not a saving.
Who needs it
Vehicles at 26,001 lbs gross or more on Oregon roads.
How you get it
Set up an account with Oregon's Motor Carrier Transportation Division and report miles, usually monthly. Temporary passes cover one-off trips.
The part that catches people
Oregon charges no diesel tax at the pump, so cheap-looking fuel is not actually cheaper — you pay on the mile instead. Budget for it rather than treating Oregon fuel as a saving.
