Oregon Biofuel Blending Requirements for Gasoline and Diesel.

Oregon law has a 5% Biodiesel and 10% Ethanol fuel blend mandate.

In Oregon, you can expect to buy a biofuel with every gallon of gas or diesel, whether you are buying at a retail pump or commercially delivered bulk fuel. Unless you are expressly seeking out a ethanol-free premium unleaded or off road heating oil expressly free of biodiesel, you can expect the fuel will have a low carbon blend of biofuel in it.

Why does Oregon have biofuel blended in every gallon of fuel?

There are several layers of rules, requirements, and incentives placing a minimum of 5% biodiesel blend in diesel and a 10% ethanol blend in gasoline. The City of Portland’s Bureau of Development Services provides information and resources on the background of both Portland and Oregon’s requirements.

Oregon state has a 5% blend mandate for all diesel fuels sold statewide. Portland has its own standard of for 5% biofule in diesel, which is slightly different but functionally the same as the states. Oregon’s standard requires B5/R5 if it’s sold into  machinery (dyed off road or clear on road diesel), which requires a 5% biofuel component. In the  formation of this Oregon statewide mandate, renewable diesel was considered acceptable.

Oregon also has a 10% ethanol blend mandate for all gasoline fuels with a few exceptions. Portland has this same rule as it mandated ethanol blends prior to Oregon state. Oregon has exceptions for ethanol-free premium unleaded.  (Warning: the City of Portland has no exemption for non-oxygenated premium fuels) though there are some sellers of it. Oregon state’s exceptions being premium gasoline for aviation and non-ethanol premium gasoline sold at retail gas stations. This was adopted later after the initial Renewable Fuel Standard mandates. Portland did not follow Oregon with this flexibility for small engine or classic car enthusiasts seeking non-ethanol fuel.

The rules that drive biofuel use in Oregon’s fuel:

The City of Portland has its own Renewable Fuel Standard (RFS) which is seen in Portland City Code Chapter 16.60 Motor Vehicle Fuels. This RFS requires all diesel sold (either commercial or retail fuel) to contain a minimum 5% biodiesel (specifically methyl-ester molecule). The RFS also requires all gasoline sold (either commercial or retail gas stations) to contain a 10% blend of ethanol. In addition to this fuel blend requirement, Portland also has requirements for the original feedstock biodiesel is made from. Portland requires that 50% of the biodiesel feedstock be sourced from recycled vegetable oil, canola oil, and a few other types available in the Pacific NW.

The State of Oregon has its own Renewable Fuel Standard. It is less restrictive than Portland’s, allowing renewable diesel or biodiesel to meet its 5% blend requirement. You can find the law in Oregon Revised Statute 646.922. The Oregon RFS also requires a 10% ethanol to be blended with gasoline. There is an exception for premium gasoline to be ethanol-free.  This fuel is commonly called “Non-Oxy Premium” or “Clear Premium” by those seeking to order it.
