Types of Motor Fuel Consumed in California:


The state's air quality standards limit the types of motor fuels sold for vehicles to:

EPA Ultra Low Sulfur Diesel: Diesel fuel with sulfur content less than .005% by weight. EPA diesel cannot be sold within California. EPA diesel produced in California is exported to neighboring states.


CARB Ultra Low Sulfur Diesel: Diesel fuel which meets specifications set by the California Air Resources Board (CARB). This fuel is widely available throughout California.


CARB Reformulated Gasoline (CARB RFG): An oxygenated reformulated gasoline which meets the most recent specifications set forth by the California Air Resources Board (CARB). This gasoline contains 10.0% ethanol as an oxygenate.

What is reformulated gasoline?


Reformulated gasoline (RFG) is a special blend designed to reduce harmful automotive emissions. RFG must be marketed in those areas of the United States where air quality doesn't meet the ozone requirements of the Clean Air Act Amendments. It is formulated to reduce the emissions of NOx and volatile organic compounds, and has lower benzene levels.

What is California Air Resources Board (CARB) gasoline?


CARB gasoline is a type of reformulated gasoline designed to reduce emissions. It reduces the emissions of NOx and volatile organic compounds, has lower benzene and sulfur levels, and limits the amounts of aromatic and olefinic compounds in the blends. It is required throughout the state of California


Other than price, what is the difference between regular, midgrade, and premium gasoline?

 

Gasolines are rated based on octane. In most areas of the country our regular gasoline is 87 octane, midgrade is 89 and premium is 91 – 93. If you check your owner’s manual, you’ll find the recommended level for your engine.

Why should I follow my owner’s manual and choose mid or high-octane fuel? Isn’t gas just gas?
To get the best performance out of your vehicle, you should use the octane recommended in your owner’s manual. Most vehicles do not benefit from a higher octane level than what is recommended but using a lower octane than recommended can cause engine knocking or pinging in some cars.

Does gas have an expiration date?
In general, gasoline should be used within a month of purchase. When the engine will not be used for an extended period of time, it’s best to drain the fuel tank and then run the engine until it stalls. If you choose to store gasoline, keep it in a very nearly full, tightly sealed metal container in a cool environment. Be sure to leave some room in the container to allow for some expansion. Under these conditions, the gasoline can be expected to remain of good quality for at least six months.

Is there a situation where the octane my vehicle needs would differ from the level recommended in my owner’s manual?
In general, the octane a vehicle needs aligns with the manufacturer’s recommendation. However, each vehicle is different, owing to factors such as manufacturing variability, mileage, type of operation and general condition. As a result, some vehicles may require a higher octane, particularly after an initial period of operation.  If knocking or pinging suddenly occurs, using a higher octane grade may resolve the problem.
