This law requires the California Department of Motor Vehicles to set standards for different types of vehicle fuels, like gasoline, ethanol, and natural gas. These standards should match the most current guidelines from organizations like ASTM or SAE, but can't be less strict than California state laws. For blends of gasoline and methanol, they must include a similar or higher percentage of another alcohol, like butanol, unless the EPA says otherwise. Fuels like gasoline must have a minimum antiknock index of 87, and specific standards are set for different counties in California. Each type of fuel should meet specific ASTM international standards, and if certain fuels don't have established standards, interim ones can be made by the authorities.

When calculating how much ethanol is in an ethanol-gasoline blend for fuel, you need to include the volume of any additives mixed with the ethanol, as long as these additives do not go over the limits set by the latest ASTM International standard. However, these standards cannot be less strict than California's state laws.

This law prohibits anyone from selling something as gasoline or engine fuel unless it meets certain specifications set by the law.

This law makes it illegal to sell or offer motor vehicle fuel that doesn't meet specific labeling requirements. If the fuel doesn't have a recognized brand, you must clearly label it as 'no brand' and must also prominently indicate 'not gasoline' on the label or sign. These labeling rules don't apply to fuels like kerosene, diesel, or other specified fuels. Additionally, this law doesn't apply to electricity used as vehicle fuel.

This law requires a sign or label on the inlet end of an underground storage tank's fill-pipe. The sign must be securely attached and easy to see while the tank is being filled. The size of the letters on the sign can be any size that is convenient.
