Fuel ratings: The Federal Trade Commission (FTC) is moving forward with new automotive fuel ratings for ethanol-gasoline blends.

The automotive fuel ratings, first developed in 1979, are intended to “help purchasers identify the correct fuel for their vehicles,” the agency wrote.

Under the new rules, ethanol will be subject to new rating, certification and labeling requirements, the FTC noted.

The rules go into effect on July 14.


The new rules include fuel labeling for blends of more than 10% ethanol, along with changes to octane rating labeling. 


Here is the document:
