In 2023, about 0.33 billion barrels (13.73 billion gallons) of fuel ethanol were blended into the 3.26 billion barrels (137.11 billion gallons) of finished motor gasoline consumed.
Do you have any numbers that show it isn’t 10% or are you just trying to give me a hard time? The actual numbers, directly from the EIA, are 10%.
That math is meaningless to the discussion of whether or not every single gas pump with a “May contain up to 10% ethanol” sticker actually has exactly 10% ethanol.
It’s “up to 10%”. Who knows what the actual number is.
It’s 10%.
The Renewable Fuel Standard, createdy by the Energy Policy Act of 2005 mandates an increasing quantity of ethanol be produced and mixed into gasoline. That is now at 36 billion gallons of ethanol as of 2022.
However, it is capped at 10% to ensure engines can safely use it. So, with the US annual consumption of gasoline at 137 billion gallons, we hit the 10% cap and put 13 billion gallons of ethanol into gasoline.
It’s 10%.
The very first paragraph in your last link straight up says the actual amount varies.
That paragraph says the amount of denaturant in ethanol varries. That is normally 2%, but can vary.
That very first paragraph has ethanol numbers, and those numbers are…10%:
Do you have any numbers that show it isn’t 10% or are you just trying to give me a hard time? The actual numbers, directly from the EIA, are 10%.
Very first sentence. ‘About 10%’ is not the same as 10%, and ‘Most’ means not all gasoline is ‘about 10%’. You can still buy ethanol free gasoline.
That’s why it’s phrased as “May contain up to 10% ethanol.” Without testing a sample you won’t know exactly how much ethanol it contains.
That’s correct, using EIA’s numbers, it’s actually 10.12% ethanol in 2023!
Math: 0.33b / 3.26b -> 10.12%
That math is meaningless to the discussion of whether or not every single gas pump with a “May contain up to 10% ethanol” sticker actually has exactly 10% ethanol.
There’s a reason that absolute wording isn’t used. Here’s another instance of the government using ‘up to 10%’
