California AB 2046: The Common-Sense Fuel Bill That Took 49 Other States Zero Effort

California AB 2046: The Common-Sense Fuel Bill That Took 49 Other States Zero Effort

California is the only state in the country where you cannot legally install an E85 fuel conversion kit on your car. While drivers in Texas, Florida, Ohio, and every other state already have access to a fuel option that costs $1.50 to $2.00 less per gallon than conventional gasoline, California's regulatory framework has quietly blocked the technology for years — with no EPA-level objection and zero opposition when it finally came up for a vote. This article breaks down what AB 2046 does, why it matters with California gas prices north of $6.00 per gallon, and exactly how to push it across the finish line in the State Senate.

It took a Stockton Democrat named Rhodesia Ransom to finally drag Sacramento toward the obvious.

Assembly Bill 2046, the Access to Affordable Gas Act, passed the Assembly floor on a 59-0 vote with no debate and no opposition. None. The bill now heads to the California State Senate, where it will need to clear committee and earn Governor Newsom's signature before it becomes law. If it does, California drivers will finally have a legal pathway to convert standard gasoline vehicles into flex fuel vehicles capable of running on E85, regular gasoline, or any blend of the two.

What AB 2046 Actually Does

The bill is straightforward. Under current California law, any device that modifies a vehicle's fuel system needs approval from the California Air Resources Board before it can be sold or installed. CARB has never approved an E85 flex fuel conversion kit. Not once. That means kits that carry full U.S. Environmental Protection Agency approval, kits that are legal and in use across the entire rest of the country, are effectively banned in California.

AB 2046 would exempt EPA-approved E85 conversion kits from the CARB approval requirement. It does not mandate anything. It does not force drivers to convert. It does not force automakers to change a single bolt. It simply legalizes a voluntary, one-time installation that gives drivers a choice at the pump they have never had.

The kits themselves generally run between $600 and $800, and total cost including installation stays under $1,000. Supporters of the bill estimate a payback period of less than one year given the price difference between E85 and conventional gasoline.

Why This Bill Matters at $6.00 Per Gallon

We covered California's fuel price crisis in detail in our Pump Prices 2026-2027 analysis. The short version: the Phillips 66 Wilmington closure and the Valero Benicia shutdown wiped out roughly 17% of the state's refining capacity. California's gasoline market is isolated from the rest of the country because CARB requires a special low-emission blend that most other states do not use. There are no pipelines bringing cheaper fuel from the Gulf Coast or Midwest. State taxes, LCFS charges, and cap-and-trade costs add roughly $0.90 to $1.40 per gallon on top of everything else.

The result: California drivers are paying north of $6.00 per gallon right now, pushed even higher by the Iran-Israel conflict rattling global oil markets. The national average sits comfortably in the mid-$3.00 range.

E85 is consistently priced $1.50 to $2.00 less per gallon than conventional gasoline across California. At a Pearson Fuels station in Tracy earlier this year, drivers filled up for $1.85 per gallon during a promotion. Even at regular E85 pricing, the savings are substantial. California already has over 450 E85 stations operating statewide, with 69 new stations added in 2025 alone. The infrastructure is not hypothetical. It exists.

Yes, E85 contains less energy per gallon than gasoline, roughly 27% less according to the U.S. Department of Energy, so fuel economy drops. But when E85 is $1.50 to $2.00 cheaper per gallon, the math still works in the driver's favor for cost per mile. And E85 carries an octane rating of 100 to 105, compared to 87 to 93 for pump gasoline, which opens up efficiency and performance characteristics that are well understood by anyone who has spent time around motorsport.

Assemblymember Ransom and the 59-0 Vote

Rhodesia Ransom represents California's 13th Assembly District out of Stockton. For those of us in the Sacramento region, she is right in our backyard. And she is pushing legislation that should have been a non-issue a decade ago.

The 59-0 vote with zero opposition tells you everything you need to know about how reasonable this bill is. Twenty members did not vote, but not a single one voted against it. Even CARB acknowledged in a letter to the Legislature that E85 conversion kits have the potential to deliver cost savings for California drivers. When the regulatory agency whose approval process created the bottleneck in the first place concedes the point, you know the argument is over.

Ransom framed AB 2046 as a direct response to constituent frustration. Working families in the Central Valley and across the state are watching gas prices climb while every other state in the country has access to a cheaper alternative. Her bill does not tear down CARB's authority across the board. It carves out a narrow, sensible exception for a proven technology that the EPA has already vetted.

France has converted approximately 260,000 vehicles using similar aftermarket kits. Brazil's flex fuel market dwarfs anything in the United States. The technology is not experimental. California is simply the last one to the table.

What Needs to Happen Next in the State Senate

AB 2046 has cleared the Assembly. It now moves to the California State Senate, where it will need to pass through committee, likely the Senate Energy, Utilities and Communications Committee, before reaching a full Senate vote. If it clears the Senate, it goes to Governor Newsom's desk.

This is the part where momentum matters. A 59-0 Assembly vote is a strong signal, but bills can stall in the Senate, get amended into something unrecognizable, or simply run out of clock. If you think California drivers deserve the same fuel choices that drivers in Texas, Florida, Ohio, and every other state already have, now is the time to say so.

Sample Letter You Can Copy and Send

Subject: Support AB 2046, the Access to Affordable Gas Act

Dear Senator [Name] / Governor Newsom,

I am writing to ask for your support of Assembly Bill 2046, the Access to Affordable Gas Act, authored by Assemblymember Rhodesia Ransom. This bill would allow California drivers to legally install EPA-approved E85 conversion kits, giving them a voluntary, affordable fuel option that is already legal in all 49 other states.

California drivers are paying over $6.00 per gallon for gasoline while the national average remains in the mid-$3.00 range. E85 is consistently priced $1.50 to $2.00 less per gallon than conventional gasoline, and the state already has over 450 E85 fueling stations. AB 2046 does not mandate anything. It simply removes a regulatory barrier that prevents California drivers from accessing a proven, federally approved technology.

The bill passed the Assembly on a 59-0 vote with no opposition. Even CARB has acknowledged the potential cost savings of E85 conversion kits. This is common-sense legislation that delivers real relief at the pump.

I respectfully ask that you support AB 2046 and help bring California in line with the rest of the country on fuel choice.

Sincerely,
[Your Full Name]
[Your Address]

Verdict

AB 2046 is not complicated legislation. It does not reinvent anything. It just stops California from being the only state that tells its drivers they cannot have an option that 49 other states already provide. The conversion kits cost under $1,000 installed, pay for themselves inside a year at current price spreads, and run on fuel that is already available at more than 450 stations statewide. Assemblymember Ransom got 59 colleagues to agree without a single dissent. The Senate and the Governor should do the same.
