California law requires every gas station in the state to provide free air and water to customers during operating hours. The rule lives in Business and Professions Code Section 13651, and it covers passenger cars and commercial vehicles with an unladen weight of 6,000 pounds or less.1California Legislative Information. California Business and Professions Code Section 13651 That is nearly every personal vehicle on the road. The station also has to make a tire pressure gauge available.
What You Have to Buy to Qualify
You are entitled to free air and water once you become a “customer.” The statute frames the requirement around people “who purchase motor vehicle fuel,”1California Legislative Information. California Business and Professions Code Section 13651 but the definition of customer reaches further: anyone who buys any product sold on the premises qualifies, including items unrelated to your car.2California Department of Food and Agriculture. California Business and Professions Code Division 5 – Chapter 14.5 Service Stations 13650-13660 A bottle of water or a pack of gum from the attached convenience store counts. There is no minimum purchase amount and no gallon threshold.
If you walk up to the air machine without buying anything, you are not a customer under the law, and the station can charge you whatever it charges anyone else. Coin-operated machines typically run $1.00 to $3.00. So if you need air but weren’t planning to fuel up, grab something small inside first and keep the receipt.
One boundary worth knowing: the free water is meant for radiators, batteries, and similar automotive purposes. Washing your car is not covered.
What the Station Has to Provide
Every service station selling gasoline or other motor vehicle fuel to the public falls under the law.3California Legislative Information. California Business and Professions Code Section 13650 The equipment must be functional and accessible during operating hours, and that means working compressed air, water, and a working tire pressure gauge. Coin-operated air machines are still allowed, but the station has to give qualifying customers a way to use them for free. In practice, an attendant activates the machine or hands out a token after you show a receipt.
A sign has to be posted on or near the air and water equipment telling customers about the free-air right and giving a toll-free complaint number to call.2California Department of Food and Agriculture. California Business and Professions Code Division 5 – Chapter 14.5 Service Stations 13650-13660 Missing signage is itself a violation.
Standalone electric vehicle charging stations are not covered, because the statutory definition of service station requires the sale of gasoline or other motor vehicle fuel.3California Legislative Information. California Business and Professions Code Section 13650
When the Air Machine Is Broken
Broken equipment is the most common reason a station fails to provide air. The law gives stations a repair window: no citation will be issued if the equipment is fixed within 10 working days of the initial inspection.1California Legislative Information. California Business and Professions Code Section 13651 That grace period does not excuse a station that lets a compressor sit broken for weeks. Once the 10 working days close, enforcement is back on the table.
If you pull up to a dead machine, tell the attendant. That conversation sometimes gets faster results than a formal complaint, and it puts the station on notice.
How to File a Complaint
If a station refuses to give you free air or water after you have bought something, or if the equipment has been down for an extended period, you can file a complaint with the California Department of Food and Agriculture’s Division of Measurement Standards (DMS). Two ways to do it:
- By phone at (800) 356-7057.4California Department of Food and Agriculture. DMS – How to File a Consumer Complaint
- Online or by mail using the Air and Water Complaint Form on the DMS website. The mailing address is Division of Measurement Standards, 6790 Florin Perkins Road, Suite 100, Sacramento, CA 95828.5California Department of Food and Agriculture Division of Measurement Standards.

Day-to-day inspections are done by county weights and measures officials working under DMS authority.6California Department of Food and Agriculture. Division of Measurement Standards When a complaint comes in, an inspector can investigate and issue a citation directly.
Fines Stations Face
Two layers of penalties apply. The Division of Measurement Standards can collect a $250 fine per valid complaint against a station unless the station challenges the citation in court.2California Department of Food and Agriculture. California Business and Professions Code Division 5 – Chapter 14.5 Service Stations 13650-13660
Individuals who personally violate the law, whether a manager setting policy or an employee acting alone, face infractions with escalating fines: $100 for a first offense, $200 for a second, and $500 for each subsequent offense.2California Department of Food and Agriculture. California Business and Professions Code Division 5 – Chapter 14.5 Service Stations 13650-13660
The dollar amounts are modest on their own, but the combination of per-complaint fines and personal infractions is usually enough to bring a station into line after a first citation.
