How Much Protein Is in Gasoline?
None—gasoline contains 0 grams of protein. Gasoline is a petroleum-derived fuel composed of hydrocarbons, not biological macromolecules like proteins, so it offers no nutritional value and should never be ingested.

What Gasoline Is Made Of
Gasoline is a refined blend of hydrocarbons—primarily alkanes, cycloalkanes, and aromatic compounds—optimized for combustion in internal combustion engines. These molecules contain carbon and hydrogen, sometimes with trace impurities from crude oil, but they do not include amino acids or peptide bonds, the fundamental building blocks of proteins.
Why Asking About Protein in Gasoline Is a Category Error
Proteins are nitrogen-containing biological polymers formed from amino acids and found in foods and living organisms. Gasoline, by contrast, is a non-biological, energy-dense chemical mixture designed to burn cleanly and efficiently. Nutritional concepts such as calories, protein, fat, or carbohydrates do not apply to fuels like gasoline.
Trace Compounds and the “Almost Zero” Caveat
While crude oil can contain nitrogen- and sulfur-bearing molecules, modern refining aims to remove these to protect engines and reduce emissions. Any nitrogen present in finished gasoline is at trace levels and does not constitute protein. Gasoline is neither analyzed nor labeled for nutrition, because it is not a consumable product.
Key Reasons Gasoline Has No Protein
The following points explain, from a chemistry perspective, why protein is absent from gasoline and why the concept does not translate to fuels.
- Proteins require nitrogen-rich amino acids and peptide bonds; gasoline is a mixture of hydrocarbons without these features.
- Refining processes (distillation, cracking, hydrotreating) remove or transform complex, reactive compounds that could include heteroatoms like nitrogen.
- Any biological material contaminating crude would be destroyed, transformed, or separated during refining.
- Regulatory and industry specifications target performance and emissions, not nutritional content; gasoline is not a food substance.
Taken together, these factors show that gasoline’s composition is chemically incompatible with the presence of protein.
Safety Considerations
Gasoline is toxic. Ingestion can cause chemical pneumonitis if aspirated, and inhalation of vapors can be harmful. If someone swallows gasoline, do not induce vomiting; seek medical help immediately. In the United States, contact Poison Control at 1-800-222-1222 or use their online tool; elsewhere, call local emergency services.
How Protein Is Measured—and Why It Doesn’t Apply Here
Common protein assays in food science (such as Kjeldahl or Dumas) estimate protein by measuring total nitrogen. Applying these methods to gasoline would yield results near zero, with any detected nitrogen reflecting trace non-protein compounds. That underscores the mismatch between nutritional metrics and petroleum products.
Summary
Gasoline contains 0 grams of protein. It is a hydrocarbon fuel, not a biological or nutritional substance. Any nitrogen present is at trace levels and not in the form of protein. Gasoline should never be ingested and is evaluated for engine performance and safety, not nutrition.
Does gasoline have protein in it?
There is no protein in gasoline, so there is 0 protein no matter what the amount of gasoline is.

How healthy is gasoline?
Repeated exposure to very high levels of gasoline can cause poor appetite, weakness, and even brain or kidney damage. Gasoline contains benzene and other additives that may cause future health problems after repeated, high-level exposures.
What is the nutritional value of gasoline?
Gasoline is not a food and has no nutritional value; it is a toxic and dangerous substance, not meant for consumption, and ingesting it can be fatal. While a gallon of gasoline contains about 31,000 food Calories (kilocalories) of chemical energy, the human body cannot metabolize this energy because it lacks the necessary digestive pathways.
Why Gasoline Has No Nutritional Value
- Toxic Composition: Opens in new tabGasoline is made from hydrocarbons that are harmful and not digestible by humans.
- Metabolic Incompatibility: Opens in new tabFor energy to be useful, the body must be able to break down the substance into usable nutrients like fats, carbohydrates, or proteins, which gasoline does not provide.
The Energy Content of Gasoline
- Kilocalories: A gallon of gasoline contains approximately 31,000 food Calories (also known as kilocalories).
- Carbohydrates and Sugars: While some sources list carbohydrate and sugar content for gasoline, this refers to the chemical composition and has no bearing on its nutritional value for humans.
Dangers of Ingesting Gasoline
- Health Hazard: Ingesting gasoline is extremely harmful.
- Seek Medical Attention: If gasoline is ingested, immediate medical attention is required.
