Let’s go in detail about white petrol:
In this article:
1. Definition of White Petrol
White petrol is a type of highly refined, colorless, volatile petroleum-based fuel.
- Also called naphtha or Coleman fuel in some contexts.
- It is primarily used in small engines, camping stoves, lamps, and heaters, rather than in vehicles.
- The name “white” comes from its clear, colorless appearance compared to darker fuels like diesel or kerosene.

Why white petrol is used?
• Very low boiling point: evaporates quickly and leaves minimal residue.
• High volatility: useful as a cleaning, degreasing, and extraction solvent.
• Low aromatic content: less chemically reactive than many other organic solvents.
• Good solvency for oils, waxes, and non-polar compounds.
Typical uses include laboratory extraction, cleaning mechanical parts, dry cleaning formulations, and as a lighter or stove fuel.
2. Composition of White Petrol
- Made from light hydrocarbons, mostly C5–C12 alkanes and cycloalkanes.
- Highly refined to remove impurities, sulfur, and aromatics.
- Low in viscosity and flash point compared to kerosene or diesel.
Properties:
| Property | Typical Value | Importance |
|---|---|---|
| Appearance | Colorless, transparent | Easy to distinguish from kerosene or diesel |
| Boiling Range | 30–200°C | Highly volatile, easy to ignite |
| Flash Point | ~0–40°C | Very flammable, handle with care |
| Energy Content | ~44 MJ/kg | Provides high energy for stoves and lamps |
| Odor | Mild petroleum smell | Less pungent than kerosene |
3. Uses of White Petrol
- Camping Stoves / Lanterns:
- Burns cleanly and efficiently for cooking and lighting.
- Small Internal Combustion Engines:
- Used in model airplanes, motorcycles, generators, or vintage vehicles.
- Solvent / Cleaning Agent:
- Occasionally used in labs or workshops as a degreaser or paint thinner.
- Heating Applications:
- Used in portable heaters where kerosene may be too heavy or smoky.
4. Advantages of White Petrol
- Burns cleanly with minimal soot.
- Highly volatile – easy to start in cold conditions.
- Low residue – reduces maintenance for small engines and stoves.
- Stable storage – can be stored for a few years if sealed properly.
5. Safety Precautions
- Extremely flammable – store away from sparks and heat sources.
- Vapors are toxic if inhaled in high concentration.
- Use in well-ventilated areas to prevent fire or poisoning.
- Always follow manufacturer guidelines for fuel type when using engines or stoves.
6. Difference Between White Petrol, Kerosene, and Diesel
| Feature | White Petrol | Kerosene | Diesel |
|---|---|---|---|
| Boiling Point | 30–200°C | 150–300°C | 250–350°C |
| Volatility | High | Medium | Low |
| Color | Colorless | Pale yellow | Darker brown |
| Use | Stoves, small engines, lamps | Heaters, aviation turbines | Cars, trucks, ships |
| Flammability | Very high | Moderate | Lower |
✅ Summary
- White petrol = highly refined, colorless petroleum fuel.
- Primary uses: Camping stoves, lanterns, small engines, and portable heaters.
- Properties: Highly volatile, clean-burning, low residue, and high energy content.
- Safety: Extremely flammable, toxic if inhaled, must be handled carefully.
- Distinction: Lighter and more volatile than kerosene or diesel; burns cleaner.
💡 Tip:
White petrol is ideal for portable and small combustion systems where quick ignition, clean burn, and low soot are important, unlike heavier fuels for cars or airplanes.
