Petroleum liquid dyes are solvent soluble colorants used to provide vibrant, stable colouration to fuels, oils, lubricants, waxes and other hydrocarbon based products. Their excellent solubility, high colour strength and uniform dispersion in petroleum and solvent systems, make them suitable for products that can be easily identified, branded, used for leak detection and industrial processing applications. Petroleum liquid dyes are applied in gasoline, aviation fuel, kerosene, mineral oils and lubricants due to their good stability and reliable performance.
Mixed easily in petroleum and solvent-based systems.
Bright and vibrant shades with high colour intensity.
Improves product identification and differentiation.

Application is done by metering pump to ensure accurate and consistent dosing.

Our petroleum liquid dyes are suitable for all types of gas oil. For sensitive applications like aviation fuel, the key parameter is the insoluble content, which must be lower than 0.5%.

For lubricants, dosage levels are generally much higher than for gas oil. Typical dosage levels for lubricants are in the range of 150 to 200 ppm whereas for gas oil the range is between 10 ppm to 50 ppm. Please note: Actual dosages for gas oil are prescribed by the relevant government authority which also determines the specific dye or combination of dyes to be used for each fuel type.
Fuel and lubricant producers rely on petroleum liquid dyes because they dissolve cleanly into hydrocarbon products, giving each grade a distinct, stable colour for identification. Colour isn’t decoration here. It’s how a refinery, distributor or regulator tells products apart at a glance.
Petroleum liquid dyes are solvent-soluble colourants made specifically for gasoline, aviation fuel, kerosene, mineral oils and lubricants. Alliance Organics manufactures this range for exactly that kind of spec-driven use, where a dye either performs to standard or gets rejected.
You’ll learn why solubility matters so much in this category, how dosing works across different fuel types, which shades are available, and what to check before you commit to a supplier.
Solubility matters because a dye that doesn’t fully dissolve becomes a liability, not a colourant. Undissolved particles clog filters, distort readings and fail the uniform colour a product spec demands.
Petroleum liquid dyes are formulated to mix completely into petroleum and solvent systems. They hold their shade through storage and handling without settling out or clouding the product over time.
That reliability is what makes them useful beyond branding. Grade differentiation and leak detection across pipelines and storage systems both depend on a dye staying dissolved and consistent, batch after batch.
What full solubility protects against:
A petroleum liquid dye only does its job if it stays fully dissolved from tank to end use.
Petroleum liquid dyes are applied through a metering pump, which keeps dosing accurate rather than left to manual estimation. Dosage levels vary sharply by product type.
Lubricants generally need a heavier dose, usually in the 150 to 200 ppm range. Gas oil runs much lighter, typically between 10 and 50 ppm, since even a small volume of dye colours a large batch of fuel.
Aviation fuel demands the most caution of all. Insoluble content has to stay below 0.5%, because even a trace of undissolved dye can affect fuel system performance in a way regulators won’t accept.
Typical dosage by product:
Product | Typical dosage |
Lubricants | 150 to 200 ppm |
Gas oil | 10 to 50 ppm |
Aviation fuel | Insoluble content below 0.5% |
Gas oil dosage and dye combinations are usually set by the relevant government fuel-marking authority, not decided independently by supplier or buyer.
Correct dosing depends on the product type and, for gas oil, on regulatory specification rather than guesswork.
Alliance Organics supplies a petroleum liquid dye range covering the shades fuel and lubricant producers commonly need across regulatory and branding use cases.
The range includes Solvent Yellow 107, 124 and 126, Solvent Orange 98, Solvent Red 19E and 164, Solvent Blue 79, 79B and 98, and Solvent Green 33. Each shade suits gasoline, aviation fuel, kerosene or lubricant applications, tested for solubility and colour strength before dispatch.
That spread lets producers standardise on one consistent shade, whether they’re marking fuel for regulatory identification or colouring a lubricant line for brand differentiation.
A wide, tested shade range means one supplier can cover both compliance marking and brand-level colour needs.
Fuel and lubricant producers rely on petroleum liquid dyes because full solubility, correct dosing and a tested shade range are what let colour actually function as identification, not just branding.
Key takeaways:
Need a petroleum liquid dye tested for your product line? Alliance Organics can share solubility and colour strength data for the shade you’re evaluating.
They colour gasoline, aviation fuel, kerosene, mineral oils and lubricants for product identification, brand differentiation and leak detection. Producers use them wherever a product needs a distinct, stable colour rather than decoration.
They’re applied through a metering pump, which allows accurate and consistent dosing rather than manual mixing. This keeps colour strength uniform across an entire production run.
Lubricants generally need 150 to 200 ppm, while gas oil needs far less, typically 10 to 50 ppm. Aviation fuel has a stricter rule: insoluble content must stay below 0.5%.
The relevant government authority typically prescribes both the dye combination and the dosage level for each fuel type. Suppliers and buyers work within that specification rather than setting it themselves.
Yes, provided the insoluble content stays below 0.5%, a stricter threshold than most other petroleum products require. This is why solubility testing matters more in aviation-grade dye than almost anywhere else.
