How Fuel Quality Is Measured and Why Measurement Matters

Proper assessment of fuel quality is not just about knowing the octane or cetane number of gasoline or diesel. It is a combination of multiple physical and chemical parameters, which are controlled in laboratories, during transport, and even at fuel stations.

How Using Low-Quality or Incorrect Octane Fuel Affects Your Vehicle

The market often contains fuel that does not meet established standards. Using fuel with incorrect octane or low-quality compounds can significantly damage your vehicle’s engine and exhaust system. This increases operational costs and has a negative impact on the environment.

Here is a list of the main risks associated with using low-quality or non-compliant octane fuel:

Engine and System Component Damage:

  • High sulfur or water content in fuel causes internal corrosion.
  • Rapid damage to fuel filters, injectors, and other system components.

Engine Knocking and Loss of Power:

  • Low octane ratings (RON/MON) cause engine knocking, which reduces power and limits engine performance.
  • Over time, this accelerates wear of engine components.

Exhaust and Catalytic Converter Damage:

  • High concentrations of aromatic and polyaromatic hydrocarbons increase exhaust emissions and reduce the lifespan of the catalytic converter.
  • This affects not only the technical condition of the vehicle but also contributes to environmental pollution.

How to Avoid These Problems? Choose high-quality fuel from a reliable source — consider octane ratings, brand technical standards, and continuous quality control. This is the only way to protect your vehicle and ensure its long-lasting, safe operation.
