Using the correct octane rating fuel is essential for keeping your vehicle running smoothly and efficiently

The octane number indicates how well fuel resists premature ignition under pressure

Premature ignition happens when the fuel-air blend detonates from heat and compression instead of the spark plug’s timed ignition

This can cause damage over time and reduce engine performance

Most consumer vehicles have engines calibrated specifically for regular-grade fuel, commonly rated at 87

These engines have compression ratios and ignition timing calibrated for this level of resistance to knocking

Upgrading to premium fuel in a standard engine offers no measurable gains in power, mileage, or carbon reduction

You pay extra for no tangible improvement in operation or efficiency

Falling below the recommended octane level can trigger serious engine issues

Turbocharged, supercharged, and high-compression engines function under extreme thermal and mechanical stress

Higher octane fuel is mandatory to avoid destructive detonation in high-stress engines

Using under-rated fuel may cause power loss, increased fuel consumption, and in worst cases, bent rods or damaged pistons

Advanced ECUs can detect knock and اتوسرویس داوود retard ignition timing to protect the engine, but this sacrifices power and increases stress

Always check your owner’s manual to see what octane rating your vehicle manufacturer recommends

Many vehicles display the required octane rating near the fuel filler opening

Adhering to OEM fuel recommendations preserves optimal performance and protects warranty coverage

Even with the right octane, poor fuel quality can harm your engine

Even if you use the correct octane rating, low quality fuel with contaminants can still cause problems

Avoid gas that smells unusual or has been stored for extended periods — it may be degraded or contaminated

Choosing the correct octane isn’t about overspending — it’s about precision matching

It is about matching the fuel to your engine’s design

The right fuel prevents damage, sustains power output, and reduces long-term costs by minimizing wear and wasted fuel
