Usage of 110-Octane Gasoline (RON)
Gasoline with an octane rating of 110 (RON) is a specialized high-performance fuel designed for engines under extreme load conditions. Its key feature is maximum knock resistance, critical for high-performance tuned engines.
Where is 110-Octane Gasoline Used?
🔹 Drag Racing
- Top Fuel (nitromethane) and pure gasoline classes — used in categories like "Super Stock".
- Naturally aspirated V8 drag cars (e.g., Chevrolet Camaro, Ford Mustang) with compression ratios 14:1 and higher.
Examples:
- Dragsters with Hemi 426 engines (15:1 compression)
- Pro Mod gasoline-class cars (no nitromethane)
🔹 Circuit Racing
- NASCAR (previously used Sunoco 110 equivalent).
- GT and Touring race cars with high-RPM engines (e.g., Porsche 911 GT3 R).
🔹 Tuned & Performance Vehicles
- Naturally aspirated engines with 13:1–16:1 compression.
- Turbocharged engines with 2.0–3.0 bar boost (requires ECU remapping).
Examples:
- Mazda RX-7 (13B-REW) with modified rotary engines.
- Subaru Impreza STI (9.5:1 compression + 2.5+ bar boost).
🔹 Race Motorcycles
- MotoGP prototypes — during testing.
- Drag bikes (e.g., turbocharged Suzuki Hayabusa).
🔹 Specialized Vehicles
- Rally trucks (Dakar, Baja 1000).
- Race quads and buggies.
Engine Requirements for 110-Octane
| Engine Type | Compression Ratio | Key Requirements |
|---|---|---|
| Naturally Aspirated | 13:1 – 16:1 | Forged pistons/valves required. |
| Turbocharged | 8.5:1 – 10:1 | Cylinder pressure equivalent to 14:1+ due to boost. |
| Rotary (Wankel) | 9.5:1 – 11:1* | *Higher effective compression from design. |
🔸 Required Modifications
- Pistons/rods — forged (to prevent failure).
- Ignition system — upgraded coils + cold spark plugs.
- Fuel system — high-flow injectors/pumps (110-octane fuel often has low volatility).
Can You Use 110-Octane in Stock Cars?
🚫 No!
- No power gains without engine modifications; may combust inefficiently.
- Damage risks:
- Spark plug/valve deposits (slow combustion).
- Catalytic converter/O2 sensor degradation.
✅ Exceptions:
- Vehicles with adaptive ECUs (e.g., some Ferrari/Porsche models).
Conclusion
🔹 110-octane is for:
- Race/tuned engines with extreme compression or boost.
- Drag/circuit racing where nitromethane is prohibited.
🔹 Not for street cars — requires professional tuning.
