Can a Lamborghini use 95 octane petrol?

Lamborghini vehicles cannot use 95 octane petrol; all Lamborghini models require 98 octane fuel. As a supercar manufacturer, Lamborghini equips its vehicles with large-displacement, multi-cylinder high-performance engines, and using petrol with too low an octane rating may cause engine knocking. Below are detailed explanations:

The relationship between octane rating and anti-knock properties:

Higher octane petrol has better anti-knock properties. When the air-fuel mixture is injected into the cylinder, the piston compresses the mixture as it moves upward. As pressure increases, temperature rises. If the petrol's anti-knock quality is insufficient, combustion may begin before the spark plug ignites, leading to uncontrolled combustion—commonly known as knocking. Knocking not only reduces engine performance but can also cause engine damage.

Choosing the right octane rating for your vehicle:

92 octane petrol is suitable for basic, less technologically advanced vehicles. 95 octane petrol works for the vast majority of cars. 98 octane petrol is designed for turbocharged engines and vehicles with high compression ratios, being compatible with most high-performance models.

From a mechanical perspective, Lamborghini’s high-performance engines are finely tuned for 98 RON fuel. While 95 RON might work occasionally, the engine’s knock sensors will retard ignition timing to prevent damage, sacrificing power. For a car engineered to deliver extreme performance, compromising on fuel quality undermines its purpose. Always prioritise the manufacturer’s guidelines to avoid costly repairs.

Lamborghini models, including the Huracán and Aventador, are designed to run on high-octane petrol, typically 98 RON or higher. While some modern Lamborghinis may tolerate 95 RON fuel in emergencies, using it regularly is not recommended. Lower-octane fuel can cause engine knocking, reduced performance, and potential long-term damage due to the high-compression engines in these supercars.

For optimal performance and engine longevity, always follow the manufacturer’s recommendation. Lamborghini’s advanced engine management systems may adjust timing to mitigate issues, but this can still result in lower power output. If 98 RON is unavailable, consider using an octane booster as a temporary solution.

Key considerations:

1. Performance impact: 95 RON may reduce horsepower and throttle response.
2. Engine health: Prolonged use risks premature wear or knocking.
3. Warranty implications: Deviating from recommended fuel could void coverage.

Stick to premium fuels like Shell V-Power or BP Ultimate for peak performance.
