Do luxury cars need premium gas? Learn why INFINITI vehicles and other luxury models are engineered for higher octane fuel and how it protects performance and value.
When you drive a luxury vehicle like an INFINITI, you’re stepping into a world of precision engineering, refined comfort, and elite performance. But to keep that elevated experience going strong, you need to pay attention to the type of fuel you put into your vehicle.
So, why do luxury cars need premium gas? And more importantly, do luxury cars really require it? The short answer is yes — and for good reason. Premium fuel helps protect your vehicle’s performance, longevity, and resale value, especially when you’re driving something as finely tuned as an INFINITI.
At the gas station, you’ll find multiple options at the pump. Each grade of gasoline is assigned an octane rating, which refers to the fuel’s ability to resist “knocking” — a type of premature combustion that occurs when fuel ignites before your spark plug fires.
Here’s a breakdown:
High-performance luxury engines, like those in many INFINITI models, operate with higher compression ratios or turbochargers. These designs require higher octane fuel to prevent knocking and ensure the combustion process is controlled, efficient, and smooth. Using a lower octane than what your car recommends can lead to engine issues, diminished performance, and long-term damage.
Using regular gas in a luxury car that requires premium is like wearing running shoes to a black-tie event — it technically works, but it completely undercuts the experience your car was built to deliver.
Here’s what can happen if you skip premium:
Absolutely — especially if you’re driving a performance-focused vehicle like an INFINITI. These engines are built to deliver a balance of power and refinement, and they rely on high-octane fuel to do so consistently.
When you use premium gas:
Think of it this way — investing in premium fuel is a small cost compared to the price of a luxury vehicle. But the benefits are long-lasting and impactful, both for your car’s health and your driving satisfaction.
In rare situations, like a remote gas station without premium options, using a lower octane temporarily won’t destroy your engine. However, it’s not a habit you want to form. Your vehicle’s computer may try to compensate by adjusting timing or performance, but this often results in lower efficiency, reduced power, and increased engine stress. As soon as possible, return to premium.
Always follow the manufacturer’s guidelines. For INFINITI owners, those guidelines typically call for premium unleaded fuel of 91 octane or higher.
