What Kind of Gas Does A Lexus Require?
Lexus and Fuel: What’s the Right Choice for Your Vehicle?
If you own or are considering a Lexus, you’ve likely wondered: Do all Lexus models require premium gas? The short answer—most do, but not all. Lexus is known for its high-performance engines, and many models are designed to run on 91-octane premium fuel for optimal efficiency and longevity. However, a few models in the lineup can safely run on 87-octane regular unleaded gas without compromising performance.
Which Lexus Models Require Premium Gas?
Most Lexus vehicles, particularly those with turbocharged or performance-focused engines, require premium gas. If you’re driving any of these models, be sure to fill up with 91-octane or higher:
- Lexus IS (IS 300, IS 350, IS 500)
- Lexus LS (LS 500, LS 500h)
- Lexus RC (RC 300, RC 350, RC F)
- Lexus LC (LC 500, LC 500h)
- Lexus RX (RX 350, RX 450h)
- Lexus GX (GX 460)
- Lexus LX (LX 600)
These models have high-compression engines designed to extract maximum power and efficiency from premium fuel. Using lower-grade gasoline could result in reduced performance and potential long-term engine damage.
Which Lexus Models Can Use Regular Gas?
If you’re looking for a Lexus that runs on 87-octane fuel, there are a few options in the lineup:
- Lexus ES (ES 250, ES 350, ES 300h)
- Lexus UX (UX 250h)
- Lexus NX (NX 250)
These models have engines tuned to run efficiently on regular fuel, making them a great choice for drivers who want a balance between luxury and affordability at the pump.
Why Does Premium Fuel Matter for Certain Lexus Models?
Premium gasoline isn’t just a luxury—it’s a necessity for high-performance Lexus engines. Here’s why:
- Better Engine Performance – High-octane fuel helps prevent engine knocking, a condition where the air-fuel mixture ignites prematurely, leading to reduced efficiency and possible engine damage.
- Maximized Fuel Efficiency – Lexus engineers design premium-fuel models to deliver optimal fuel economy when using the recommended octane level.
- Longer Engine Life – Premium fuel burns cleaner, keeping the engine’s internal components in better shape over time.
What Happens If You Use Regular Gas in a Premium Lexus?
We get it—premium fuel costs more, and it’s tempting to save a few cents per litre. But if your Lexus requires premium gas, using regular 87-octane could lead to:
- Reduced Performance – Your Lexus may feel sluggish, with slower acceleration and lower power output.
- Lower Fuel Efficiency – You might end up visiting the pump more often, cancelling out any savings.
- Potential Engine Damage – Over time, using the wrong fuel grade can cause engine knocking, leading to costly repairs.
- Warranty Issues – Some Lexus warranties require the use of premium fuel. Using regular gas may void certain coverage protections.
