What gas does a 2018 Lexus IS300 take?
The 2018 Lexus IS300 requires premium unleaded gasoline, typically 91 octane or higher. This is the recommended fuel type for this vehicle according to the manufacturer's specifications.
Detailed Answer
The 2018 Lexus IS300 is a luxury compact sedan produced by the Toyota-owned Lexus brand. This particular model is powered by a 2.0-liter turbocharged four-cylinder engine that generates 241 horsepower. To ensure optimal performance and fuel efficiency, Lexus recommends using premium unleaded gasoline with a minimum octane rating of 91.
Using the recommended premium fuel is important for several reasons:
- The engine is designed to take advantage of the higher octane rating, which helps prevent knocking or pinging during combustion.
- Premium fuel has a higher resistance to premature ignition, allowing the engine to operate at higher compression ratios for increased power output.
- Using a lower octane fuel than recommended can lead to reduced fuel economy, decreased engine performance, and potential long-term damage to the engine components.
It's worth noting that while the 2018 Lexus IS300 can technically run on regular 87 octane gasoline, doing so is not recommended by the manufacturer and may void the vehicle's warranty. For the best performance, fuel efficiency, and long-term engine health, Lexus advises owners to always use premium unleaded fuel with a minimum octane rating of 91.
What happens if I use regular gas in a Lexus is?
Use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, damage to the engine may occur and which could void the vehicle warranty.
