The Lexus GX is engineered to perform optimally using premium-grade gasoline. While the vehicle’s engine is designed to function with regular unleaded fuel, utilizing fuel with a higher octane rating, as specified for premium gasoline, is generally recommended by the manufacturer for achieving peak performance and efficiency. Using regular gasoline will not damage the engine.
Employing premium gasoline in vehicles designed for its use can potentially enhance engine responsiveness and overall driving experience. Historically, luxury vehicles often feature engines optimized for higher octane fuels to deliver the performance characteristics expected by their owners. The recommendation to use premium fuel reflects this performance optimization, although the actual benefit may vary depending on driving conditions and individual usage patterns.
