The 2026 Lexus LX runs a twin-turbocharged 3.4-liter V6 requiring premium fuel with a recommended octane rating of 95 or higher.

Drivers in Riverside, Corona, Moreno Valley, and the surrounding Inland Empire looking to own a 2026 Lexus LX can view current LX inventory at Lexus of Riverside before scheduling a service consultation or test drive.
Fuel Requirements for the 2026 Lexus LX
Both the LX 600 and LX 700h require premium unleaded fuel. Lexus specifies a recommended octane rating of 95 or more. Using lower-octane fuel can reduce engine performance and may affect long-term engine health on this twin-turbo platform. The LX 600 holds 21.14 gallons, while the LX 700h carries a smaller 17.97-gallon tank due to the hybrid battery's positioning in the rear floor structure.
2026 Lexus LX Recommended Service Schedule
Lexus follows a time-and-mileage-based maintenance schedule. The intervals below reflect standard Lexus recommendations for the LX platform.

Regular maintenance is essential for keeping your Lexus performing at its peak. The following schedule outlines the required intervals for oil changes, filter replacements, fluid inspections, and other vital services to ensure the longevity of your vehicle, whether equipped with the twin-turbo V6 or the LX 700h hybrid powertrain.

LX 700h Hybrid-Specific Maintenance
The LX 700h uses a nickel-metal hydride battery with a nominal voltage of 288V and 240 battery cells. Unlike lithium-ion systems, nickel-metal hydride batteries in Lexus hybrid vehicles have a long service history and generally do not require scheduled replacement within typical ownership cycles.
owners should note:
- The hybrid battery is located under the luggage compartment (two-row) or beneath the third-row seat (three-row), and proper airflow to those areas should be kept clear
- The LX 700h's waterproof battery tray includes a water sensor that alerts the driver via the meter display if water is detected, particularly relevant for the 27.5-inch fording capability the Overtrail grade supports
- Lexus Service Connect, available via the Lexus app with up to a five-year trial, can relay Vehicle Health Reports and maintenance reminders directly to Lexus of Riverside, making it easier to stay on schedule
- The LX 700h features both an alternator and starter as standard, meaning the vehicle can continue running on engine power alone if the hybrid system becomes inoperative
Tire Maintenance and Replacement
Tire selection varies significantly across the LX lineup and directly affects rotation intervals and replacement costs:
- Premium, Luxury, Ultra Luxury grades: 20-inch alloy wheels (Premium) or 22-inch forged alloy wheels
- F SPORT Handling: 22-inch forged F SPORT wheels with Dark Gray metallic finish
- Overtrail: 18-inch matte gray metallic alloy wheels with 33-inch all-terrain tires
The Overtrail's all-terrain tires wear differently than standard road tires and should be rotated on the 5,000-mile schedule. A full-size spare tire is standard across all LX grades, which is a meaningful advantage for off-road-oriented owners in areas with limited service access.
Brake Service Intervals
The 2026 LX uses ventilated disc brakes front and rear. Front disc outer diameter measures 13.94 inches with a thickness of 1.26 inches, and rear discs measure 13.19 inches with a thickness of 0.79 inches. Given the LX's curb weight ranging from approximately 5,434 to 6,261 pounds depending on configuration, brake inspections at every oil change are recommended. The electronic parking brake is controlled via a center console switch and should be tested regularly.
Connected Maintenance Tools
The 2026 Lexus LX includes Service Connect with up to a five-year trial, available through the Lexus app. This system allows your vehicle to send maintenance reminders and vehicle health data directly to Lexus of Riverside so the service team can proactively contact you when service is due. Safety Connect is also included with up to a five-year trial and provides emergency assistance if needed during off-road excursions or highway travel around Riverside, San Bernardino, and Ontario.
