Refueling Procedures

Proper refueling techniques to ensure safety and optimal performance.

Park vehicle on level surface and turn engine off.
Locate fuel door release lever on driver's side floor area.
Remove fuel cap by turning counterclockwise.
Insert fuel nozzle completely into filler neck.
Fill tank until nozzle automatically shuts off.
Replace fuel cap and turn clockwise until clicks.
Close fuel door securely.

WARNING! Never overfill tank; do not smoke during refueling; avoid static electricity discharge.

Fuel System Components

Major components of the MDX fuel delivery system.

Fuel tank: 19.5 gallon capacity with integrated fuel pump.
Fuel pump: Electric in-tank pump with filter.
Fuel injectors: Direct injection high-pressure injectors.
Fuel rail: High-pressure fuel distribution system.
Fuel pressure regulator: Maintains optimal injection pressure.
Fuel filter: Integrated with fuel pump assembly.
Evaporative emission system: Prevents fuel vapor release.

CAUTION! Fuel system operates under high pressure; do not service without proper training.

Fuel Economy Optimization

City Driving: 19 MPG estimated with proper maintenance.
Highway Driving: 27 MPG estimated with conservative driving.
Combined: 22 MPG typical with mixed driving conditions.
Driving Tips: Smooth acceleration, proper tire pressure, regular maintenance.
Idle Reduction: Avoid extended idling to conserve fuel.
Cruise Control: Use on highways for consistent speed.
Weight Management: Remove unnecessary cargo weight.
Aerodynamics: Keep windows closed at high speeds.

Maintenance Schedule

Fuel system maintenance intervals and procedures.

Regular Maintenance: Fuel filter inspection every 30,000 miles, fuel system cleaning every 15,000 miles, fuel cap inspection with each service.

Fuel Injector Service: Professional cleaning recommended every 30,000 miles. Fuel Pump: Inspect during major services. Evaporative System: Check for leaks during emissions testing. Fuel Lines: Visual inspection for damage or leaks during oil changes.

Fuel System Diagnostics

Trouble codes and diagnostic procedures for fuel-related issues.

Check engine light: Scan for fuel system codes (P0171, P0087, etc.).
Fuel pressure test: Verify pump output and regulator function.
Injector testing: Check spray pattern and flow rates.
Fuel quality test: Analyze for contamination or water content.

Tip: Always start diagnostics with fuel pressure verification and quality check.

Fuel Quality Requirements

Importance of using high-quality premium gasoline.

Use top-tier gasoline: Prevents carbon buildup on intake valves.
Avoid ethanol blends: E85 not compatible; E15 acceptable but not recommended.
Storage considerations: Use fuel stabilizer for long-term storage.
Water contamination: Avoid filling during tanker delivery at stations.
Additive use: Acura recommends fuel system cleaners every 7,500 miles.
Octane importance: Lower octane may cause knocking and reduced power.
Detergent quality: Prevents injector clogging and combustion chamber deposits.

WARNING! Using regular gasoline may void warranty coverage for engine damage.

Emergency Procedures

Fuel-related emergency situations and responses.

Warranty Information

Fuel system coverage under Acura warranty terms.

Basic Warranty: 4 years/50,000 miles. Powertrain: 6 years/70,000 miles. Fuel System: Covered under powertrain warranty. Exclusions: Damage from improper fuel or additives not covered.

CAUTION! Using incorrect fuel type may void warranty coverage; keep fuel receipts for documentation.
