2026 Acura Integra Complete Service & Maintenance Schedule

The 2026 Acura Integra represents the return of a legendary nameplate, offered in sedan form with a choice of two powertrains: a standard 1.5L turbocharged 4-cylinder engine (CVT) and a high-performance 2.0L turbocharged 4-cylinder engine (6-speed manual or CVT) for the Integra Type S (refer to your specific model's Owner's Manual for exact engine verification).

This guide provides the complete factory service schedule based on the 2026 Acura Integra Owner's Manual, including the Maintenance Minder system, fluid specifications, critical service intervals, and severe-condition requirements .

Key Takeaways

• The 2026 Integra uses the Maintenance Minder system instead of fixed odometer intervals . The vehicle's computer monitors driving conditions (speed, temperature, time, and driving habits) and displays alphanumeric codes (A, B, 1-7, 9) when specific services are due. There is no traditional "every 30,000-mile" service schedule.
• The 1.5L and 2.0L turbo engines use timing chains, NOT belts. Unlike older Acura V6 models that required timing belt replacement, both the L15 and K20 engines in the 2026 Integra utilize timing chains that require no scheduled replacement. Code 4 covers only spark plugs and valve clearance inspection .
• Premium fuel (91 octane or higher) is recommended for the 1.5L engine and required for the 2.0L Type S to achieve rated horsepower and prevent engine knock.
• Brake fluid replacement is strictly time-sensitive. If a Maintenance Minder indicator does not appear within 36 months after the previous reset, replace the brake fluid every 3 years regardless of mileage .
• Major periodic service should generally be done every 2 years or after 30,000 kilometers (approximately 18,600 miles) .
• Transmission fluid intervals differ by transmission type. For CVT models driven regularly in mountainous/low-speed conditions, change CVT fluid every 25,000 miles (40,000 km). For manual transmission models under the same conditions, change every 37,500 miles (60,000 km) .
• Service at a dealer is not mandatory to maintain warranty coverage. Maintenance may be performed by any qualified automotive repair establishment or individual using certified parts. According to state and federal regulations, failure to perform maintenance on items marked # will not void your emissions warranties .

Engine & Drivetrain Overview

The 2026 Acura Integra is available with multiple powertrain configurations:

Timing Chain vs. Belt: Both the L15 and K20C1 engines use timing chains that do not require periodic replacement. Code 4 on the Maintenance Minder applies only to spark plugs and valve clearance inspection—not timing belt replacement .

Understanding the Maintenance Minder System

The 2026 Acura Integra does not have a traditional fixed‑mileage maintenance schedule. Instead, Acura employs a Maintenance Minder system that monitors vehicle operating conditions (engine temperature, speed, time, and driving habits) and calculates when service is required .

How the System Works

When the oil life reaches 15%, a wrench symbol and system message indicator illuminate on the driver information interface, and the system displays alphanumeric codes indicating exactly which services are due .

Oil Life Percentage Table

The system displays the calculated remaining engine oil life in percentages :

Viewing Maintenance Minder Information

To display Maintenance Minder information :

1. Set the power mode to ON (do not start the engine)
2. Rotate the right selector wheel until the Maintenance Minder screen appears
3. The oil life percentage and due maintenance codes will display on the interface

Independent (Time-Based) Requirements

The following requirements apply independently of the Maintenance Minder system :

Fallback Time Requirements Summary

Maintenance Minder Codes

The Maintenance Minder communicates service needs through alphanumeric codes. A code consists of a main item (A, B, 0, or 9) optionally followed by sub‑item numbers (1 through 7) .

Main Item Codes (A, B, 0, 9)

Sub-Item Codes (1-7)

Example Code Combinations

Factory Requirements

How to Check Oil Level

1. Park on level ground and wait at least 3 minutes after engine shutdown
2. Ensure the radiator fan is stopped before inspecting the engine compartment
3. Pull out the dipstick and wipe completely clean
4. Reinsert fully, then remove again
5. Oil level should be between the upper and lower marks

Owner Guidance

• Acura Genuine Motor Oil is recommended, though any synthetic oil of the same viscosity grade and API certification is acceptable
• Do not press the engine cover forcibly, as this may damage the engine cover and component parts
• Your Acura does not require any oil additives
• Check the engine oil level at least once per month

Safety Precautions Before Any Maintenance

Before performing any maintenance :

• Vehicle must be stationary – park on level ground, set the parking brake, engine off
• Ensure radiator fan is stopped – the fan may operate even when power mode is in VEHICLE OFF
• Let engine and exhaust cool thoroughly before touching any parts (hot parts can burn you)
• Do not start the engine unless instructed – keep hands and limbs away from moving parts
• Do not open the hood while Auto Idle Stop function is activated

Transmission Service (CVT vs. Manual)

The 2026 Integra is available with either a Continuously Variable Transmission (CVT) or a 6-speed manual transmission. Service requirements differ.

CVT (Continuously Variable Transmission)

Critical Warning: Using any transmission fluid other than Acura CVT fluid can damage the transmission. Do not use automatic transmission fluid (ATF) in a CVT. Any resulting damage is not covered under warranty .

> Severe condition: If you regularly drive your vehicle in mountainous areas at very low vehicle speeds, this results in higher transmission temperature. Under this condition, have the transmission fluid changed every 25,000 miles (40,000 km) .

6-Speed Manual Transmission

> Severe condition: For manual transmission models regularly driven in mountainous areas at very low speeds, have the transmission fluid changed every 37,500 miles (60,000 km) .

Spark Plug Replacement

Owner Guidance: The Integra's turbocharged engines place additional stress on spark plugs. If you notice rough idle, reduced fuel economy, or hesitation before the Maintenance Minder indicates replacement, have the plugs inspected early. Use only OEM-specified spark plugs (NGK or Denso equivalents).

Engine Coolant Service

Owner Guidance: Do not add straight antifreeze or water; the factory coolant is premixed. If Acura coolant is unavailable, a major brand of non‑silicate coolant may be used as a temporary replacement; return to Genuine Acura coolant as soon as possible. Turbocharged engines place additional thermal stress on cooling system components—inspect hoses regularly for swelling or cracking.

Brake Fluid Replacement

Why it's critical: Brake fluid is hygroscopic – it absorbs moisture from the air over time. This moisture lowers the fluid's boiling point (potential brake fade under hard braking) and promotes internal corrosion of the brake system (calipers, master cylinder, ABS modulator).

Owner Guidance: A complete system flush (draining old fluid from each caliper) is required. Topping off the reservoir is not sufficient. Check the brake fluid level monthly and keep between MIN and MAX marks. Code 9 also indicates service front and rear brakes .

Drive Belt Inspection

Owner Guidance: The Integra uses a serpentine drive belt that powers the alternator, air conditioning compressor, and other accessories. Most drive belts last between 60,000 and 90,000 miles, but the Maintenance Minder indicates when inspection is needed.

Air Filters (Engine & Cabin)

Owner Guidance: Both filters are inexpensive and can be replaced without special tools. The cabin air filter is typically located behind the glove box; replacing it annually improves interior air quality and HVAC performance. A clogged engine air filter can reduce fuel economy and turbocharger performance.

Resetting the Maintenance Minder Display

After performing the required maintenance service, the engine oil life display must be reset. Failure to reset results in the system showing incorrect maintenance intervals, which can lead to serious mechanical problems.

Reset Procedure :

1. Set the power mode to ON (do not start the engine)
2. Rotate the right selector wheel until the Maintenance Minder screen appears
3. Press and hold the appropriate button (usually the SEL/RESET button) to enter reset mode
4. Select Reset using the selector wheel
5. The oil life display returns to 100%

> Note: The dealer will reset the engine oil life display after completing required maintenance service. If someone other than a dealer performs maintenance service, reset the engine oil life display yourself.

Tire Pressure Monitoring System (TPMS)

The 2026 Integra is equipped with a Tire Pressure Monitoring System (TPMS) that monitors each tire's pressure individually.

> Note: The TPMS is not a substitute for proper tire maintenance—it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger the TPMS warning .

Monthly & Pre-Drive Checks

As outlined in the 2026 Integra Owner's Manual, perform these checks regularly :

Daily inspections should be performed :

• Before long-distance trips
• When washing the vehicle
• When refueling

Severe Driving Conditions

The Maintenance Minder system automatically adapts to driving conditions, but the following severe condition requirements apply independently of the Maintenance Minder and are explicitly stated in the Owner's Manual :

Major Periodic Service Interval

For major periodic service, this should generally be done every 2 years or after 30,000 kilometers (approximately 18,600 miles) .

Scheduled Maintenance Summary

Since the Integra uses the Maintenance Minder system instead of fixed intervals, the table below shows reference intervals—always follow your vehicle's displayed Maintenance Minder codes:

Long‑Term Ownership Summary

• No timing belt replacement required: The Integra uses timing chains on both engine options. This eliminates the expensive 7‑year/105,000‑mile belt replacement required on older Acura V6 models. Code 4 applies only to spark plugs .
• Follow the Maintenance Minder, not arbitrary fixed schedules: The system adapts to your driving habits. Trust the codes displayed on your dashboard. However, note that oil should be changed at least once per year even if no code appears .
• Premium fuel is recommended/required: Acura recommends 91‑octane premium fuel for the 1.5L engine and requires it for the 2.0L Type S for optimal performance and to prevent engine knock.
• Transmission fluid intervals are severity-dependent: Mountain/low-speed driving requires much shorter intervals—25,000 miles (40,000 km) for CVT; 37,500 miles (60,000 km) for manual .
• Brake fluid is strictly time-critical: Replace every 3 years regardless of mileage or Maintenance Minder codes. If item 7 does not appear within 36 months of reset, replace it at that time .
• Use Acura-specified fluids: CVT fluid (Acura CVT/HCF-2), coolant (Type 2), and brake fluid (DOT 3) are critical for proper operation. Using non-spec fluids can cause damage not covered by warranty.
• Valves require attention only if noisy: Adjust valves during services A, B, 1, 2, or 3 only if they are noisy .
• Service anywhere, keep records: Maintenance may be done by any qualified automotive repair establishment or individual using EPA-certified parts. This does not void your warranties. According to state and federal regulations, failure to perform maintenance on items marked with # will not void your emissions warranties. All maintenance services should be performed in accordance with the intervals indicated by the driver information interface .
• Reset the Maintenance Minder after service: Failure to reset results in incorrect maintenance intervals .
• Parts and fluids: The use of Acura Genuine Parts and fluids is recommended. Acura Genuine Parts are manufactured according to the same high quality standards used in Acura vehicles .
