Reviewed for service schedule clarity.
The 2025 Acura Integra A-Spec is a front-wheel-drive compact sports sedan powered by a 1.5L turbocharged 4-cylinder engine. The A-Spec is an appearance and equipment package, available with either a CVT (Continuously Variable Transmission) or a 6-speed manual transmission. The mechanical maintenance requirements remain identical across all non-Type S trims .
This guide provides the complete factory preventive maintenance schedule based on the 2025 Acura Integra Owner's Manual, including the Maintenance Minder system, fluid specifications, severe-condition requirements, and time-based service intervals .
Key Takeaways
- The 2025 Integra uses the Maintenance Minder system instead of fixed odometer intervals . The vehicle's computer monitors driving conditions and displays alphanumeric codes (A, B, 1-7) when specific services are due. There is no traditional "every 30,000-mile" service schedule.
- The 1.5L turbo engine uses a timing chain, NOT a belt. The vehicle has a "100k+ miles no scheduled tune-ups" design . Code 4 covers only spark plugs and valve clearance inspection—not timing belt replacement.
- Premium fuel (91 octane) is recommended for the A-Spec model to achieve peak performance.
- Brake fluid replacement is strictly time-sensitive. If a Maintenance Minder indicator does not appear within 36 months after the previous reset of item 7, replace the brake fluid every 3 years regardless of mileage .
- Transmission fluid intervals differ by transmission type and driving conditions :
- CVT models driven regularly in mountainous/low-speed conditions: change every 25,000 miles (40,000 km)
- Manual transmission models under same conditions: change every 37,500 miles (60,000 km)
- If no service message appears within 12 months of reset, change the engine oil at least once per year .
- The Acura Maintenance Program covers the first 1 year or 12,000 miles of factory-scheduled maintenance, including standard oil changes, tire rotations, and multi-point inspections at participating dealerships .

Understanding the Maintenance Minder System
The 2025 Acura Integra does not have a traditional fixed‑mileage maintenance schedule. Instead, Acura employs a Maintenance Minder system that monitors vehicle operating conditions and calculates when service is required .
How the System Works
When the engine oil life reaches 15%, a wrench symbol illuminates on the driver information interface, and the system displays alphanumeric codes indicating which services are due .
| Oil Life Remaining | Message Displayed | Recommended Action |
|---|---|---|
| 15% | Maintenance Due Soon | Service should be scheduled soon; oil approaching end of life |
| 5% | Maintenance Due Now | Maintenance should be performed as soon as possible |
| 0% (Negative Distance) | Maintenance Past Due | Service is overdue – schedule immediately |
Oil Life Percentage Display
The system displays the calculated remaining engine oil life based on actual driving conditions :
| Displayed Oil Life (%) | Calculated Range (%) |
|---|---|
| 100 | 100-91 |
| 90 | 90-81 |
| 80 | 80-71 |
| 70 | 70-61 |
| 60 | 60-51 |
| 50 | 50-41 |
| 40 | 40-31 |
| 30 | 30-21 |
| 20 | 20-16 |
| 15 | 15-11 |
| 10 | 10-6 |
| 5 | 5-1 |
| 0 | 0 |
Viewing Maintenance Minder Information
To display Maintenance Minder information :
- Set the power mode to ON (do not start the engine)
- Rotate the right selector wheel until the Maintenance Minder screen appears
- The oil life percentage and due maintenance codes will display on the driver information interface
Fallback Time Requirements
The following requirements apply independently of the Maintenance Minder system :
| Condition | Required Action |
|---|---|
| No maintenance message within 12 months of reset | Change engine oil at least once per year |
| No item 7 indicator within 36 months of reset | Replace brake fluid every 3 years |
| Driving in dusty conditions | Replace air cleaner element every 15,000 miles (24,000 km) |
| Driving in urban areas with high soot | Replace dust/pollen filter every 15,000 miles (24,000 km) |
Maintenance Minder Codes
The Maintenance Minder communicates service needs through alphanumeric codes. A code consists of a main item (A or B) optionally followed by sub‑item numbers (1 through 7). The maintenance interval warning feature is standard equipment on the Integra .
Main Item Codes (A, B)
| Code | Required Service |
|---|---|
| A | Replace engine oil |
| B | Replace engine oil and oil filter; inspect front and rear brakes; check parking brake adjustment; check expiry date for tire repair kit bottle; inspect tie rod ends, steering gearbox, and boots; inspect suspension components; inspect driveshaft boots; inspect brake hoses and lines (including ABS/VSA) ; inspect all fluid levels and condition of fluids; inspect exhaust system; inspect fuel lines and connections |
Sub-Item Codes (1-7)
| Code | Service Description | Notes / Severe Conditions |
|---|---|---|
| 1 | Rotate tires | Standard tire rotation |
| 2 | Replace air cleaner element; replace dust/pollen filter; inspect drive belt | Dusty conditions: replace air cleaner every 15,000 miles (24,000 km) . High-soot urban areas: replace dust/pollen filter every 15,000 miles (24,000 km) |
| 3 | Replace transmission fluid | Mountain/low-speed driving requires more frequent changes (see severe conditions below) |
| 4 | Replace spark plugs; inspect valve clearance | NOTE: Timing belt replacement does NOT apply (timing chain engine). 100k+ mile tune-up interval |
| 5 | Replace engine coolant | Standard coolant replacement interval |
| 7 | Replace brake fluid | Every 3 years (36 months) regardless of mileage. If no item 7 indicator appears within 36 months after reset, replace brake fluid at that time |
Example Code Combinations
| Displayed Code | Services Required |
|---|---|
| A1 | Oil change + tire rotation |
| B2 | Oil/filter change + comprehensive inspection + air filters + drive belt inspection |
| A3 | Oil change + transmission fluid replacement |
| B7 | Comprehensive service + brake fluid replacement |
Engine Oil Change Guidance
Factory Requirements
| Specification | Detail |
|---|---|
| Recommended oil | SAE 0W‑20 premium-grade synthetic oil with API Certification Seal |
| Oil change trigger | Maintenance Minder code A or B (when oil life reaches 15%) |
| Maximum time interval | If no service indicated within 12 months, change oil at least once per year |
| Oil filter | Replace at every oil change (code B includes filter change) |
| Reference interval | Under normal driving, the Maintenance Minder typically triggers between 7,500-10,000 miles |
| Acura Maintenance Program | First 1 year/12,000 miles of oil/filter changes covered |
How to Check Oil Level
- Park on level ground and wait at least 3 minutes after engine shutdown
- Ensure the radiator fan is stopped before inspecting the engine compartment
- Pull out the dipstick and wipe completely clean
- Reinsert fully, then remove again
- 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
- Your Acura does not require any oil additives
- Check the engine oil level at least once per month
Transmission Fluid Service
The 2025 Integra A-Spec is available with either a Continuously Variable Transmission (CVT) or a 6-speed manual transmission. Service requirements differ by transmission type and driving conditions .
CVT (Continuously Variable Transmission)
| Specification | Detail |
|---|---|
| Transmission type | CVT (standard on A-Spec) |
| Specified fluid | Acura CVT Fluid (HCF-2) exclusively |
| Standard interval | Follow Maintenance Minder code 3 |
| Severe mountain driving interval | 25,000 miles (40,000 km) |
Critical Warning: Using any transmission fluid other than Acura CVT Fluid (HCF-2) can damage the transmission. Do not mix Acura HCF-2 with other transmission fluids. Any damage caused by using a non-equivalent fluid is not covered by Acura's new vehicle limited 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
| Specification | Detail |
|---|---|
| Transmission type | 6-speed manual (available on A-Spec) |
| Specified fluid | Acura MTF (Manual Transmission Fluid) |
| Temporary substitute | If Acura MTF is not available, SAE 0W-20 or 5W-20 motor oil may be used as a temporary measure. Replace with MTF as soon as possible. Motor oil does not contain the proper additives for the transmission and continued use can cause decreased shifting performance and lead to transmission damage |
| Standard interval | Follow Maintenance Minder code 3 |
| Severe mountain driving interval | 37,500 miles (60,000 km) |
> 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) .
DIY Warning: Acura recommends having a dealer check the fluid level and replace if necessary. Do not attempt to check or change the transmission fluid by yourself .
Spark Plugs & Ignition
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 4 |
| Inspect valve clearance | Code 4; adjust only if noisy |
| Timing belt replacement | Not applicable – Integra uses timing chain |
| Tune-up interval | 100k+ miles no scheduled tune‑ups |
Owner Guidance: The Integra's turbocharged engine places 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
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 5 |
| Coolant type | Acura Long Life Antifreeze/Coolant Type 2 (premixed 50/50) |
| Checking level | Check coolant level in the reserve tank at each fuel fill |
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/Clutch Fluid Replacement
| Specification | Detail |
|---|---|
| Specified fluid | Acura Heavy Duty Brake Fluid DOT 3 |
| Replacement trigger | Maintenance Minder code 7, or if no code 7 appears within 36 months after reset (every 3 years regardless of mileage) |
| Check frequency | Monthly; keep level between MIN and MAX marks on the reserve tank |
| Temporary substitute | DOT 3 or DOT 4 from a sealed container |
| DOT 5 warning | NOT compatible – brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage |
| Clutch fluid | Manual transmission models use the same reservoir for clutch fluid |
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.
Owner Guidance: A complete system flush (draining old fluid from each caliper) is required. Topping off the reservoir is not sufficient. If the brake fluid level is at or below the MIN mark, have a dealer inspect the vehicle for leaks or worn brake pads as soon as possible .
Using Non-Acura Brake Fluid: Using any non-Acura brake fluid can cause corrosion and decrease the longevity of the system. Have the brake system flushed and refilled with Acura Heavy Duty Brake Fluid DOT 3 as soon as possible if a substitute is used .
Drive Belt Inspection
| Specification | Detail |
|---|---|
| Inspection trigger | Maintenance Minder code 2 (inspect drive belt) |
| Replacement | Replace if cracked, frayed, glazed, or making a squealing noise on startup |
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)
| Filter | Replacement Trigger | Severe Conditions Note |
|---|---|---|
| Engine air cleaner element | Maintenance Minder code 2 | If you drive in dusty conditions, replace every 15,000 miles (24,000 km) regardless of Maintenance Minder |
| Cabin air filter (dust/pollen filter) | Maintenance Minder code 2 | If you drive primarily in urban areas with high soot concentrations (industry, diesel vehicles), replace every 15,000 miles (24,000 km) |
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.
Reset Procedure :
- Set the power mode to ON (do not start the engine)
- Rotate the right selector wheel until the Maintenance Minder screen appears
- Press and hold the right selector wheel for about 10 seconds to enter reset mode
- Rotate the right selector wheel to select a maintenance item to reset, or select All due items (you can also select Cancel to end the process)
- Press the right selector wheel to reset the selected item
- Repeat from step 4 for other items you wish to reset
> 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.
Monthly & Pre-Drive Checks
As outlined in the 2025 Integra Owner's Manual, perform these checks regularly :
| Frequency | Check Item |
|---|---|
| Monthly | Brake/Clutch fluid level (keep between MIN and MAX marks) |
| Monthly | Tire pressure (including spare); examine tread for wear and foreign objects |
| Monthly | Exterior lights operation |
| Every 6 months | Wiper blade condition |
| Pre-drive / Before long trips | Engine oil level; windshield washer fluid; tires for damage; fluid leaks under vehicle |
Service Flexibility
Maintenance may be done by any qualified automotive repair establishment or individual using parts certified to EPA standards. 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. However, all maintenance services should be performed in accordance with the intervals indicated by the driver information interface.
Acura Precision Certified Pre-Owned Vehicles: Some 2025 Integra models may be offered as Precision Certified, which includes the first scheduled maintenance free and a 182-point inspection .
Severe Driving Conditions
The Maintenance Minder system automatically adapts to driving conditions, but the following severe condition requirements apply independently of the Maintenance Minder :
| Condition | Required Action |
|---|---|
| Mountain driving at very low speeds (CVT) | Change CVT fluid every 25,000 miles (40,000 km) |
| Mountain driving at very low speeds (Manual) | Change manual transmission fluid every 37,500 miles (60,000 km) |
| Dusty driving conditions | Replace air cleaner element every 15,000 miles (24,000 km) |
| Urban driving with high soot concentration | Replace dust/pollen filter every 15,000 miles (24,000 km) |
| No service message for 12 months | Change engine oil regardless of mileage |
