Maintenance Minder Answer Guide
Acura A1 and B1 Service Codes Explained
A1 and B1 are combinations of Acura Maintenance Minder items. This guide separates each letter and number so owners can understand the message before scheduling service.
Acura A1 service means replace the engine oil and rotate the tires. Acura B1 service means replace the engine oil and oil filter, complete Acura’s B-service inspections and rotate the tires. The letter is the main maintenance item; the number is a subitem shown at the same time.

How to read an Acura Maintenance Minder message
Start with the main letter, add every numbered subitem shown, and never assume a code from a different model year matches yours exactly.
Replace engine oil
The A main item is engine-oil replacement. It may be displayed with one or more numbered subitems.
Replace oil and filter; inspect
The B main item includes engine oil and filter replacement plus the defined brake, steering, suspension, fluid, exhaust and related inspections for the vehicle.
Rotate tires
Subcode 1 is tire rotation. That is why both A1 and B1 include a rotation.
Filters and drive belt
Common Acura guidance uses 2 for the air cleaner element, dust-and-pollen filter and drive-belt inspection.
Transmission fluid
Subcode 3 commonly calls for transmission-fluid replacement. Fluid type and procedure are vehicle specific.
Spark plugs and valve clearance
Subcode 4 commonly identifies spark-plug replacement and valve-clearance inspection.
Engine coolant
Subcode 5 commonly identifies engine-coolant replacement.
Model-specific fluid items
Some Acura owner guides use additional codes such as rear differential fluid or brake fluid. Confirm the exact meaning for the model and year.
Side-by-side
A1 and B1 are not interchangeable
Both include oil service and tire rotation, but B1 adds the oil filter and Acura’s B-service inspection list.
| Service item | A1 | B1 | Why it matters |
|---|---|---|---|
| Replace engine oil | Included | Included | Renews lubrication according to the vehicle’s calculated oil-life message. |
| Replace engine-oil filter | Not in A main item | Included | The B main item explicitly includes oil-filter replacement. |
| Rotate tires | Included | Included | Subcode 1 requests tire rotation; condition and wear should still be reviewed. |
| B-service inspection list | Not in A main item | Included | Includes model-applicable checks of brakes, steering, suspension, fluids, exhaust and related systems. |
| Additional numbered items | Only when another subcode is displayed, such as A12 or B16. | Every displayed number should be included in the appointment note and estimate. | |
Oil-life messages
When should you schedule A1 or B1 service?
The Maintenance Minder gives drivers a planning window before the maintenance becomes past due.
Price with context
How much does Acura B1 service cost in Queens?
A defensible answer separates a published offer from a final VIN-specific estimate.
There is no single B1 price for every Acura
The total can change with the model, year, engine and oil capacity, required parts, tire or brake condition, applicable taxes and any additional service the owner authorizes after inspection.
Paragon Acura’s current published offers provide useful reference points, but an offer is not automatically the final B1 price for every vehicle.
The estimate should identify the displayed code, included oil and filter service, tire rotation, inspection scope, applicable offer and any separately recommended item.
Published oil-service offer
Paragon currently publishes a full-synthetic oil change plus tire rotation at $99, with an alignment check included. Terms and eligibility apply.
Verify the live offerPublished Precision Service offer
Paragon currently publishes Acura Precision Service at $149 with synthetic oil service, multi-point inspection, tire rotation, brake measurement and report, and recall updates.
