What Honda B2 includes
- Replace engine oil and filter (the B): The core of every B service. Honda specifies 0W-20 full synthetic on most modern models.
- Full inspection (also the B): Brakes front and rear, suspension, steering ends, fluid levels, driveshaft boots, fuel lines and exhaust.
- Replace engine air filter (the 2): A restricted filter costs fuel economy before it costs power. A quick swap on most Civics, Accords and CR-Vs.
- Replace dust and pollen (cabin) filter (also the 2): Behind the glove box on most models. Weak vent airflow is the usual sign it is overdue.
- Inspect drive belt (also the 2): Inspect, not replace - cracking or glazing means it is aging, but a healthy belt stays.
B2 pairs the larger of Honda two oil services with the filter sub-code. B means replace the engine oil and oil filter, plus a full mechanical inspection. 2 means replace the engine air filter AND the cabin (dust and pollen) filter, and inspect the drive belt. No tire rotation is included, even though B2 often shows up alongside one.
